Little known secret amongst riders, the manufacturers have gotten so bad at making the front forks level that the whole industry has used a workaround for it, if you use a DT Swiss regular hub on 50 percent of bikes in the front it'll bind, but the same dt Swiss branded hubs that come with the bike won't, why? Because the facing and width of the fork dropouts is not parallel, it causes binding in the hubs that have the bigger bearings and no integrated axle, instead they use front hubs with an axle included and the bearing sizes get much smaller and much weaker, but it stops the twist that lets wheels roll smoothly, it's good to look at in the stand but those bearings last 1/100th of the bigger versions, and they're much slower with weight on them.

The most useful tool in any workshop, the humble lathe. Rolf ni***es need to be a diameter of 4.6mm, regular internal ni***es are 6mm.

Original ni***es very hard to get, so make your own

Sorry sold out for his lifetime, look for second hand!!!

Unfortunately Dario has passed away recently, but his legacy lives on. Not sure about the wait list. These are the most beautiful bikes you will ever see. Also credited with the bikes built for Miguel Induráin under the Pinarello brand for multiple tour wins. In those days you only had to paint the decals on to tell frames apart.

Waiting period 4 years, by far the best builders and finishers in titanium or titanium/carbon mixed frames

What freewheel mechanism designs are used in bicycles? 25/05/2024

In short:

99 percent of hubs pawl mechanism, taken from a 200 year old idea, works well for most.

Dt swiss star ratchet, complete copy of chris king but simplified with two (now one) springs.

Chris King perfection, no one comes close to the design , stiffness and serviceability. Besides just the ratchet design the angular contact bearings, and needle bearing at the freehub puts them 2000 years ahead of the competition, making everything else look like it was designed by a child.

Sprag clutch (really?), where every manufacturer is chasing grams? also hard to service and they eventually slip

What freewheel mechanism designs are used in bicycles? What are the various freehub mechanism designs that have been designed and or put into production? (doesn't need to have been made necessarily!) A good post will contain: A description of the des...
