Insight needed: Any option to get a 46/30 Chainring compatible to SRW 12? Or SRW12 Compatible crankset?
Folks, I have a luxury/1st world issue: my son (U15-regulated Racer) is going to get my SRW12 on his new bike (as I, mamil-dad 😉) has now an excuse to upgrade to SRW13 (thumb shifters are so back)...
Issue is the UCI/German Cycling drivetrain regulation for U15 (which he has to follow until end of year).
The Campa-Native solution would be to use 45/29ers, but that would leave ~15cm per full turn wasted, and that is something in 35km Crit/Road-Races.
Custom Chainrings are mainly only Chimpanso/Scam compatible (at least i see it) and also the FSA option from back-in-the-days is C/S only, but with 46/30 he would be 100% on top of the regulation.
Anyone has some idea on how to solve this riddle in a cost effective way? Next year with U17, its 50/39 galore and no issue at all
