Finest Bike Pc for Climbing: Garmin vs Hammerhead vs Wahoo

March 17, 2022

Lengthy gone are the times of motorbike computer systems displaying you only a single elevation profile on your total route, and even simply the near-term elevation profile. Lately, the bike computer systems will mechanically break down and even categorize the climbs in your deliberate route, together with rea-time standing, till the struggling is full. And on this case, I’ve finished quite a lot of struggling for this one.

This can be a put up and video I’ve been engaged on since final summer season, and every time I went out to shoot this video, a sure firm (cough…Hammerhead) would actually launch a considerable replace to their climbing app characteristic the next day or week. With out fail, each…single…time. Be it final August or final December, it stored occurring.

So clearly, the one resolution to that was to re-test and re-shoot it once more with the brand new options, which in fact require going out and using one other epic climb. Thus, the video above. Masking 5 epic climbs from the Dolomites to Switzerland, and each off-road and on-road climbs in Tenerife and the Canary Islands. Plus quite a few different climbs alongside the best way. In some instances, these have been gigantic single climbs up a volcano, and in others it was a collection of climbs, each of which check the options in several methods.

You’ll discover I didn’t listing a selected model/mannequin for the three foremost firms. That’s as a result of from a technical standpoint, the options are equal amongst their newest items for climbing functions. Thus, particularly, these items:

Garmin: Edge 530, Edge 830, Edge 1030, Edge 1030 Plus
Hammerhead: Karoo 1, Karoo 2
Wahoo: ELEMNT, ELEMNT BOLT V1/V2, ELEMNT ROAM

For instance, there’s no variations between an Edge 530 and Edge 1030 Plus in relation to climbing options (apart from simply display measurement). Identical goes for Wahoo ELEMNT ROAM vs BOLT. Observe that the Edge 130 Plus does have ClimbPro, however simply not the coloring because it’s a black and white display.

Pre-Trip:

The primary element to grasp is that every one of those require some quantity of pre-ride planning to allow. That means, that all of them require you might have a course loaded with the intention to perform. Not like one thing like Strava Dwell Segments, which largely mechanically set off, the climb features on Garmin & Hammerhead want a route loaded. As for Wahoo? Nicely, there’s really virtually no climb features there, however as an alternative, you should use Strava Dwell Segments in a pinch, however you’ll wish to do some planning there to make sure these particular segments match your climbs.

So, let’s begin with a route I’ve created with Strava, after which synced to the gadgets. At this level, there’s no variations when it comes to the supply (e.g. Strava vs Komoot vs others, and actually, I exploit routes from completely different platforms on this piece). That’s all a wash. With that synced over to the gadgets, the items give me an summary of what’s the day’s route entails.

Within the case of Garmin, pre-ride, they’ll present your deliberate map route, some basic stats round distance and elevation, in addition to every particular person climb element. So I can take a look at all of the auto-categorized climbs, and even faucet right into a single given climb to see the ache there.

Subsequent, on the Hammerhead unit, they don’t present any climb knowledge pre-ride within the course choice display. You’re going to get to see the climbs when you load the highway (identical to on Garmin), however they don’t seem on the pre-ride screens. Nor does Hammerhead present any course profile info, although, they do present the estimated whole ascent, which I’ve discovered is nearly all the time vastly incorrect and overestimated (an accuracy thread we’ll see extra of on this put up).

Equally, Wahoo doesn’t present something pre-ride when selecting a route, aside from the course size remaining (on this case, I didn’t have a useful picture of this subsequent to the course, so it consists of the gap from me to the beginning of the course).

By way of altering climb-related settings, Wahoo has none. Nevertheless, Hammerhead does help you tweak the climb categorization within the menus. I left it for defaults.

And the identical goes for Garmin, which additionally permits you to tweak which measurement of climbs to point out, whether or not or not a climb notification seems, and which knowledge fields are proven on the backside.

With that, I’ll choose the climbs and get rolling.

