i made a bag like that, for a much bigger triangle, and what i found was that the battery didn't stay snug up against the toptube like i'd hoped... :lol: instead gravity pulled it down and wanted to shape it like a tear drop (if viewed like cross section)...
if you have a hard liner between the bag and the shock that will help, but i'm guessing the shock action will eventually tear the fabric at the least and rub whatever is inside if they stay in contact like shown in your photo...
anyway, i'm really tempted to get one of these frames. so i've been researching them a bit:
i think
hodaka is the parent company and they show the (more recent?)
CFD 2500. (the 2500 has symmetrical chain-stays unlike the 2000 - an afterthought for the chain, that they corrected in the 2500, i wonder?)
The site is copyrighted 2001
, but the chronology goes to 2005. Looks like they've been building
aluminum/scandium frames since 2001.
Can you measure the narrowest part in the rear triangle? How big of a tire will fit? 2.5"?
