GPS tech (Garmin, Hammerhead, Wahoo, RWGPS, etc)

Yeh. Also when I am whacked I can't keep warm. So it's interesting to know if it's actually cold, or its 15degrees and my body is just a mess

Interesting. My 1000 always seemed pretty accurate.

Yeah, because I don't use my etrex much (at all really, it's just a backup) I never even noticed it didn't have Temp on it. Just assumed it was there. The Edge units all seem to record it reasonably well.

Since going fixed route and off road etrex has become the best device.

Yeah, the turn by turn I use a lot on the road would be useless off road. I'll probably still take the Edge for Badlands because it seems most of the gravel tracks are marked/obvious, it's not MTBing. etrex will be packed as a backup though.

yeah, it is, but when you get off the train and it is 3 degC, the edge needs around 20 minutes to acquire that ambient temperature. whereas the tempe sensor needs 3-5 minutes. it is not that important, but i find it nice.

Wait, are edge models crap for mountain biking then?

I don't really mountain bike so I'm the wrong person to ask. They're more expensive, possible less durable with the big screens and things like turn by turn are pointless so etrex start to make more sense on the dirt.

Really? My edge 1000 will go from indoor to outdoor temp in minutes.

I like to have the route up all the time, when it's fixed route you can't mess it up or your possibly DQ. Plus the AA batteries mean I don't need to worry about charging, and given that a dynamo does not work so well off-road it is a headache removed. Also I stopped using power racing off road really, as it means less, so that removed my need for an edge.

No they are just fine for MTB. But I have weird demands which an Etrex meets better.

I typically have the route up all the time, because I take wrong turns so often it helps get on route quick. I probably won't have dyno wheel for Badlands, I'll just take battery packs. If I do more I might get a 650B dyno wheel built, but I get that it's less use off-road, especially at my climbing speed! :S
I considered ditching the PM last year because I was struggling to find sub-compact cranks but I like the data too much.

I like data. But my PM keeps dying off road, so I will give up on it for a bit. Plus I know what it will say now anyway, so it's a bit redundant.
I considered no dynamo for Atlas, but having a dynamo front light is good and it means I don't need to worry about lights so much. I will take a battery light too. Lights are a big one, no light and you're not going anywhere.

Yeah, I stop looking at mine after day 1 and don't care what my power is nowadays during ultras. I can't get any lower than it was during the first TransAm anyway :)
If I didn't already have a working set of non-dyno wheels I'd definitely build a dyno set but because I've already got the set I don't really want to rebuild the front, nor do I want yet another spare wheel in my flat.

My edge 1000 will go from indoor to outdoor temp in minutes.

that was definitely an issue with 820. i have now 530 lying around, but haven't tested it that way.

Not really a gps question but can anyone suggest me a cheap computer that uses ant+ garmin style speed and cadence sesnors?

I'm tempted to get a Garmin Edge 25 from SportPursuit but then I'll be another £30 or so to add the sensors (computer would mainly be used outdoor but I would like to be able to use it to keep track of the little bit of track riding I do as well).

Someone in the non-ebay bargains thread mentioned that the Edge 25 doesn't record altitude/elevation, if I recorded a ride on the Garmin then put it into Strava would Strava apply its own elevation stats to it?

Yeah. My previous Garmin was a 705 which didn't have an altimeter. Still get elevation in Strava.

Edit - Appears I was wrong and the 705 did have an altimeter. There is however an option in Strava to calculate it based on their elevation data for your route.

My Edge 25 measures elevation. I think it's GPS estimate rather than in built altimeter, but it is possible to have it on the display. Strava will make it's own calculation for elevation and distance anyway unless you override it. IMO, Speed sensors are a bit pointless. GPS calculated speed should be good enough for pretty much everything you'll need. It's a bit jumpy on twisty descents, but you don't really want to be staring at your Garmin at that point anyway.

Except the indoor track riding he mentions he'd want the speed/cadence sensor for.

@Brun good to know cheers.

@chiroshi it was just for indoor track that I thought I’d need the speed sensor. I’d maybe use the cadence one out and about but I just like to know what peak cadence I’ve hit after a road ride and as I ride fixed it’s easy enough to work out from my speed.

Ah missed the indoor track bit, sorry.

There's a cracking deal on the 820 bundle on wiggle, can anyone share their experiences on how much of a dud it is? I'm struggling to justify nearly double the cost for on unit routing and climb Pro of the 830 when it'll mainly just be used for training intervals and following breadcrumb grx routes for now. I heard some bad things about the touchscreen being really crap, did they fix that at all?

what's the deal?

If you only want intervals and breadcrums a wahoo might be best

I heard some bad things about the touchscreen being really crap, did they fix that at all?

Not really, no. There's a reason why they're still knocking out the 820s at significant discounts so long after the 830 was released. The prices are tempting, but in my book it's a temptation still worth resisting.

Thanks, this is exactly the kind of pragmatic opinion I need! I'll have to keep saving for an 830 or Fenix.
