Just installed these crank arms on my bike. The fit well look good and are a few grams lighter than my old set. If you want better leverage but worry about clearance this may be the crankset for you 172.5mm (my stock set was 170) they provide a longer stroke without getting in the way or causing pedal strike increase.
Excellent value for money. Cheaper than trying to replace rings. Only thing is inner ring silver in colour whilst chain set black, but still great value for money.
