Title: Crank Lenth.......How longs yours !!!!!
Post by: Peter J on January 08, 2008, 09:16 PM
I'm picking up my first BMX after a 21 year break...I'm getting a cruiser (from SE-Bmxer :-) ) and wondered what crank lenth people run on these. I was thinking of running 170's as I'm only a bit taller than Spen 5ft 7in 29" leg..... :-[

170mm is too short, Pete.

Try 175mm or 180mm.

I've got 180mm on my BMX bikes and 175mm on my mountain bikes.

I was using 180mm twin pinch Redlines, then tried my 175mm Pro Class Cranks and loved them. So swapped my 180mm twins for 175mm twins with Tony796.

I thought the 170mm were more for freestyle bikes rather than race bikes. But I had them on my Redline and they were fine, didn't even really notice the difference.

I've got 180mm on my BMX bikes and 175mm on my mountain bikes.

I'm more or less with you there Mike.

I used the 180's for years on BMX's, now i use 177s on both 20" and cruiser. (175 on my mtb). I'm 6 foot, but I've got a long body and only 32" legs.

If I had legs as long as Flem's I'd be on 185's too.

I'm 5' 10" with 32" legs and have used 185mm since I was 14, never looked back I love them and have them on just about every bike I have but if I was advising anybody then 180mm is a great general purpose length.

185mm means you don't have to spin as fast as you did as a youngster also... harder gearing, more leverage... gets this old timer over Dag's doub's 8)

Don't think I'll get them, need to improve the bike skills first + Like I said don't think the place for clip’s is on the track just wondered what other people ran...............although  considering the leather chaps you recommended for this season            :D

Just need to find a leather cap I can fit on top of my helmet  :uglystupid2:

I'm running 180's on my Torker and Brew cruisers, with 185's on my 20" Free Agent. (Not tried the long 'ens yet, but recon I'll run a slightly harder gearing with them.)

That's assuming I ever get to ride - fingers crossed cos I haven't ridden a bike since MK in the summer.