Upcoming Climbs:

Okay, with our trip underway, let’s now take a look at what it reveals on the gadgets as you begin your trip when it comes to upcoming climb knowledge. All of those are configurable on every machine – so you possibly can disable this should you don’t need it in fact. On this case, we is likely to be distant from a climb on flat floor, such because the above picture, which locations us 11KM from the primary climb (although, discover how Hammerhead and Garmin differ within the begin of that climb).

First up, on the Garmin, you might have the ClimbPro web page. This web page will by default present the upcoming climb listing, until you’re in a climb, through which case it’ll present the present climb particulars (extra on that within the subsequent part).

On a Hammerhead machine, you’ll get the same web page (this was launched final December). This web page will present you the gap till the beginning of every climb, the typical gradient, after which the size of the climb. If you happen to faucet a climb, it’ll broaden out to point out you that particular climb.

Within the case of Wahoo, they don’t present any upcoming climb categorized. As a substitute, they do present the upcoming elevation profile (as does Garmin/Hammerhead on different pages). You may regulate the dimensions of this, but it surely’s simply displaying you the general profile, not any knowledge metrics concerning the climb or climbs arising.

After I evaluate Garmin & Hammerhead when it comes to this upcoming climbs web page, each of them are fairly related. As with most issues on the Karoo, the Hammerhead web page is UI-wise prettier, each within the listing perspective in addition to the person climb perspective. However functionally talking, it’s principally a wash between the 2.

The principle factor you’d discover facet by facet is that Garmin and Hammerhead categorize climbs barely in a different way, when it comes to begin/finish factors in addition to double-climb eventualities. For instance, whereas main climbs are sometimes tremendous clear in the place they begin/cease, it’s the smaller climbs with extra shallow begins that differ. If we take a look at climbs which have a number of items to them (e.g. you go up a very long time, then perhaps flatten out or descend for 30-60 seconds earlier than going up a very long time once more), Garmin tends to group that as a single climb. Whereas Hammerhead will typically break up that out.

The exact break up varies, however I’d say usually Garmin aligns higher with the way you’d describe a climb to your buddies at a café, “Man, that climb lasted 15KM with 8% gradient”, whereas Hammerhead tends to be the always-right school-teacher about it, “Nicely really, that climb was 8KM, then a 200m break, then 6.8KM extra”. Thus why on some routes Garmin would say I had 4-5 main climbs, and Hammerhead can be like “Yo, you’ve obtained 18 climbs!”. Like ice cream preferences, to every their very own.

Each firms publish how they categorize climbs, right here for Garmin, and right here for Hammerhead. The important thing distinction is Garmin requires 500m in size minimal, whereas Hammerhead is 400m in size. Each require a minimal grade of three%.

Throughout Every Climb:

Now comes the great half, what you see throughout every climb. Within the case of each Hammerhead and Garmin, it should first notify you as you method the climb, then the person climb pages will mechanically get enabled once you cross the edge of the beginning of the climb. In fact, that threshold would possibly differ between the businesses, as famous earlier.

Within the case of Garmin’s ClimbPro, you’ll see a web page for that particular climb. On the high it’ll say which climb # it’s (e.g. Climb 1 of 4), in addition to the gap till the subsequent climb. Under that, you’ve obtained the gap remaining on this climb, in addition to the ascent remaining on this climb. These fields replace as you trip, finally whittling your manner all the way down to zero.

You’ll additionally see the climb profile, with color-coded chunks, and your place on the climb, in addition to the typical gradient remaining for the climb. Nevertheless, remember the fact that it’ll really zoom in on a piece of the climb, relatively than present all the factor. I really don’t like this explicit facet of it, and wished it simply stayed placed on all the climb. On the very backside of the web page are two customizable knowledge fields. In my case, they’re present grade and elevation.

Garmin’s color-coding is predicated on official UCI categorization of climbs, which in flip is predicated how a lot elevation you achieve in a given time interval. The darker the colour, the extra painful it’s.

