When my Silver1 shifter broke and I replaced it with a Suntour Barcon. I was surprised by how easier it was to shift to the last cog on a 10 speed cassette compared to the Silver1 shifter. My initial set-up with the Silver1 shifter was with a Deore XT 10-speed derailleur. The last cog was almost impossible to shift and sometimes didn't. I replaced the Deore Xt with a Claris 9-speed derailleur and that fixed the problem. However, I had to swing the Silver1 shifter all the way up to get to the last cog. It is now easier with Suntour Barcon. I sometimes wonder why a bicycle company hasn't come out with a modern version of the Suntour Barcon....
