Ultegra/105 mix(6 posts)

Is it worth putting a Ultegra rear mech with 105 STI levers? Would I notice any improvement in the shifting over the 105 rear mech? And would this improvement be worth the extra $$$?

Put on Ultegra STI levers with a 105 rear derailleur and I think your shifting will be much improved (esp. over the long run) than the other way around. If you can, go for the Ultegra levers and rear der. outright. The Ultegra rear derailleur is only $12 more than the 105 at Excel, and the Ultegra STI levers are only $10 more w/o the Flite Deck compatibility. In the long run, you'll be much happier w/ the Ultegra.

I think the poster is suggesting an upgrade, not whether he should purchase one or the other.

There appears to be rather small weight and finish improvements between 105 and Ultegra. Really, how much difference could there be for $12? I doubt its worth the money to replace a functional 105 derailler with Ultegra. Just my opinion.

I've done this on occassion and you can't tell the difference from a performance standpoint. The Ultegra may be marginaly lighter and should last longer.

Why last longer?

You'll notice when you compare them side by side that they use better materials and incorpoarte better bearing designs in the pivots, even though the physical geometry/function is the same. Bearing wear eventually kills a der. - assuming you don't wipe out first due to "pilot error." ;-(
