hiya bike forum people i need help
i have a lovely 1968 green viking bike which i decided to turn single speed after the gears mucked up to much, didn't fancy a fixy.

Anyway i had quite a cheap stronglight crankset on there as i wasn't sure i would keep the bike, the pedals churned up the threads on the crank arms ( i know pretty unusual) and now i need a new one.

so my question is i have a budget of £60 and i want to get the best crankset i can buy for that amount of money?

i've looked around but cannot make a decision of what brand or even what type of metal to go for i've heard heard 7075 aluminium is good but i need some serious advice
i need it to be 47t or 48t
thanks

A good shop can fix those threads with an insert called a "helicoil." Then you have to promise not to mess them up by cross-threading the pedals again ;-)

If you're buying a SS crankset for that price range, I wouldn't worry about alloys, or brands for that matter. They're all about the same for those purposes.
