I would highly suggest a spoke guard inside the cassette (dork disc?) for FWD where you could hit the RD with your foot if at all possible. Funny story as I rode my bike to get just that item
I had the limit screws set but I somehow knocked it at some point on my ride. Later going down a hill at about 25 I shifted the wrong way and the chain took a dive into my cassette. I was able to instantly get both my feet unclipped but having the front wheel lockup and lose all the spokes on the right side is an interesting experience.
One spoke actually held off on the cassette side but the other 15 were torn very quickly. The baron came up a few minutes later so at least Mark got to see the new cruzbike frame.
Not really sure what the plan is. I think the hub might be toast or at least the freewheel and/or cassette along with the rear derailleur. Might be time for the internal hub I was thinking about.
Edit: actually.. I guess it is time to just hang it up for a while.. maybe revisit it later or sell outthe cruzbike parts as a kit or something.
