Freehub splines compatibilty
I've bought the eldest a 2008-09 Boardman Pro road bike. It's got a ten speed cassette on it and I've tried to put the ten speed Ultegra 14-25 race cassette on it. However the splines on the Ritchey free hub are too deep for the Ultegra cassette (they have a step part way down). It's all Shimano.
Can any one shed any light?

The only explanation I can think of is tat the freehub is a dedicated Shimano Dura Ace 10 speed freehub which has deeper splines.
A regular cassette may destroy the freehub.0 -
Have a read at this article. Towards the bottom of the page it describes and shows pics of the "10-speed only" freehub. This was introduced a few years ago but was subsequently dropped. It had a different spline profile from the standard 9/10 speed now in use.

You might be able to source a 9/10 speed freehub body for the wheelset but that could be relatively expensive or impossible to source. Might be a new wheelset or rear wheel needed.0 -
Yes that's the hub that is on it. I need a 9/10 speed freehub for Ritchey wheels then. Any Ideas?0

You need to first identify which freehub design you have - there are several.
Have a look at this web page

Towards the bottom on the RHS there is a clickable link to a PDF file entitled Hub ID PDF.
Download that and check out the pics against the freehub on your wheels. Hopefully you can then search for the correct 9/10 speed replacement. Winstanley Bikes seems to carry Ritchey spares-give them a call.0 -
Are you the guy I've seen somewhere else saying that you'd found the issue was that the Ultegra Juniors 14-25 cassette has shorter spline grooves like a 8-9sp cassette, rather than the usual deeper 10sp grooves ?
If not, someone else is having the same issue !0
