Hammerhead Wahoo

As you may be aware, I’ve gained a Wahoo Bolt version 2. I’ve also gained a Hammerhead Karoo 2. I’ve been weighing up the pros and cons of each, in order to decide who gets the priority on my bars. We shall start with the wahoo. I’ve time for wahoo, I’ve previously used the original ELEMNT, and found it very good.

So, the bolt has had a couple of issues, but they appear to of been sorted with firmware updates. So, feature wise, the bolt is feature sparse. It does routes, strava segments and everything else you’d expect a gps unit to do. It doesn’t have the climber feature that the Karoo has. But what it does, it does really well. I find it easy to glance down, and see what I need quickly and easily. Even in bright sunlight it’s clear and easy to see. The size however can be an issue. At times, it can just be a little small, especially with turn by turn directions where the instruction is quite long. Wahoo have addressed this by increasing the font size, but sometimes it can still be too small.

The map is detailed enough to see upcoming roads and details, it does however lack certain details. The changes wahoo have made to the maps have been beneficial to the bolt, with inbuilt elevation and street details making on device routing quick and easy.

The varia radar works with clear distinct tones, one thing that irks me, is while the radar is connected, the green bar is permanently on screen, mind you this is the same on all garmin units too. Overall, I like the unit.

The Karoo is a beast. Both in size and power. Based on android, it’s closer to a mobile phone than GPS. It is an excellent unit for exploring, with incredible mapping, that includes many POI and details. Where this unit falls down for me, is readability in sunlight. It’s not great.

However, the varia radar bar does disappear when it’s not required. Sensor wise, both units pair to all sensors you’d expect. Power meters, varia, speed, heart rate etc. One bonus for the Karoo, is that like Garmin units, it can control smart lights. Not with the finesse of Garmin units, but it’ll turn them on at the start of a ride, and off at the end. Both units have issues with my stages gen2 crank. Neither will calibrate, and the hammerhead only connects over BlueTooth. Ant+ causes the power meter to drop out often. To be fair, I’ve not tried calibration on the bolt after the last couple of updates, and hammerhead are saying they are working on power meter code. Both units on that note get regular updates, with Karoo every couple of weeks, and the bolt less frequently.

Update: as of firmware WA20-12513. The bolt now correctly calibrates the Power meter. Karoo have also released an update 1.220.1066 which states they have fixed the issue, but I’ve yet to test. Now I’ve given the hammerhead a quick test to see, and it does calibrate. I shall ride with it tomorrow and see about dropouts.

Using the unit, I find myself looking at it far longer than the bolt, partly due to glare, partly due to having to hunt for what I need. Swiping the data rich pages is a pleasure, each page coming on per swipe. But I don’t get that instant data I get with the bolt. And that’s an issue to me. However, if I was exploring a new area, the Karoo is my choice due to routing, maps and accuracy. If I’m just out on a ride, following a route or not, the bolt is on my bars.

New and old

A new bike computer.

So, I managed to get hold of the he Wahoo ELEMNT bolt. This second version adds a new colour screen, new buttons and some new bugs and issues.

So, while most of the bloggers are going on about the new screens, convex buttons and on device routing, I find some of the bugs quite problematic. Especially the elevation issue. It just reads far too high, and no way of calibrating it.

Apart from this, I’m enjoying the new unit. In order to mount this, I also got hold of an Excellent mount, the Form Mount. Installation was a tad painful, but it’s an excellent mount with a lot of customisation.

I’ve also ditched my look keo blade pedals. They required a service as they where starting to sound rough as hell. Could I find away of stripping them down? Nope. There are videos on YouTube on how to service them, and yet my pedals didn’t match anything at all. No bolts, no flats, nothing. So, back on my trusty shimano R550. At least they can be fully stripped, cleaned and greased without any drama.

And oddly comfortable.

Any way, I’m off to play with the wahoo data fields.

First ride for ages

It’s been awhile since I had the old boy out the garage for a ride.

But today was the day for it. I got changed, checked all the batteries, and set off. Just a short run out to Ripley. My backside was aching quite quickly. Guess I’m going to have to get used to sitting in a saddle again. I felt every pedal stroke. It seemed like an effort, more so than I remember. I guess my fitness really has dropped off. For some odd reason, my fingers would not recognise the fact I’m using a wahoo elemnt computer, and kept trying to use the button presses for a Garmin. I’ve not used a Garmin for years. Weird how muscle memory works.

And my old friend thigh pain hit again as I was climbing the small hill into Ripley. Well, I say thigh, it’s more hip than anything else. I’ve lowered the saddle from where I had it, so let’s see if that makes any difference. I hope so, because it’s a crippling pain.

You’ll notice the new See.sense Ace lights. I’m still waiting for a half decent Android app for these lights. It’s been a long long time in the process. Truth be told, I’m not overly impressed with them. But I guess that’s another story for a post I’ve been meaning to write for awhile.

On the way home, I was unfortunately reminded some people’s driving leaves a lot to be desired, with people pulling out of side streets, left hooks and close passes. But alas, I’m not surprised.

