What does trim (or no trim) on a Front der. mean? - Page 2

Okay, "I hear you" ... but, you must have really long fingers OR large hands if you can reach the levers when your hand is positioned close to the junction of the handlebars & brakes ...

I guess it just never occurs to me to have my hands where-or-how I presume you must be placing yours ...

Well, you could be right ... but, form follows function ...

One could ask: WHY DO SHIMANO SHIFTERS WEIGH SO MUCH (if they are so up-to-date)?

Since I haven't used a SORA shifter, I would say that if the SORA shifter doesn't work any better than the OTHER Shimano shifters (e.g., Ultegra 6500), then I might possibly agree ... but, maybe not!?!

Good info from everyone. Not sure where the OP read about no trim function, maybe it was a miscommunication as many SRAM users were complaining about no-trim in the big chainring with Rival and Force (not to be confused by no trim at all) which was then addressed/updated with the Red shifters. Rival and Force are capable of trimming in the small chainring, while Red is capable of trimming in the large chainring.

I have a bike with relatively short chainstays, so the chain angle is slightly larger in the extreme high and low gears compared to a bike with longer chainstays. My bike has rival shifters and I have to trim out in the small ring in top 3 high gears (read: 3 physically smallest gears on the cassette) No trim in the big ring for me, but I never cross chain with the big-big combos anyways, otherwise I'd just shift back into the small ring.
