Campagnolo Chorus 12-speed Ergopower double road bike handles EP20-CH12C

I bought the entire Chorus 12v transmission set with a 32-48 crankset and an 11-34 cassette. I would like to congratulate Campagnolo for bringing to market a gear range that suits cyclists who do not have the power of professionals. The adjustment is critical and takes a bit of time, but as long as it is done well, everything works perfectly afterwards. A real plus is that you can use the same wheel as for an 11v system. I live on the edge of the Pyrenees and I find the twelfth cog an advantage with no drawbacks. The only downside was that upon receipt, there was an assembly fault with the left shift lever, the first time in 50 years that I found such a thing at Campa. Fortunately, with a bit of tinkering, I managed to solve the problem. That's why I took away one star. (Translated review)
