Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

165mm vs. 160mm crank arms difference

I'm kind of newbie here so here it goes I bought a fixie bike a few weeks ago and would like to change the stock white crankset (165mm crankarms) to black however the seller does not have black one with 165mm crankarms, he does have black but 160mm crank arms my question is am I gonna feel much of a difference 165mm vs 160mm? or should I go for another crankset brand like Origin 8 with 165mm arms?

From what I've gathered in my short time here, you may notice a slight difference at first but for the most part it should feel about the same.

The problem w riding 160mm cranks is that you might fall in love and forever want short cranks, which are not always easy to find.

Go for it.

You will have about 3% less leverage. My bet is that you won't notice the difference, unless you have a toe strike or pedals strike issue, and that will be better with the shorter cranks.

Especially since you're new, and I'm sure you have no idea what spinning cranks of different lengths feels like, you won't notice a difference.

Well, yeah, but get narrower pedals first, save your money. Especially if the cranks aren't a marked improvement.

Also- check how much clearance you have between the crankarm and the chainstay- BB's are cheap.

How does bumping a dead thread from March help? Hmm?

Also, it helps because pedals are cheaper than cranks.

The biggest reason for getting shorter cranks is to improve ground clearance in corners. Narrower pedals do the same thing.

I just spent a ton of money going from 170 to 165 to reduce amount of knee angle at top of stroke. I have realy short legs or I wouldn't have spent the money. Don't know if it will make a difference or not. I "suspect but don't know" whether the shorter your legs the more benefit or less noticeable the shorter cranks. Recumbent riders often ride really short cranks like 150mm-160mm.