Cat 4 > 8000
– Inexperienced
Cat 3 > 16000
– Yellow/Gold
Cat 2 > 32000
– Orange
Cat 1 > 48000
– Purple
HC (Hors Class) > 64000 – Darkish Purple

Subsequent, we’ve obtained Hammerhead and their particular person climb web page. This web page simply takes the cake on the prettiest climb web page, with theoretically essentially the most element. It’s supplied in each a half display peak and full-height choice:

Their color-coding is as follows:

0-4.4%: Darkish inexperienced
4.6-7.5%: Mild inexperienced
7.6-12.5%: Yellow
12.6-15.5%: Pink/peach
15.6%-19.5%: Orange
19.6%-23.5%: Purple
23.5%+: Purple

For the higher portion you’ve obtained all the climb displayed in 500m lengthy coloured increments, alongside along with your place on it (and your accomplished portion shaded). I instantly like this higher than the Garmin method which zooms in. It’s additionally obtained color-coding on the pain-factor all through the principle climb particulars. Under that may be a listing of numbers that scroll by. These are 100m lengthy chunks with the anticipated gradient in every of these chunks. So principally, you possibly can see the subsequent 500m with of gradient inside the scrolling ticker.

The issue although? This knowledge isn’t correct. Particularly on the extremes (e.g. greater grades), hairpin turns, or in mountainous terrain. It is because no matter knowledge supply they’re utilizing merely isn’t granular sufficient for this. So numerous occasions it’ll say I’ve obtained a 14% chunk arising, and it’ll simply be extra of the identical 4-6% I’ve been using (just like the above picture). After I requested Hammerhead about this beforehand, they acknowledged the difficulty, saying:

“Now we have been wrestling a few of these elevation knowledge errors and methods to raised deal with unrealistic spikes or swings within the knowledge. Your instinct is right in that it’s typically primarily based on the underlying dataset that we’re utilizing for a specific area. Now we have obtained our arms on many of the available ones and are working some experimentation on how one can deal with dangerous knowledge. We match offline elevation knowledge for a complete downloaded nation onto Karoo 2 in order that even re-routes can have Climber performance. This offline performance additionally implies that we will’t depend on any backup or massaging of the information from completely different sources on an internet server. Now we have a number of strategies we’re to enhance this.”

Finally, this turns into a case of kind over perform. Sure, it visually seems to be tremendous cool. However virtually talking, it’s typically inaccurate (the truth is, virtually all the time inaccurate). And it’s finally why Garmin in all probability isn’t displaying such granular element. In Garmin’s case, they’re slicing it up into far bigger chunks for color-coding, which implies they will clean out a few of the underlying knowledge inconsistencies. Under is an efficient instance of dangerous knowledge – this highway by no means had wherever even remotely near a 25% grade part (nor one then adopted apparently by –9.3% downhill part). Nevertheless, should you look intently on the yellow Garmin part under, you possibly can see what seems as a spike within the climb, however in Garmin’s case they aren’t granular sufficient displaying knowledge associated to that, to attract your consideration to it.

Anyhow, under that streaming gradient ticker part, is the gap to the highest, and the elevation to the highest (plus climb # and present grade). One fascinating word although, is that Hammerhead doesn’t correctly rely mid-climb descents right here. So for instance you see that little bump the place I am going down for a number of hundred meters on the above? In that case, Hammerhead doesn’t precisely present my whole ascent as having to ‘reclimb’ that portion twice. As a substitute, their math is just your objective elevation (high), minus the present elevation. So any temporary downs inside it aren’t calculated appropriately, and can undercount how a lot climbing you really must do nonetheless. In case your climb has no temporary descents, then it’s a non-issue.

