SS gearing for borrower

I've finally decided to up my ss gearing. 42 x 16 just isn't long enough.

Any recommendations? I obviously don't mind spinning fast at the top end. I like to use my ride into work as a proper workout, but I don't want to have a gear I will hate as soon as it gets windy and cold.


Any suggestions? My knowledge on stuff like this is very limited.

    42-16 is 70in so a 15t would knock it to 42-15 and 74in which would be cheaper.

    or if you got a 46t chain ring you could have.
    16t = 76in
    17t =71in

    44t chain ring would give you
    16t = 73in
    17t = 68in

    I personally run 46-16 I weigh a lot more than you and manage to grind though head winds and up most surrey hills, managed 121miles few months back...I can nudge 30mph on a good day though i'm unlikely to hold it at more than 24/25mph 120rpm

    Think I'm probably looking at 48x15t on the plans for what I'm going to order next week. Man up Rick?
    What do you mean you think 64cm is a big frame?

    Not sure you can go lower than a 16t freewheel. Bigger chain ring is probably your only option. 46T should be about right, any bigger jump may cause injury problems.

    I've just ordered a 17t freewheel to give me 48/17.

    I quite like spinning the 15miles each way at 110rpm but much above 25mph and it gets a bit bouncy. I think I need to lose a tooth at the back if I want to break the 20mph average commute.

    Surely you have to make allowances for the extremely short cranks and tiny wheels? Even more so than SS gearing for a hobbit.
