This was written by frame builder Dave Kirk: Most of us have more than one bike and I often hear from riders who say that they have a hard time getting two bikes to have the same exact contact points. The three contact points, and how they relate to one another, are what determine how one sits on th...

Lots of heat to clamp area to expand it via plumbers butane torch or hot air gun, remove 2 clamp bolts and use a flat blade screwdriver cautiously to spread the gap in the clamping area, while trying to twist bars? just an idea. Heat won't work because aluminum has a higher coefficient of expansion...

I think it's impossible to have a straight wheel with no tension variations among spokes. What you want are no large tension variations (like larger than one note difference). Balance tensions by loosening a tight spoke between two lower tensioned ones by loosening the tight one and tightening the l...

Removable valve cores are great if you want to inject sealant in your tubes or use tubeless. Lezyne says to use a drop of Loctite on the threads of the valve core to keep it from unscrewing. All my pumps are push on and thumb lock, so I don't have the problem. Most tubes don't have replaceable valve...

Am I right in thinking the hole is larger to accommodate a tubeless valve?

Do tubeless valves need a larger hole? I don't think they do.

I find that the bottom bracket gets most often blamed for creaks, but the problem is elsewhere.

https://uploads.tapatalk-cdn.com/20190705/23b9c6a31e99af108a8d38ab38fa826f.jpg It looks to me that the spoke elbow length is a bit long and would probably help if spoke washers were used. Also, I don't like the fact that all the spokes are outbound. I also noticed moderate tension variations among ...

I've got a bit of miles on my Gain and haven't had spoke problems. I stress relieved the rear wheel, maybe that's why.

Some folks on the electric bike review.com forum that have used regenerative braking say it doesn't work that well because, on a bike, you are just not using the brake enough to make it worthwhile.

How are those suntour se rear brakes? Are they noticeably grabby or anything? I have a feeling I might still have a set squirreled away somewhere. Sjs have been offloading cheap for years. I used to use them on my old mountain bike, along with a Scott SE brake for the front. I switched to Diacompe ...

V brakes can be a cure for fork judder, if you have that problem.

That Fix spoke prep on the Wheel Fanaytic website looks pretty good. I think I'll buy some when I build my next wheel. I've got some old Wheelsmith Spoke Prep but it's pretty old and may hardened up by now.

An relevant article on the Wheel Fanatyk website https://www.wheelfanatyk.com/blog/fix-for-spoke-threads/# Roger Musson, in his book, recommends Loctite 222, applied after initial lacing of the wheel on exposed threads and give the wheel a spin to force it into the threads. It starts curing in 30 mi...
