Re: E-motion app for Orbea Gain

I've found the app unreliable and annoying at times, but the recent updates seem to have resolved some of the problems, though the cadence and ascent figures (230 rpm, and -168% on recent ride) don't make much sense to me. It also cuts out sometimes for no reason. I use it all the time, I don't use...

Re: Preventing spokes unwinding

There is wicking Loctite (expensive) that I would recommend using. More tension is not the answer, assuming that the spokes are already at the tension recommended by the rim manufacturer; rim cracking will result. Large variations in spoke tensions can cause the loose ones to unwind, so balance the ...

Re: E-motion app for Orbea Gain

I stopped using the app and mounting the phone on my stem. It was useful in understanding how the bike works, but now that I understand that, it's not too important. My Garmin is more accurate anyway.

Re: E-motion app for Orbea Gain

Having an external battery for your phone makes sense when using the app. I have one made by Topeak that mounts under the stem. I had no trouble downloading a map.

Re: Portable Charger External Battery Power Bank Reccomendations?

Do you want one that mounts on the bike? Topeak makes one, but it's pricey.

Re: Vulcanising solution mystery

Jobst Brandt said that the reason the solvent evaporates from the tubes is that the seam on the tube is crimped, not welded.

Re: OBREA GAIN D40 (e-bike)

I've had a lot of problems with the app, (since mid 2018), but after the 2 most recent updates it now seems to be connecting OK and giving accurate information. Some features are no longer on screen, such as gradient, replaced by 'pace'. Distance covered is much more accurate now too. The app is mu...

Re: Bar end shifter compatibility please.

My Shimano 10s barends are index only for the rear derailleur.

Re: Recommend drop bar STI shifters and 700cc wheels with <20 gear inches setups

For that setup I use sub-compact double cranks, and SRAM rather than Shimano shifter/derailleur, as SRAM have maintained (at least for 11-speed cassettes) compatibility between Road shifters and MTB derailleurs, so you don't have to use any cable pull adapters or device such as a Roadlink to move a...

Re: A question for Orbea Gain riders.

I've ridden my Gain a max of 38 miles, but have no doubt it would go at least 50 miles when ridden in eco mode. The Gain has a 250 watt motor, same as many mid drives. The bike is lighter and I think it's more efficient than many others, which means you get more out of that 250 watt battery. They a...

Re: Drop bars - who uses the drop bit?

If you raise your bar height, you'll use the drops more; maybe the tops of the bars level with the saddle.

Re: OBREA GAIN D40 (e-bike)

I bought a carbon Gain M30 a few weeks ago. I live in the US so it has the 20 mph cut-off speed, and I've put 275 miles on it thus far. I love it. I haven't used the app except to check the power level at the end of the ride. I just ordered a Topeak bar mount for my iPhone. Does the bike increase t...

Re: brinelling

actually I think most of what rogerzilla has said is what I've said, not what Brandt has said. Its been a while since I have read what Brandt said in detail but IIRC he maintained that it couldn't possibly be real brinelling because the loads would be too low for that to happen and he couldn't see ...
