Re: Ultegra Wh-6700 Freehub

I have two sets of the old Spinergy Rev-X wheels, and from time to time replaced the original 6402 (Shimano 600?) freehub - which is very difficult to find anywhere. Many Shimano freehubs will fit the wheel 'spline', BUT, the problem for many(?) is that the locking bolt's 'lip' can (just!) interfere with the ball bearings - it's only subtle, but in time, this causes the freehub to loosen. So I took a chance with the Ultegra WH-6700 and it's been fine so far. The accompanying locking bolt appears to be different here - the lip of the bolt is flatter finished and so protrudes less into the ball bearing chamber. I hope SJS Cycles will be able to source another in time.

All these design variables are very annoying - but the cynic in me says it's all part of the marketing strategy.

I recommend this with caution.

Hi there,

The only suitable freehub is SJS Cycles part number : 29203

Could you please measure the height of this please?

I've tried one shimano freehub but it was too long so I couldn't put the cone locknut on. Many thanks, (I want this one as it's going on a spinergy wheel)
Hi there,

The length of the body is 38.1mm.

Compatibility With Dura Ace

Is this compatible with Dura Ace WH7850?

I'm afraid these freehub bodies use a slightly different to the fitting on your hub. The correct replacement for the hub on your wheels is SJSC part number 29201.
