    I recently upgraded my Boardman Pro Carbon from 105 to Ultegra. It totally transformed the ride quality, as far as shifting was concerned. Although a lot of the difference was due to the move from 11-25 to 11-28, the Ultegra just feels a whole lot better than the 105 set overall.

    But is that 2015 v 2015. When 6800 was launched it was over £900. The latest (2015) Chorus is cheaper. In fact I’ve not seen anything relating to a Ultegra upgrade for 2015.

    It isn’t.

    SRP for 2015 chorus is £997. 2015 Ultegra is £775. I have never ever seen Chorus retail cheaper than Ultegra. Even with retailer discounts. The above can be found for £840 and £550 respectively. That disparity of £200-£300 has always been there. Even if Chorus SRP has come down this year.

    My Bianchi Sempre Pro has a full Ultegra 6800 groupset (nicely upgraded at purchase) and the brakes are stunning, by far the stand-out improvement over my experiences with 105 5700 on a friend’s bike and my earlier 105. The braking is powerful and controlled, so it does give you the confidence to push a little harder. I’ve also just bought a CAADX with 3500 Sora fitted and the gear-change on that is suprisingly slick, so I’d be amazed if Shimano haven’t managed to get the 105 gear-change within a knat’s breath of the Ultegra smoothness.
    Pretty what everyone else says… the Ultegra brakes are superb.

    105 5800 is 11-speed. The pretty universal consensus is that it shifts/brakes the same as Ultegra 6800, and the only difference is weight.

    I think the general consensus is that it shifts the same as Ultegra, but the brakes are maybe not as good.

    There has also been a bit of Ultegra bashing, or mis-positioning on this thread, make no mistake, the 6800 groupset is an incredible piece of kit, one of the best groupsets ever produced pound for pound.

    difference you’ll notice between 105 and ultegra is the brakes.

    Test rode the new bike yesterday and loved it, the Chorus groupset looks stunning and works really well, the brakes are pretty good as well and is far cheaper than Ultegra to buy as a stand alone groupset. Deposit paid and the bike is ready for when I go pick it up 🙂

    As for SLX being better than XT, I think Shimano need to go back to drawing board or drop the price of XT, may be they could do the same with Ultegra.

    I have Ultegra, apart from the brakes I am not overly impressed, I have had plenty of shifting issues on the back and it’s not a very positive shift change when tapping the levers. I am looking at a new bike (Bianchi Infinito CV) I will be giving campag a go. Wanted Super Record but looks like it will be Chorus.
    It’s funny because I found XT on the mtb rubbish in muddy conditions but SLX has been faultless. Apart from the XT shifters and ice tech brakes I run SLX.

    I’ve used both 5800 and 6800
    I’ve used both 5800 and 6800 and I’d say that beyond weight, the only perceivable difference I have noticed is with the brakes.

    6800 brakes are unfathomably good… best I’ve ever used. 5800 are no where near as impressive.

    I’m going to have a go at re-cabling them, to see if its just a bad set of cables or something, and also try changing the pads to Ultegra/Dura Ace.

    The 105 brakes lack bite and modulation (comparatively) and it feels as though the success of the design relies on stiff, efficient cables and soft brake pads. The lever rate is such that without these two parameters, there is no bite unless you squeeze real hard.

    I’ve also ruined a 5800 rear mech, simply by riding it with a slightly misaligned mech hanger. By slightly misaligned I mean slightly, and effectively the lower jockey wheel has worn and is now throwing the chain at the more extreme ends of the block. So I’d suggest its a little more sensitive too.

    Can add a little bit here. I switched from sram force/rival to ultegra 6800/105 5800 this last summer on all my bikes, I have 105 gears/shifters on my cx/gravel bike, and full ultegra on the 2 road bikes, the mrs also has full ultegra on her road bike.

    big differences are weight, as the shifting action feels the same, and the other difference is the 105 lever gets a little colder due to being non carbon. a couple of my team mates have gone from ultegra/dura-ace to 105 and they all say that the brakes are about the same, once they changed pads.

    crankset i cant comment, as the cx bike has FSA slk’s, and the roadbikes are all ultegra. the chainrings/crankset are stiffer than the previous sram cranksets I had, and don’t suffer from the chronic chainsuck that sram can do. I only have 6800 cassettes and chains, mix of 11-28 and 11-25.

    my final thoughts, 105 drivetrain is great, but upgrade the chainset( for the weight issues), and brake pads plus a pair of bling wheels

    Both my bikes run 105 (5800) and the difference in the performance between the two was huge. The newer of the two group sets shifted like a dog whist the older set was light as a feather. If you were blind tested you’d think they were different groupsets.

    The only difference between the two was that i was using 2 year old jagwire cable outers on the new groupset whilst the older set was set up with brand new cable outers.

    THIS.

    Swap out your cables every 1-2000km. It’s £10 worth of hardwear* and 20 minutes, max. for a vastly improved experience.

    * a lot less if you buy in bulk.

    Are you just referring to swapping the inners though? Swapping the outers necessitates new bar tape and the time to fit, surely?

    Zombie thread resurrection 🙂

    Have unwrapped and re-wrapped my bartape quite a few times (Brooks leather) – not a problem. If you were going down past the hoods and re-doing the drops/bung, yes that would be nasty.
