@cyfa2809: I am a fan of the modularity of the bicycle, but here it was a decision to go for another level of
modularity. It is a very true point that it will make replacing parts, when broken, more expensive. However
I tried to keep the 'wear' parts standard; it still has some shimano parts underneath but with their own
'jacket'. The idea is that these 'jackets' won't wear, only the standard parts.
@ stevet1: that was actually one of the difficult decisions. A small bridge would structurally be better, but
messes up the lines.
@ bwhsh8r: that's great. thanks. I do speak english, but those details in grammar you can never learn as
a foreigner.
