    Havin read my question and
    Havin read my question and your replies, thanks for them.
    I realize that I haven’t worded my question very well!!
    I am looking to buy a new ‘best bike’ and keep the cube as a winter bike.
    The bikes I am looking at (Ribble, cube, sensa ) all seem to be about £300
    Difference between 105 and ultegra spec, is the extra cost worth it ??

    new 105 carries down most of
    new 105 carries down most of the important innovations of the latest ultegra groupset, and functionally it’s very difficult to tell the difference between the two. it’s heavier, of course, and if that’s a deal breaker then go for ultegra. but like others have said, saving the weight in the wheels will affect the feel of the bike a lot more

    Right then, i own a Cube
    Right then, i own a Cube Attempt and have done for the last 2 1/2 years. It is now my winter bike so will remain 105 equipped as it is cheaper to replace. The groupset on there has done over 10,000 miles and is still doing the business with no issues.

    There is nothing wrong with the 105 shifting, just make sure that you are cleaning and maintaining regularly. One thing that you may want to change is the front mech. 105 is quite noisy and having changed to an Ultegra FD on another bike (now retired) there is a definate improvement.

    So the saving of £300 on the groupset should allow you to get a wheel upgrade. Fulcrum 5’s or Campag Zonda’s are great and can be had for £215-£250. Grab yourself a cassette too and you have yourself a pair of winter wheel and dry weather wheels 🙂

    Both my bikes run 105 (5800)
    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.

    I swapped from Tiagra 4600
    I swapped from Tiagra 4600 (10-speed) to Ultegra 6800 early in the year and the difference is very noticeable – in particular the front shifting and brakes. However I got the groupset for an absolute song and if i’d had to pay retail for it, i’m not sure i’d have done so.

    If 105 5800 had been around at the time and I had to pay retail (especially at the 300-odd quid that Merlin keep getting them in for) i’d have gone for 105 over Ultegra every single time (Just my feeling obviously). Most of the major mechanical changes seem to have trickled down from 6800 to 5800 so I wouldn have thought you’d be getting a fair chunk of the benefits. Personally i’d go with the others and say spend the cash on wheels if you have it spare – perhaps a nice pair of hand-builts.

    Hi, just in my humble opinion.
    Have ridden both kits very recently, both the same age (roughly) and same gearing and I and the owners of the bikes could not tell the difference when riding – zilch. There may be differences in a few ounces but I agree with the above post that your £300 would be better in wheel choice.
    Kit ‘gurus’ may get a little more moist on the Ultegra over 105 but for general cyclists the differences are not night and day.
    Regards,

    Trikeman. 😉

    A friend reckons the brakes
    A friend reckons the brakes are the biggest thing he notices jumping from 105 to Ultegra, unless of course these have trickled down to the latest 105

    Putting the extra £300
    Putting the extra £300 towards wheels would probably be better.
