Review on SHIMANO Claris R2030 8Spd Triple Front Derailleur Adapter: 34.9mm, Compatible with 31.8/28.6 Frames by Kipp Amundson

This derailleur is much better designed than SORA. Sora broke the spring tab on two different wheels. It's hard or impossible to find Sora, but that's okay because I don't want one like that ever again. It seems to work better in both 8/3 gear and 7/3 gear. It has a fairly wide cage. So if you have micro adjustment or "1/2 step" levers you can adjust each cage contact. This one doesn't have an opening cage, so you'll have to break the chain to put it on.
