180mm or 175mm Crank Arms? Whats the point?

[martylaa]

Never raced for a team when i was a kid so not sure about this, but whats the point of making cranks 5 mm longer or shorter, would anyone notice, we're talking about 5mm extra or less length here, surely no-one would know the difference would they?

[Jon The Bassist]

You definitely do notice! More leverage with longer cranks and they suit bigger riders.  They also have the effect of making a gearing feel easier but you have to move your legs in a bigger circle.  Likewise shorter cranks for littler dudes, less leverage but can be easier to spin as your legs have to go in a smaller circle.

So...Jon do you consider yourself a bigger ridder or a smaller one? Just for referance?

[Jon The Bassist]

...erm, probably bigger in my case 

[bmxboy70]

It depends on the original size

i'm say 6ft 1"
could i ride 175mm's on a cruiser or should i go 180mm's, not racing just for riding in general and having a piss about

[brummie]

But it's only 5mm, if my knob grew by 5mm, the missus would still be unimpressed

175 ON A CRUISER IS SPOT ON FOR RACE OR RIDIN MATE

I think at my age and level it makes no difference I’ve used 180’s and thought they were too long (I’m 5’ 9”) I’d be much happier with 175’s or even 170’s....I've got short powerful legs  so a shorter crank feels better for me.


TBH put a pair of trainers on with a thick sole or some deep caged pedals and that’ll add 5mm to your crankage.

I had 170's on my 82 supergoose rider and fookin hated them 

Got 180 redline twin pinch jobbies on her now and I love em - great cranks for a rider IMHO
