You might well be knackered I’m afraid. The Jumping Flea that I had was a ‘sealed unit.’with a tapered roller bearing at one end and very small captive cartridge unit at the other. Such is the apparent confidence of Sun Ringle that their Freehubs will run and run. Aye, in California maybe…
I went through 2 in 6 months of Scottish riding – albeit warrantied by CRC. On the third occasion I invited them to replace it with something which worked. To their credit I got a Hope unit. The Freehub was also circa £90 to replace iirc.
Needless to say I’m not a fan of SR. I hope you fair better.
