Bying new groupset- Ultegra 10 speed 52/36
Postby andrich » Mon May 09, 2016 2:46 pm
I have a Giant TCR Advanced SL and currently run Ultegra 10 speed groupset.
I am looking to go from the current 53/39 to a semi-compact 52/36, however this requires me to go to the 11 speed 6800 Ultegra set.
I have a couple of questions.
-If i am currently running the 10 speed set up if i buy the 6800 11 speed set up below is that all i require to do the change? is that a good price?

-What size and style BB do i need? i think its English but im not 100% sure
-Is there anything i can keep from my 10 speed setup that is compatible or is it just the brakes?
- What would a second hand Ultegra 10 speed groupset be worth? 53/39, 11-28 cassette. All in good condition with a couple of grazes but functions perfectly
thanks for answering the questions
cheers
Michael

This is absolutely spot-on.2wheels_mond wrote:You don't need a whole new group, just a new crankset. The Ultegra 6800 will work fine with everything else, and you don't even need to change bottom brackets

Is the performance compromised at all in terms of shifting or anything?

Kept my Sram S900 10s cranks 53/39 and changed front and rear derailleurs, shifters and cassette to ultegra 6800 11s. No probs.
The 6800 does shift with a lighter action than 6700 and with a GS or mid cage rear derailleur you can run a 32t rear cassette. Not sure if the SS short cage derailleur does or not, shimano doesn't list it as doing so? So I got the GS.

However, a K-Edge drop stopper has cured all my ills. I haven't dropped a chain since. It's as good as the 2x10 on my mountain bike with the clutch rear derailleur.

I can tell you with absolute certainty that the short cage derailleur will do it, but when paired with a wide-range double (i.e. compact or mid-compact with 16T chainring difference) it does push the derailleur very close to the limit of the chain wrap it can handle, which is why Shimano only recommend the 30T with it. The upper body which determines the sprocket clearance is the same for both versions, so there's no reason why you can't use the standard derailleur with the 32T when paired to a tighter-range chainring pair.warthog1 wrote:Not sure if the SS short cage derailleur does or not, shimano doesn't list it as doing so.
That could be more to do with being a different brand crank than the 10/11-sp. thing. Shimano's later cranks (2nd-gen 10-sp onward) have wider chainring spacing than most others, so the derailleur swing is calibrated to match. Setting up on closer-spaced rings can be a little bit troublesome.trailgumby wrote:I'm running 11-speed Rotor 3D+ cranks on Ultegra 6700 everything else and I have found it is prone to dropping the chain off the inside a lot. Probably once every 100km. Quite annoying.

Incidentally I dropped the chain with the K-Edge drop stopper for the first time tonight, on the way home. I had a bus up my ass, which wasn't fun, but I think it was user error. I'd had a close passer shave my elbow not long before so was a little distracted and probably didn;t complete the downshift properly before coming to rest at the traffic lights.

Now I have to decide whether to go a 11-28 or 11-32 cassette with the 52/36 rings.
Is the 32 only really necessary for big hills? I did the orange Newcrest ride this year with my 52/39 and 11-28. The couple of steep hills there nearly got me but I managed.
I am hoping to work towards the 3 peaks challenge in the coming years. Would I be better served with the 32 or would the 28 suffice? I am reasonably strong but a heavy rider.
It may sound silly (as it probably does fit) but can someone just 100% confirm that this setup with be compatible with my tcr. I just wanna make sure before I purchase.
My wheels are 10/11 speed compatible so no issues there.
Thanks in advance
Cheers

Use the 28-11 for regular duties and bung the 32-11 on for the big hills. The 32 is really just a bail out gear which is good to have there in case.
Cassettes wear anyway so it doesn't hurt to lash out on another when you can afford it.
I run the 28-11 normally and save the 32 for steep long days.
You wont regret going 11 speed, the shifting is nicer than 10s

But I reckon 11-32 is on balance a "safer" choice as you only miss one of the heavier gears (15T I think) but you gain the 32 which makes up for the lost 15T easily. For me, if the gradient hits around 10 and the climb is 5 min or more, I'm sure to be using my 32T.

After much consideration i ended up going the 52/36 11 speed with 11-28.
I had it installed on friday and have done 100km since.
IT IS AWESOME.
Well worth the money and i would recommend anyone who is thinking of upgrading to stop thinking and do it.
Shifting is so light and precise, love the gearing and the brakes are a big improvement over the 6700.
thanks again
