PowerTap freehub cassette removal
I've got a PowerTap 2.4 SL with Shimano groupset. The first time I removed the cassette, I noticed that the splines on the freehub body had become notched by the individual cogs of the 105 cassette. This seems to be a common problem with the aluminium alloy freehub body. To combat this, I filed down the notches, and got some pins from American Classics, to hold the cogs together.
It's now been quite a while since I did this, but I've now come to try and change the cassette and I can't get the cassette off - it seems to be completely stuck. So I guess the pins haven't really helped, and now the cogs are probably well dug into the freehub body.
Anyone got any tips for getting the cassette off? Leveraging with a flat head screwdriver hasn't done the trick.

I took mine into LBS the first time this happened - a vice and a rubber mallet seemed to do the trick. Last time I did a DIY bodge job - held the smallest cog with a chainwhip and tapped each of the cogs with a hammer. The (gentle) tapping seemed to be enough to loosen the cassette off the splines of the freehub. Don't overdo it...!0

Thanks for the advice. I might just leave it to the LBS as I've asked them to order a steel freehub body as a replacement.Le Blaireau (1)0
