Although those sorts of bikes normally mount 700c, those particular wheels certainly look 29" to me. So the gargantuan 622mm rims not those wimpy 622mm rims? While they have the same diameter a 29er rim is wider. 27.5" rims have the same diameter as a 650b but again they are wider to mount up to 42 mm wide tires. |

I enjoy them a lot and the conversion wasn't expensive. Cost wise it sure beats buying a new dedicated gravel bike. Cheers You are right, the gravel bikes are expensive. About how much was the conversion? Andy Not much. I had most of the parts here or on another bike I was converting to something else. Bar-end shifters, Shimano Brifters, or Campagnolo Ergos work really well. I liked the Ergos at first because the brake lever was solid and the cables went under the bar tape. I see that Shimano changed to that routing too. Cheers |

Peruse these: https://duckduckgo.com/?q=broken+der...es&ia =images The most common failure being "merge with spokes". I've seen such things in real life. On two different occasions, I fixed similar problems for other riders so they could finish their rides, with perhaps fewer gears than they had at the start. But that sort of failure can happen anywhere if the derailleur is adjusted badly enough. It doesn't have anything to do with gravel riding. I wondered if Russel's derailleur tried to swallow a rock. -- - Frank Krygowski |

I replaced it with another new 105 long cage rear derailleur and the shifting works perfectly again. It happened a few months ago so I cannot remember exactly what happened. But shifting was bad, not precise, move the STI one click and the derailleur did not shift the chain. Move it two or three clicks and it would sort of move the chain. Everything imprecise. New derailleur, no change to cable, and everything shifts perfectly again. So I am pretty sure it was the derailleur, not the cable or shifters. Perfect shifting for several years before the one gravel ride. End of gravel ride bad shifting. New derailleur perfect shifting again with no other changes. So I assume the 20 miles of gravel riding killed the derailleur somehow. |

What could have happened is a cracked pulley cage plate (inner or outer). My brother had that once causing also weird shifting. Replacing the cracked outer cage plate was less than 10 euro: https://www.bike-components.de/en/Sh...8-grey-GS-type Lou |
