Re: A curious Zefal HPX issue

Maybe that plastic piece in the chuck is oriented for Schrader and the valve is being jammed open.

Re: Measuring saddle Fore/Aft on Different Bikes

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...

Re: Quill stem to A head adapter frozen in steerer

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...

Re: Rim transplant: Spokes not the same note

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...

Re: Screw in Presta valves

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.

Re: Pinging or knocking heard from bottom bracket

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

Re: Orbea Gain D30 - broken spokes in rear wheel

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 ...

Re: Orbea Gain D30 - broken spokes in rear wheel

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.

Re: Regenerative braking on an e-bike.

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.

Recommended Cantilever Brakes

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 ...
