Polo Bikes

why is picking cranks such a massive ball ache?? I just want something that fits my bike (135mm rear spacing, 68mm bb shell), isn't too heavy and preferably isn't too expensive.

What length?? Bb type??

Onza do a square taper 165mm with 24 ring and bash guard for about 40 quid.

Failing that look mtb raceface do cranks in every length and can usually get cheap 2nd hand ones on somewhere like single track world forum for not a lot of money.
