Ultegra rear Derailleur
Postby Snoopy007 » Sat Aug 25, 2012 9:22 pm
I've heard that some people have certain groupsets e.g shimano 105, but have bought a high "class" derailleur (e.g ultegra), and asked their lbs to put it on for them. Being new to cycling, i haven't actually bought my first road bike yet, but i plan on getting a 2012 Reid falco with the 200$ upgrade that adds the mavics, yes i know ive been posting about them recently, but anyway i'd like to know, would buying a Ultegra rear Derailleur (about 100$) and asking my LBS to put it on (this bike has a 105 groupset), will it have a difference in performance, if so how, and what do derailleurs actually do? =S sorry for the newbie questions, but im still pretty new.
Cheers

Like i said, because i heard some people saying they upgraded there's so i thought it might make a difference.. you could just be nice and help me out =PLazyweek wrote:I hate to be mean but if you don't know what derailleurs do, why do you need to upgrade it? My road bike has 105 and it does the job.

BTW, the derailleurs are used to change gears.

I'd save the money and spend it on other more worthwhile accessories (lights, pump etc..) or to pay for a cycling membership which offers cycle insurance.
As for what the derailleur does - it guides the chain onto the relevant sprocket (gear) on the rear wheel.
As you change gears from the shifters on the handle bars, the tension increases or decreases in the cable running to the derailleur which in turn adjusts the derailleur and the chain moves up or down to the next gear.
You also have a front derailleur which does the same thing but moves the chain between the chain rings that are attached to your right crank arm.
Just a tip: after a couple of hundred km's on your new bike (once you buy it), the cables will stretch and the gear changes won't be as smooth. This means it's time to return to your local bike shop (LBS) for it's first service, in which they should adjust the cabling so you have smooth gear changes again.

NO. Not worth the money. 105 gear is perfectly fine to begin with.
Once you've ridden it halfway into the ground and discovered you really like this bike riding thing is the time to consider upgrades (but chances are, by then, it'll be the whole bike you want to upgrade )
As Dave said, spend the money on the little extras.

IF you're not going hard, you probably won't notice a significant difference. If you are going hard, you will be in so much pain that you won't notice a significant difference!

The good thing is that 105 is fine and you don't need to upgrade:)

Listen to this man - he speaks sense!warthog1 wrote:The rear deraileur just does what the cable tells it to and the cable does what the shifter tells it. Probably more to be gained in feel from upgrading the shifters, which is more expensive unfortunately.

A RD 'above' the rest of the gruppo is really all about the bling, but the RD, as warthog1 hath spake, is just a dumb thing that goes where the controls tell it to go.