Nonetheless, if we step again and take a look at the general gist of what the ticker and climb charts are displaying you, I believe Hammerhead is basically on the appropriate path right here. I think in the event that they shifted away from 100m sections, and as an alternative went extra in the direction of 200m or bigger sections, it’d be sufficient to get round a few of the short-distance accuracy points they’ve. And equally, fixing the ascent to high ought to be simple since they know the descents simply as a lot as they know the ascents.

As for Wahoo, once more, they don’t have any direct climbing characteristic. However they do even have one workaround: Strava Dwell Segments. If you happen to star/favourite a Strava Dwell Phase for that climb (which is often simple sufficient to search out/tag), it’ll set off as you method the climb after which present your precise distance until the tip of the climb. Plus the upcoming elevation profile. It received’t present ascent or different climbing-related metrics, but it surely a minimum of reveals how a lot struggling you might have left, together with how poorly you’re doing relative to all your folks.

Although, on one explicit lengthy climb final yr, I simply adopted Wahoo’s BOLT for my very own Haribo-Professional. One gummy per 1KM remaining. Albeit, this does impression show visibility, however, once you’re climbing for hours on finish with out climbing metrics, you principally get into the groove anyhow.

Lastly, some will ask about precise gradient responsiveness. That means, how briskly does every bike pc reply to gradient shifts and show that on the unit itself. And the reply is “it relies upon”. On the whole, it appeared just like the Hammerhead and Wahoo items reported shifts in gradient extra shortly because the highway modified pitch. However not on a regular basis. Within the video I present a bit virtually again to again the place on one highway chunk the Garmin lagged, however then moments later it was the Wahoo lagging. Take into accout, after I say ‘lagging’, we’re speaking a few seconds. You may see examples of the variations.

The rationale for that’s that these firms are largely ahead motion to find out grade, not the present angle of your bike. So that they take a look at how a lot elevation you’ve gained within the final X seconds, after which determine the gradient primarily based on the gap you travelled. It’s a positive line between being too fast to reply to shifts in stress (which might result in inaccurate knowledge), and being too sluggish (which results in frustration). For just about each situation I encountered, there have been no significant real-world variations between them on this matter.

Within the sense that, sure, typically one unit was behind one other a number of seconds, however until this was crossing a shallow 100m lengthy bridge, it simply didn’t make an enormous distinction to me that it was 2-3 seconds behind displaying 6% vs 8%. For any significant climbs, it evened out inside a number of seconds and confirmed me seemingly right values throughout all gadgets.

Going Ahead:

In fact, as we method the springtime, we traditionally see features on biking head items. It’ll be fascinating to see if there are shifts right here, from all of the gamers. I believe it’s clearly essential that Wahoo someway get on this realm, particularly as Hammerhead continues to enhance theirs with every iteration each few months. In the meantime, Garmin may look so as to add a bit extra element like Hammerhead, whereas Hammerhead inversely may goal to try to get their underlying gradient knowledge both extra correct or maybe much less granular to, in flip, enhance upcoming gradient accuracy.

After which past that, all the businesses may introduce added climbing options that haven’t been considered but. There’s numerous methods this could possibly be expanded, and we solely want to have a look at different characteristic areas to see that. For instance, Garmin not too long ago launched enhanced waypoints assist (known as ‘Up Forward’) on their Fenix 7/Epix collection, or, no one has made a manner for this to be sans pre-loaded route – a long-requested characteristic by many.

Or, the businesses may do a greater job of surfacing these climbs of their post-ride analytics apps, displaying the occasions and efforts after the very fact, much like Strava Segments, however with out all of the jumble of quite a few segments. Only a clear listing of the climbs and one’s performances on these climbs.

Nonetheless, each the Hammerhead and Garmin climbing options stay my favourite options on every unit. Maybe much less for technical causes, and extra for nostalgia causes. In my case, after I’m utilizing these options to their fullest extent, it’s as a result of I’m off on some bike journey someplace – typically on an epic climb with superb surroundings. And because the snow melts, it’s virtually time for that to start once more. So if and when these firms make modifications, I’ll be able to put them to the check once more.

With that – thanks for studying!
