Switching from Ultegra to Rival. Do I need to change my FD?
 
Hey guys,

Quick question. I'm cross-grading from Ultegra to Rival. I've ordered shifters and a rear mech. Anyone know if my Ultegra Front Mech will be fine? Does Rival have the same front trim as Ultegra? I'm running a compact 50/30 crankset.

I'm running an Ultegra FD with Force shifters. Works fine.

I think the SRAM FD trims better than the Shimano stuff but other than that, works fine.

You realize that trim is controlled by the shifters, right? And that everyone in the world thinks that trim on SRAM road gruppos sucks?

Will work fine, derailleurs are 'slave devices' controlled by the shifters.......they have nothing to do with trim.

Actually, I don't think it sucks. I am running full Rival on a bike and honestly, I don't have to trim the FD at all in the big ring. There is no rub in the high or low gears in the big ring for me so it works as advertised.

The cage design could be different just like the new Dura Ace FD, chain and crank are ment to work with each other to result in no front trim.

While trim is controlled by the brifter, there are probably some differences in cable pull between the FD. I've never noticed because I've ran campy brifters with dura ace FD, Sram FD with shimano brifters and it all seems to work ok.

Uh.. no. I've got red shifters with force derailleurs, and I'm quite happy with the trim. Actually, it sets up so nicely that I never even need to use the trim anyway. I'm able to reach all of my cogs from the main click of each ring without any rubbing.

But thanks for speaking for me in a completely uninformed manner.

I use the trim. I dont really care what everyone else thinks.

And the derailers arent the same shape. The SRAM FD trims better on the small ring than the Shimano one does.

So does Rival trim in the small ring then?

Medpilot...how do you like the Sram shifters compared to Utegra levers?
Shifting? Ergos?
