My CX bike had a creak which became ever louder when I stood on the pedals (up hills, sprinting).The eventual solution? Clean all dirt off the rear dropouts and skewer. Then smear grease on the…Continue

"I had TRP Hylex on for a season and a half. Front pads replaced with sintered (from a place in the UK) and the rear left with the red TRP OEM. Just noticed after the season turned wet (in NorCal) that there is quite a bit of wear on the pads now.…"

"There are several groups that train in Woodland Park August-November. There are many good routes around the park with lots of offroad, runups, etc. The Greenwood area has many gravel alleys that I like to do sprints through. There's a 1km…"

Geoffrey Grosenbach replied to Erik Annis's discussion Van Dessel: Gin & Trombones
"My first bike was a G&T and now I have a custom frame from a local builder. My limited experience is that the G&T is a fast dry conditions bike. The steep seat tube angle puts your weight over the front wheel and is hard to handle in the…"

Fixing that creak

My CX bike had a creak which became ever louder when I stood on the pedals (up hills, sprinting).The eventual solution? Clean all dirt off the rear dropouts and skewer. Then smear grease on the skewer and also the inside and outside faces of the rear dropouts on the frame.For now, the Principle of Silence is being observed properly and I can ride in peace.See More

Geoffrey Grosenbach replied to david taylor's discussion neutral support questions
"They would definitely have an air pump. I suggest bringing your own kit with extra sealant. I put some CX tires on an old heavy set of wheels that I use as a backup. You might consider buying an extra pair of disc wheels if you're worried…"

Geoffrey Grosenbach replied to Chilton Powell's discussion Pad clearance on TRP CX 8.4
"I took a disc-equipped bike and retrofitted it to use TRP 8.4s. No regrets...a great brake. I ran them a bit loose in muddy races but they clean quickly after one rotation of the wheel. I wouldn't worry about clearance unless you notice…"
