@DCLane - does front much not give more for muck getting clogged round?
Youth Cycle Sport review recommends Singles. For road racing with restricted gearing do you need a double, or will single suffice.
@Beebo she has used 21 spd MTB but think she's been in wrong gears at times. Puts it into granny ring at front and forgets to change back after climb!
I've another thread asking for opinions on some options. Your thoughts would be appreciated - thanks!
