BB30 > BSA BB converter?

proto

Building up a new bike and want to use my old chainset (SRAM Force GXP BSA) but new frame is BB30. There are a number of converters that make this possible but are they all much of a muchness or are some better than others?

Is the Praxis better than the rest, or overkill?

You might want to risk one of the converters in order to save a few quid, but from what I've heard you're better getting something like this (I don't know if other manufacturers have similar products):

Rather than being an adapter it's a bottom bracket which fits bb30 while still being GXP/hollowtech/campag chainset compatible. Looks like a better solution to me, much less potential for something to go wrong/make horrible creaky noises/etc.

Praxis look like overkill - as heavy and expensive as Rolls. The Wheels Manufacturing delrin bushings have done me fine for 2 + years. http://www.merlincycles.com/wheels-manu ... tAodzB0AJw

They're all of 45 grams IIRC.

Not GXP compatible though, GXP has a star fitting on one side, without that the chainset will rattle around (I speak from experience )

By an amazing coincidence I'm at the Hope factory in the morning (Team WNTrace team launch). I'll see what advice they can offer.
