Hi all
First post so hopefully i don’t do anything wrong- apologies if i do

Problem
I’m 6,4″ (height)
I have a fixie which currently has :
44T Chainring (CR)
175mm Crank arm (CA)
18T Free/ Fixed cog (currently riding free due to laziness )

The chain, chainring and freewheel cog are gone and need replacing. The current chainset/crankset is orange so i was thinking of replacing the whole thing with something simple (black/silver) and increasing the chainring to 48T.

Only problem is in the UK, finding anything longer than 170mm is difficult. I’ve managed to find this which is 175mm CA on ebay but the chainline is 45mm and shipping it to the UK is kind of…….

I was wondering if i get This which is 170mm CA (or any other 170mm CA) and i just raise my seat post a few mm, will it workout the same?

(I’m aware that Crank arm length is related to your inside leg measurement and technically i should go for a long CA but with it being so difficult i was hoping for other solutions

Any help/ advice / recommendations to 175mm cranks would be greatly appreciated thanks.

thanks cynic.

i’ll take your advice and get 170mm

I’d be inclined to agree – personal view is that cranks are typically longer than they should be. Some (slight) advantage in a shorter crank is that there’s less risk of pedal strike when you move to the fixed cog. Some argue shorter cranks are easier to spin, which would suit a more fluid style of pedalling on fixed.

Where are you riding it? kilo on the track or commuting, or something in between?

Might not have the look, but will do the job.

Interesting read, video was a little annoying. The way he spoke seemed like a typical american TV commercial but still interesting information.

@honourablegeorge :

Thanks for the link, i did a little search online and came up with this – http://www.bikeforums.net/singlespeed-fixed-gear/608127-sram-s100-1-1-single-ring-crankset-anybody-know-anything-about.html not good things by the looks of it but it could be internet speak.

@twicewithchips
I usually ride for commuting between clients and gym. A minimum of 9 miles a day.. if that makes any difference

I’d say go fixed and 165 Miche Track. The reason you will want shorter cranks is due to pedal clearance when cornering. As others have already said, crank length is not so important, particularly riding fixed, spinning is the more valuable skill and slightly shorter cranks will help you spin faster.

As for gearing; 42:16 or 48:18 assuming you don’t ride big hills. 44:18 is a little low for road.

iwed – I have the S300, which has served me well, is also cheap on EBay – uses a GXP BB rather than the Powerspline used by the S100.

what would you guys recommend ?
