Now, on to the topic of gearing. The original is a 10-speed cassette with 11 on the small gear and 25 on the large gear (I didn't bother counting teeth on the gears in between). For the spare wheel, I think I probably want 30(?) on the large gear. I imagine this should get me noticeable improvement on my hill climbing ability. And then if I only go up to 12 teeth on the small gear, I don't imagine that would make a huge impact on the top end. But I haven't even started shopping yet, so not sure what's available to me.
As for the RD, the only thing I saw on it was "Red". I don't know if that's their model or what. I didn't see any model number, but not sure where to look either.
Yes, Red is name of the group. There are different model years that may have various options, (short or mid cage length).
Post a pic of the RD and hopefully someone here will ID and know the max tooth count and total chain take-up capacity.
Also provide chainring tooth count so we know how much chain take-up is needed.
Depending on the current chain length, a longer chain may be needed. Maybe post a pic of the RD while in the big ring and biggest sprocket.
At least the cassette fits on the freehub, that's a good start.
