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...

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 ...

I imagine it's pretty normal that if you are cycling above the legal limit you will feel an immediate slow down if you stop pedalling since you are no longer receiving power. That is not resistance. If there is no overrunning clutch in the motor, aren't you just "wasting" your human power...

As far as I know, only Brose and Fazua mid drive motors have no drag when pedaled with the power off, due to them having a freewheel clutch.

Can anyone recommend a heart rate monitor chest strap that works with an iPhone and the ebikemotion app?

it may not be possible to relace the hub; it is possible that the drillings may only work if the spokes are put in that way round. Even if it were possible I probably wouldn't bother. one reason is that when the wheel falls apart and you start thinking 'warranty?' it will be obvious that the wheel ...

I have an Orbea Gain ebike. The rear wheel is laced with all outbound spokes (32, 14 gage spokes). I thought that was a little odd. Is it worth relacing the wheels to the normal inbound-outbound pattern? Maybe spoke washers under the spoke heads? https://uploads.tapatalk-cdn.com/20190208/eb88f2bb39d...

Titanium Nitride is hard and also corrosion resistant.

The problem with coatings is that they eventually wear off.

I wouldn't worry about it. Keep an eye on it, but even if the tubing crack through the tube, it's not a catastrophic failure. I had a seat tube crack almost all the way around and the bike was still rideable before I noticed it.

I've got Mavic Yksilon Pro UST tires on my new bike. They came with tubes in them. I went to run them tubeless without sealant and they leaked. Dunked them in water and bubbles were coming out of the sidewalls so they require sealant. They are not the UST tires of yesteryear with the heavy butyl lin...

Brucey, I completely understand your comments about worn chains and I would like to clarify my original post. I should really had made it clear that I was drawing attention to the fact that the chain elongation tool has its uses but cannot indicate wear in all cases. I am going to quizz the owners ...

Many rims have bead retention humps in the rim bed. I think Mavic pioneered them in the original UST. That is what causes the snapping noise as the beads get pushed over the humps and snap into place. My Conti nontubeless tires make the snapping sound on my Shimano tubeless rims. A lot of rims don't...

Someone in that article discussion said to pump the tire up to 150% of the pressure you intend to use (no sealant and wear ear and eye protection). If the tire doesn't blow off, you're good to go. Seems that the tire bead could be damaged if it does blow off. What then? I think what's happening is t...

In this article, Jan Heine says not to exceed 60 psi in a tubeless tire: https://janheine.wordpress.com/2017/05/29/the-trouble-with-road-tubeless/ This is regardless of tire size. Panaracer also says the same thing for their GravelKing tires. (Panaracer makes Compass tires too.) This makes no sense ...
