Challenge Furai Chain Guard (for M8 bolt)

Note: unlike the M5 version, this guard has not yet been prototyped, however the only difference is the size of the bolt hole. It might be necessary for me to slightly change the design if it turns out the fit is not perfect. This will be done in close collaboration with you and shapeways.

Chain guard for a Challenge Furai recumbent bike (and possibly other challenge bikes). No more greasy pants.

This version uses an M8 bolt. 

You'll need to get a stainless steel bolt that is 5 mm longer than the orginal one to fit this to your bike.