Still chasing a rattle

So, this rattle that I’ve been chasing, while slightly better with a different wheel, is still there under certain conditions.

However, I have an idea it could be the Wahoo mount I’ve been using. So, I’ve swapped it for the Garmin mount while I try and work out what it is. I have cranked down in the Puck bolts, but will first see what happens with the garmin mount.

  • Tried numerous times remove and clean headset
  • Replaced carbon expander bung
  • Replaced front wheel
  • Checked skewers
  • Replaced wheel bearings
  • Checked for visible cracks and damage

So, after a ride with just the garmin mounted, no noise. Nothing, not a damn rattle anywhere. I’ll give it a couple more rides to make sure, but it maybe cured.

So what is it about the mount I have for the Wahoo? Well, it could be a couple of things.

The Elemnt is a bigger unit, and heavy. So it could be moving, and hitting the handlebar clamp bolts as it sits very close to them. Which, I suppose could be the reason I went all out for a headset issue. Or it could of been the actual Puck on the mount being loose. I’ve really tightened them down. So if it does it after I refit, I’m likely to go down the route of it hitting the stem bolts.

The solution to that would obviously be a longer mount, like the k-edge. But I’m not really wanting to spend £50 on a mount.

Back to Garmin

I’ve been using a wahoo elemnt for a while now, and the Garmin 520 has Sat all forlorn on the shelf.

Today however saw it dusted off, and remounted after the elemnt mount broke. It’s a bit of a bad design. You can never have it just tight enough on the bar not to slip. Which meant I tightened it, only to pull the brass press fit screw thread out.

But going back to the garmin, made me realise that there is actually stuff I’d missed that the elemnt hasn’t got. And the opposite too. I missed some of the features of the Elemnt.

So, in no particular order here is what I miss when using the 520

  • Screen and font size. The elemnt screen is huge compared to the garmin, and easier to glance at to get the information quickly
  • Button location. The buttons on the garmin are awkward, and located oddly
  • Maps. Maps are a hell of alot easier and clearer on the elemnt.

That’s just what comes from the top of my head. I’m sure there’s more.

Things I miss when using the Elemnt

  • Recovery advisor, Vo2 and auto FTP. A small and insignificant feature set, but one I like to have.
  • Varia light control. I’ve got a full set of Varia lights which obviously don’t work with the Elemnt. Yet. With See.Sense working on their Ace light set, it might get supported.
  • Beeps and other bongs. The Elemnt is mute when compared to the 520, with a much smaller speaker.
  • Not having to correct speed spikes after autopause. Seriously wahoo, that’s annoying

Again, just off the top of my head.

But weighing up the pros and cons of each unit, it’s clear to me that the elemnt is the first computer I reach for when getting ready.

Elemnt Screens

Going around the various forums, one of the common questions I see, is “what fields should I have?” when setting up a GPS computer.

I’d previously done this type of post for my garmin so I’d thought I’d do one for the screens on my elemnt.

First Page

The first page is pretty much on screen most of the time. It contains all the critical information.

 

  1. W 5 sec, this simply shows my 5 second average power.
  2. KPH, is my current speed. I’ve found d myself looking at power more than speed recently, so speed is relegated to second field.
  3. BPM, current heart rate I have my heart rate zones displayed on the left hand LED display.
  4. RPM, my current cadence
  5. KM, Distance travelled
  6. Elevation, current elevation above sea-level.
  7. DEG-C current temperature

I don’t need much else on that screen. Using the zoom function on the elemnt, the 4 top items are the ones that are most important and on screen in a zoom state.

Climbing Screen

The climbing screen is pretty much the default. I think I just added RPM and BPM datafields.

There is the default Elevation display at the bottom of the screen.

 

 

 

 

 

Course Screen

2017-07-24 19.34.08

Similar to the Main screen, this screen shows all the important metrics, along with a KM to go display for the currently loaded course and a ride time display too. As the Elemnt lacks the timed course feature on the Garmin, we have to remember the time we are out to beat and do it manually.

First ride with Wahoo Elemnt

So, I’ve changed over from a Garmin 520 to a Wahoo Elemnt. And despite the missing vowel, it’s a worthy Garmin competitor.

Initially, I thought the LED’s where a little gimmick, but they are actually bloody useful. I’ve currently got mine set to display heart rate zone but have also used them for average speed, and found them useful for a quick reference point.

Screen wise, it’s a lot more readable in all conditions than the garmin, with better field presentation. Speaking of fields, setting up screens on the elemnt is stupidly easy. You just select the fields in the app, and drag and drop to were you want them on screen. Nothing could be easier. Non of this many button pressing garmin malarkey.

I’d replaced the maps on the garmin with open street maps from garmin.openstreetmap.nl which where miles better than the tosh you got preloaded. You can’t replace maps on the elemnt, however they are more than good enough to use as is.

All in all, a great bike GPS unit, and one that’s earned a place on my bike. Just a shame it dos’nt support my garmin lights. Yet.
