hundley Posted December 12, 2007 Report Share Posted December 12, 2007 It's all down to preference.170mm cranks mean more leverage, I'd go for these if i were you.But you might not like it.. it's all down to preference. Quote Link to comment Share on other sites More sharing options...
Ladd Posted December 12, 2007 Report Share Posted December 12, 2007 I would Say 160 , i run 160 on my echo lite and i have tried 170's on it and the 160 feel alot better ! Quote Link to comment Share on other sites More sharing options...
I_RIDE_ECHO! Posted December 12, 2007 Author Report Share Posted December 12, 2007 Im going to order them tomorow or the next day! Is the 160mm like the same size as standard onza cranks or not ???CHIGS Quote Link to comment Share on other sites More sharing options...
steve@banbury-trials Posted December 12, 2007 Report Share Posted December 12, 2007 not sure if they are definately the same size,but these echo 6061's are cracking cranks for the money,lasted longer than my tensile cranks Quote Link to comment Share on other sites More sharing options...
fyfey Posted December 12, 2007 Report Share Posted December 12, 2007 not sure if they are definately the same size,but these echo 6061's are cracking cranks for the money,lasted longer than my tensile cranks Have you still got the original cranks? Just measure from the middle of the crank bolt to the middle of the pedal axle. Quote Link to comment Share on other sites More sharing options...
Jay-Inspired Posted December 13, 2007 Report Share Posted December 13, 2007 i just brought the echo 6061 forged cranks off tartybikes and got them in 160mm for my mod and did think to myself they were a little short but im sure i'll get used to them over time its all about personal preferance if you want more leverage go for the 170s i wish i did now but the 160s should be fine Quote Link to comment Share on other sites More sharing options...
Dave@Trialtech Posted December 13, 2007 Report Share Posted December 13, 2007 Normally Onza cranks are 158mm standard I believe.Personally I've got 170mm cranks on my 20" bike. I find the little extra leverage helps me accelerate batter, which makes a great difference for the better when using short run-ups.For me I'd say that 160 are only really a major advantage when riding super super techy stuff, maybe a uci competition where you need all the clearance you can get.If I did run 160mm cranks I'd probably use an 18:13 gear ratio (a little easier than my current 18:12) to get back the quick acceleration. But that's probably because I have weedy-girly-legs! Quote Link to comment Share on other sites More sharing options...
monkeyseemonkeydo Posted December 13, 2007 Report Share Posted December 13, 2007 But that's probably because I have weedy-girly-legs!You said it !For mod, I've always used 158 cranks with 18/12 gearing. If it's good enough for the likes of Ot Pi and Cesar Canas, it's good enough for me! But as has been said, it's down to preferance and whatever you get, you'll get used to it after about 20 minutes.Dave Quote Link to comment Share on other sites More sharing options...
koxxtrials Posted December 13, 2007 Report Share Posted December 13, 2007 on my old t mag it had 170 tensiles and they felt abit long Quote Link to comment Share on other sites More sharing options...
eskimo Posted December 13, 2007 Report Share Posted December 13, 2007 I'd get 170mm in ISIS spline. If your going to buy new cranks it's worth upgrading to ISIS from Square Taper if you hadn't already done so. By the way trials-uk offer free postage, unless you wanted a signed x-mass card that is Quote Link to comment Share on other sites More sharing options...
NileBrown™ Posted December 13, 2007 Report Share Posted December 13, 2007 I used to run 175mm tensiles! well they were the only cranks I had and didn't want to buy new ones... but then I snapped them so bought shorter 170mm echo forged Quote Link to comment Share on other sites More sharing options...

I_RIDE_ECHO! Posted December 15, 2007 Author Report Share Posted December 15, 2007 Well in the end i decided to go for 160mm! If you buy the echo forged cranks would it be different gearing if you left the freewheel on the hub and put the fixed cog on the front??? It would still be 12/18 but just the other way round right....? Because i can't really be bothered to take my freewheel off because it is a bit of a c**t to get off!!CHIGS Quote Link to comment Share on other sites More sharing options...

Think about it... If you put a 12T on the cranks and ran an 18T freewheel on the back (which I think is what you're getting at), the gearing would be so easy you would actually go nowhere. The only way of doing it is to get the freewheel off your cranks and onto the Echo's. Or, if it's just a cheap ACS or something just buy a new freewheel at the same time.Dave Quote Link to comment Share on other sites More sharing options...

I thought that it would be the same but just the opposite way around, but obviously not!? I have just got a standard freewheel on the hub which i ment would be hard to get off! But i am ordering a tensile now enyway so i will have to take it off! Cheers anyway mateCHIGS Quote Link to comment Share on other sites More sharing options...

Basically to run an 18T freewheel on the rear hub, you'd need to be running a 27T on the cranks to get the same gearing as a standard 18/12 setup.Dave Quote Link to comment Share on other sites More sharing options...
Charlie Jennings Posted December 16, 2007 Report Share Posted December 16, 2007 The tapers f***ed up on my Echo Forged (ISIS). Spend more and get some better cranks. I've got Try-All ISIS now Longer cranks, More leaverage. But they are heavier. So if your a weight freak (like me) get shorter ones (although i got 170mm) Wow, your really NEVER going to get validated...Yeah he will. I did! I got validated in 5 days!

monkeyseemonkeydo Posted December 16, 2007 Report Share Posted December 16, 2007 The tapers f***ed up on my Echo Forged (ISIS).To be honest, you must've done something wrong to screw up ISIS splines... They may distort a little over time but should be almost impossible to truly destroy. I'm running the Echo Forged's on my Inspired and really like them. TryAll's will be no different in spline quality and I expect the material is virtually identical.Anyway, hope you don't snap the Tensiles, Chigs...

Well Andrew Chai and Steve Rodgers have both have problems with them. If you dont know. Andy is sponsored by Echo, and Steve is sponsored by HeatsinkSo. it looks like a common fault.Polyfiller fixed it on for a bit. go for 160 because there for 20" and 170 are for 26"HAHA! That is the most ridiculous thing i've ever heard! Whats 175mm for then? Quote Link to comment Share on other sites More sharing options...
