I've been using a Pamir Hypercracker for years to install and remove lockrings. It's small and light enough to be carried around for trailside emergencies and means I don't need to buy a chain whip.

Now, I've just got a new Hope Pro II based wheel and the Hypercracker won't fit over the collar that the QR goes through the middle of. I think trying to drill out the inside of the Hypercracker probably would get messy, so I'm looking for a similar tool that would fit. I don't want to lug a chain whip around the countryside!

The few options I've seen on http://pardo.net/bike/pic/fail-029/index.html seem pricey for what they are or prone to fail, so is there anyone out there with a reliable cheap option? If I had the welding equipment I'd make one myself, but I don't. Any suggestions welcome. Cheers.

Not all of those homemade options need welding, although the ones that look easiest to make are not the prettiest. This one looks interesting though: http://www.hoogie.co.nz/info/hypercracker.htm

The other option is just to reduce the diameter of your drive-side spacer. That also is going to be difficult to do and leave it looking nice, but not impossible. Obviously being aluminium it's going to be easier to file down than the steel your hypercracker's made of.
