If I go the 9-speed route with one less cog, how do I keep a 9-speed shifter from shifting the chain off? Will the RD limit stops stop shifting at the 8th cog?
Also, I read nothing good about Sora, so probably do not want to go that route.
Here's a pic. Ain't she sweet. Just the ticket for my 5'1" tall daughter.
Thanks.
Sora shifters work and don't cost a bundle. Don't be blinded by BS.The freehub body for 7 speed HG cassette is about 4.5mm narrower than an 8 speed hub body.. 8 speed uses 130 dropout spacing. 7 speed dropout spacing was typically 126,but many later ones were made with the compromise 128 spacing....Ya block the shift with the low limit screw....Don't be surprised if the TT is too long. A 50 just doesn't fly well with 700c wheels.
