Here’s some material from winter group ride in Espoo. We didn’t anticipate that there would be so much snow, resulting in a very eventful ride as we mostly had skinny tires.
Last summer I managed to ride into a pretty severe OTB (over the bar), which resulted in a few weeks break from driving, buying knee and elbow protectors and the most severe of them all, a broken Reverb remote.
From outside I could tell that the remote had a bent piston and broken bushing. After the breakage, I could still use it a little on the rest of the ride, until it leaked too much and stopped working. The leakage resulted probably because the piston head was not perpendicular to the cylinder. Normally the bushing keeps the button level and guides the (straight) piston rod and centers it in the cylinder.
When I took the remote apart I also found that there were some scratches inside the cylinder, probably due to still using the remote after the initial breakage.
