In terms of function, the trimability of the front derailleur and the lack of springs and tabs that can gum up over time inside trigger shifters. And twisters just dont feel great to me on a long ride with a rigid fork. But also, I just love 'em… they have that nice “clunk” feel, kind of like older campy road shifters. And like a lot of other things, I use them as bait to draw out comments from people who love similar bikes to me
Thanks for the comment Mr stk101
Adali! yeah, she’s been going on the bike path recently. got a baby inside so has lost a little of her hellwoman attitude and is more comfortable giving hindmarsh a wide berth.
