Hi guys
My brother wants to get into racing but I need to restrict his gears. But I don't know how to restrict the front derailleur from using the big ring. Does anyone no how to?
Thanks

    One of the limit screws on it will be marked H. Screw it in until you can't shift to the big ring any more.

    Why do you need to restrict his gears? Remember it can a pain to put right afterwards...

    Otherwise, as above.

    Are you sure you can't meet the gear restriction by using the limit screws on the rear mech - effectively just blocking off a few of the smallest sprockets on the cassette ?
    it's a hard life if you don't weaken.

    Yes, that's the way I understood gearing was normally restricted - adjust the rear mech limit screw so you can't access the smallest cogs (the shifter will still click to them but the mech can't move that far to the right).

    If it's to be permanent (i.e. race-only bike), you can buy cassettes which start at 14 or 15 teeth, which give you all 10 or 9 or whatever ratios, with smaller gaps between them.
