I have Super Record compact group but need to run a set of 53/39 cranks for a 300km flat event and the speeds require a standard crank if Im not to spin like a muppet

Id rather not run to another SR crank when chorus or record would do just as well...but does anyone know if the SR bottom bracket is any different (apart from the bearings) such that Id have to swap them out as well?

thanks

    I think its to do with the SR cups not having seals as Record use standard bearings and SR use ceramic which don't need sealing.
    Just swpa to standard bearings or the SR cups and your fine.
    I stand to be corrected though

    The seals are on the bearings - the cups are just receptables to locate the bearings and AFAIK the only difference is the black anodising - the bearings themselves are a standard-size. Its worth trying - it'll be pretty obvious if they don't fit
    Make mine an Italian, with Campagnolo on the side..

    According to someone on another forum all you need to d ois put the seals into the SR cups. I'll be trying this myself shortly as the black cups will look much better than the silver. I'm then sending the silver off to see whether they can be anodised, which is a whole different topic.

    Why not buy a 52 tooth and a 36 Tooth 110BCD chainring ( 52 to 34 would probably be a massive drop ; maybe the 11 cogs would make up the difference dont know I run Shimano ) and fit them to your SR spider ?

    No difference at all weeve, I ran a Fulcrum R c/set on Campag cups, changed to a Fulcrum RRS and then (later) changed the cups to Super Record (the black ones) - all worked fine with no issues at all so the bearings etc are all the same measurements!

    Hibbs, getting a set of silver cups anodised would be prohibitively expensive - why not get a set already done - they are only around £18?

    like the last reply... will just get some record ones then...I like the spider idea but the drop between 52 and 34 too much and would trash derailleur unless chain excatly right I assume...

    Where from? A few of us have been looking for somewhere to get coloured Campag UT cups for a while but can't find anywhere. A tip-off would be extremely welcome!

    I got mine off ebay about 3 months ago.

    You could also try these http://www.wiggle.co.uk/p/cycle/7/Campa ... 360049529/

    or these http://www.parker-international.co.uk/1 ... -Cups.html

    or even these http://www.ribblecycles.co.uk/sp/road-t ... AMPBTBR480

    All cheaper than what I paid :) (or am I missing something here? :? )

    Hmm. Ok. I meant anodised into a colour, not just the darker SR cups, which is what I'm putting on in the meantime. Thanks anyway,

    Ah! You may find somewhere able to do that but the main problem will be in keeping the inside of the cups clear and it would still work out (a) expensive and (b) may take a while as the anodiser would want to wait until he has several orders for bits all to be done the same colour)

    I looked inot getting parts anodised a while back (engine stuff) and it does get very complicated/expensive for one-off items!

    sorry...just to be clear..

    I meant cups with bearings etc - full SR BB set used with record or chorus.. not swapping out the bearings etc ... Its not a big deal to buy new BB as well but obviously easier if dont have to bother...
