I’m suprised no manufacturer has used bolts and nuts on an alu frame to save on thread wear. I’ve never had a problem with wear mind but having a hexagonal cutout (frame side) on the bearing cup to slip in a hex nut (so it won’t spin) would fix any issues people are having.
Sounds a bit short to me if no defects. For Al I’ve heard up to two years if ridden hard. Week spot is usually just above the crown, several have gotten theirs rewelded. Never heard of steel Nimbus’ braking.
Any other news of QR bearing holders on the grapevine?
The Nimbus could be straightened and the others possibly rewelded. Might as well reinforce while at it if you take either route.
Only break I’ve seen on KH frames is the neck breaking off the crown. If u still have them take the pieces to a welder and have him put them back together. Newer KH frames are reinforced, 2011+ I think.
