  • 5800 11 speed…

    I’ve been toying with upgrading my 3500 Sora stuff to 5700 105 for a bit, so just went to take a look at the Ribble sale.

    Their groupset sale will do me 5800 11speed for £279, including brakes I’m not going to use.

    I only really wanted 10 Speed, so started building a basket with 5700 sti’s, cassette, rear mech and cx50 crank. I’ve already hit £230. Cx50 fd and a chain is going to take me within a fiver or so of 5800.

    Am I being silly passing up 11 speed? I don’t really want compact double ratios, I’ve got Dural 36/46 rings on my existing crank. I’m guessing the brakes won’t have much sale value, what about brand new 5800 rings?

    … Or just go luddite, buy the 5700 sti’s, cassette and Rd and keep everything else I already have? I could use a new BB, but a crankset is an expensive way to do that…

    Another point/option, I know the drive chain is narrower, but would my existing 9/10 Speed rings be usable in an 11speed drive train? Guessing it would be non-ideal…

    Even more fundamental objection ahoy.

    I’ve got a 135mm back end with a mountain bike hub including rotor mount. 11 speed cassettes need a wider freehub I believe, which in turn is going to make for needing a shorter hub body I’m guessing to cram it all in.

    Does this effectively write off 11 speed in its current form for me, without sourcing a new hub and rebuilding? Is there even a hub that will take an 11speed Road cassette, a disc rotor and 135mm?

    There are, but not many, and for that reason youre probably better sticking with 5700.

    Pretty much answered this I think.

    11 speed bargain means probably spending the same again on new wheels or rebuilding rear with something like a CX75 hub at the least.

    Guess I’ll weigh up how much I actually want a new transmission as my 9 speed is perfectly functional if tatty, then probably go 5700 if anything.

    I did find an amusing Zinn article talking about taking a grinder to a 9/10 hub to get a 10/11 freehub on and then redishing, though! 😯

    Yep, some freehub bodies can be filed down. What hub is it? Some can be converted, but it is extra faff certainly

    Edit: if you like your chainrings why change them? Mech/STIs/chain/cassette is £250 or so on Rose Bikes. Current rings will be fine
