Rated 4.9 out of 5 by 10 reviewers.
Rated 5 out of 5 by Brilliant! I love this groupset. The gear shift is so smooth and fast. It looks great and feels great. It's a reasonable price and is quick and easy to fit and install. My only niggle is that the front derailleur is very narrow, however with a little fine tuning it's not really an issue. 25 May 2014
Rated 5 out of 5 by Excellent groupset, super fast delivery by CRC! Buy buy buy! Can't go wrong with this groupset. No regrets! Super smooth shifting and lighter than previous 10 speed 6700. 04 May 2014
Rated 4 out of 5 by Worthy upgrade I tried from a 9 spd(sora) to a 10 spd(105) to my ultegra 6800 It works great, good shifting. II am even able to shift under load when I go uphill, and it doesn't give a clunky sound like my 105. Not to mention, the aesthetics, it look great. The shifters beats the 105 with its sleek designing The brakes work great also,responds really. My only thing is the chainset. Well, compare to the dura ace, the ultegra groupset seems like it has a little more to upgrade on its aesthetic, but other than that it works fine Lastly, the price range is so affordable, at 11 spd, and it is at only 450 pounds? Its a worthy buy compared to the other brands of groupset. Can't ever go wrong with shimanos 01 May 2014
Rated 5 out of 5 by Believe the hype, it really is that good Everything is better than before. Braking, rear shifting, front shifting (this is properly good), cables, hood comfort, everything Even the ability to change chainrings to any combination using the same BCD is brilliant. Why has no one done this before I wonder? Can't fault it. And for the price I paid (£430) it is outstanding value 25 April 2014
Rated 5 out of 5 by Shifting is superb Well ive been using Shimano 600 and then ultegra all the way through the range, thought Id finish on 6700, however for £405 for the full G/S couldnt say no, Shifting is even better than 6700 and its a smooth ride Fully recommend 13 April 2014
Rated 5 out of 5 by Très bon groupe Super deal, très bon groupe pour la route. Facile a installer sur un vélo. Complet 12 April 2014
Rated 5 out of 5 by Most impressive. I bought this group set to fix onto a new bike that I was assembling so I got to know all of the parts quite well. The quality of the materials appears good and even though I am not the biggest fan of the dark grey colour the group set looks good now that everything is in place on a titanium frame. Highlights for me include; easy, snappy shifting and smooth progressive braking, the ability to shift up 3 gears at a time and also comfortable hoods for my large hands. Much improved over the 5700 105 group set that I was using last year. No fitting instructions were supplied though but the torque settings etc were found on the Shimano dealer website so this was not an issue. 08 March 2014
Rated 5 out of 5 by perfect super happy with this purchase, really great. Feels solid and well built, light and looks fab. couldn't recommend this enough, unfortunately I couldn't fit the callipers as my bike is a steel tourer, so longer drops were needed. fitted the Shimano r650 and they work a treat! love the colour too! 29 January 2014

Answer: 
This groupset is supplied with a Short Cage rear derailleur (28t capacity) so if you wanted to run an 11-32 cassette you would need to fit a medium cage derailleur as well

Answer: 
The medium cage rather than the short cage rear mech would need to be fitted to be able to use the 11-32 cassette.

Gears or brakes?

Gears: yes. Right shifter operates rear mech. Left shifter operates front mech

Brakes: up to you! When you install, either feed the front brake to the left or the right lever, it will work fine either way. Same for rear obviously

Since CRC is not prepared to swap the 11-25T cassette in the groupset options with the desired 11-28T cassette, I have a question whether it is possible to buy a 11-28T sprocket instead (cheaper than buying another 11-28T cassette) and replace one of the sprockets in the 11-25T cassette with this 11-28T sprocket, so as to obtain the desired 11-28T cassette for the 11-speed groupset.

Do you sell a 11-speed 11-28T sprocket at all?

Answer: 
Perhaps, the problem can be resolved if CRC allow purchase of the groupset without the cassette, and allow the buyer to purchase separately a 11-28T cassette so as to enable him to obtain his desired combination of 170mm length 53-39T crank and 11-28T cassette (which option is now out of stock).

Answer: 
To run a 53/34? Yes, It is possible as they are both 110 BCD.

That would be a big jump up front though. Not sure how good it would be in practice

They don't offer 53/34 as a standard option, you'd have to buy 53/39 then pick up a 34 as a single part (which can be done for £25)

Have you considered 53/36? That's a standard option available in some places

Answer: 
Presently there is no plans to stock the 175mm groupset unfortunately. At the present price it may be worth purchasing the group and buying the cranks you want separately. Overall will be still good value and you can sell the unwanted shorter cranks.

Our groupsets are preset and cannot be altered. If you require a different item to that included, you would need to buy it separately; you could then sell the originally supplied part locally in order to recover some (or all) of your costs.

Can we have 165mm crank arm?

Hi, CRC.

First of all, thanks so much for this promotion. :) Just wonder if we can have 165mm crank arm- I know it can be hard but currently, I see 170 / 175mm only.

Wish this can be coming as X-mas gift from you.

Thanks!
