Converting drops to aero bar - which brake levers

I'm swapping my drops for a base bar and clip on setup.

I think I'm going to go for the profile t2 aero base bar and need to get some brake levers. I want to get cost effective internal routing brake levers - any suggestions?

Also if anyone knows the internal diameter of the t2 aero wing base bar?

    AFAIK most 'bull horn' bars have the same internal diameter - usually 22mm. I've got both DiaCompe and Cane Creeks carbon - I'd choose the later because of the better build quality, they have a return spring so don't rattle and they don't have the cheapness of the DiaCompe expander bung.

    Thanks Monty.
    Do the Cane Creeks (200TT?) route the cable internally?

    You can still use STIs on your bullhorns. Thats what I've got on my lo pro.

    No, the cables run on the outside to get the leverage - some bars like the Profiles have slots / grooves for the cables but TBH the extra kink in the cable creates more drag. Whilst in theory you can use STIs/Ergos the cable run is never neat and you often has to leave a loop of outer to get a smooth 90 degree bend.

  • HI there.

    Bar end levers are the way to go - if you're setting up the bike for time trialling then you want to maximise the time you spend streamlined on the aero bars. Moving your hands to change gears on the STIs is only going to slow you down.

    The STI's are going over to my winter hack bike build, the 'good' bike is going to be tri / fast training so full aero.

    It's bloody annoying trying to figure out which one's are compatible though - Profiles own QS2 levers cover an inside diameter from 18.5 to 21mm, others have a narrower range like theTektro RX5 which covers 19 to 20.6mm which may or may not fit my bars..?

    Check the bar internal dimension but they're normally standard (22mm IIRC.)

    Rob,
    I had a look at those but I think they have external cable routing?
    I've opted for some Tektro Carbon RX5's off ebay - just hope they'll fit.
