SS crank issue?
I just wanted to get some insight on this matter, because its damn wierd to me. This year, I've gone through 3 sets of cranks. First one was bent from a wreck, w/e, but the next 2 sets had the same issue, and idk what causes it. The other 2 sets of cranks have had the threading strip right out of where the pedals screw in. And both times, I've used Anti-sieze compound, and the threads just tear right out.
Now bear in mind I do ride this bike all the time, rain, snow ect. and someone was telling me that the compression is the culprit, but it seems wierd that 2 sets, albeit used, but otherwise healthy cranks have stripped out on me.
Is this related to the extra strain put on a driveline of an SS, am I riding it wrong? I know they weren't cross threaded or anything when I installed them.
Just curious to see if anyone has any ideas as to what causes this or if you've had a similar problem.

Maybe it's the pedals.

you're definitely putting more stress on the crank with an SS since there isnt any gear reduction. But that is odd, seems like it shouldnt damage the threads much if they're tight. There seems to be enough engagement with most pedals.esundell90 said:I just wanted to get some insight on this matter, because its damn wierd to me. This year, I've gone through 3 sets of cranks.

I'm currently building a SS with a older bike and I will be using the older cranks that came on it. Specialized Strongarm cranks to be exact. Are the SS specific cranks I see for sell made stronger then conventional 3 ring cranksets???
thanks
thanks
mostly not. There might be some, but most are only different in the chainring/spider department. Your crank should be ok for a while at least. I cant see it being worse than most other non-external bearing cranks as long as you torque them properly.hairyharris said:I'm currently building a SS with a older bike and I will be using the older cranks that came on it.

I'm in Marquette.
I was wondering if the pedals were the issue too. I just threw them out since the bearings in the pedals took a crap, and I got new pedals.
As a thought, could the frequency with which I change my pedals have something to do with the threads failing early? I do change between my eggbeaters and reg. pedals once or twice a week during the summer?
I'm thinking about just buying some nice new cranks to see if that solves the issue. Anyone have suggestions for a good set to run on an SS for a reasonable price?
I would look for some used or takeoff xt cranks.
Can't go wrong IMO.
Your problem makes me think user error. Consistently the same problem and when you mention you swap them out all the time....Mmmmmmm
I am not saying it's user error but if i had to guess.....

I believe this could have plenty to do with it. Frequent removal & replacement means lots of opportunities to not get them quite tight &/or marginally wallow the threads.esundell90 said:...

It's the threading/unthreading that's killing your cranks. Buying another set of pedals will keep you from spending money over and over on buying cranks. Cheaper in the long run.
id go with the SLX duel ring cranks with steel pedal inserts
chain reaction also had some saint cranks for a good price
Marquette is sweet
I'll take a togo's large chicken bacon ranch sub please

yep, aluminum threads arent so hot for threading/unthreading on a regular basis. I'd try putting some helicoils in there. I bet they'll last alot longer, plus you'll be able to save the cranks.
Yeah, good call on the heavier duty steel threads and such on the cranks, that prob. will solve my issue. I'll have to look for a set here after the holidays.
