Whats the verdict: strongest crank freehweel?

Post by 12-C » Aug 31 2020 8:31pm

I'm going to replace the freewheel since it's starting to act up a bit.

I'm considering the SBP UHD freewheel

Whats the verdict on durable freewheels?

The UHD SBP/White freewheel is definitely the best I've used. It combines the best of the regular White freewheel but with a second bearing to provide lateral support to hold the side loading introduced by a motor running into it.

All the single support bearing FWs, even the standard duty White Eno, eventually flog out without a secondary bearing for support.

Second best are the ACS Crossfires FWs that I believe have two bearings to transmit side loadings evenly. Sealing isn't as good as the White/SBP FW though

note that the SBP FW is slightly thicker than a regular FW because of the extra bearing, so you may need to adjust your chainline to suit

I have that one too. THere seems to be somethign wrong with it. There is a ton of play, with finger pressure it's almost like I can displace the bearings and make it "click" one side to the other....

I ended up ordering the UHD one... we'll see!
