|   TruVativ Team Stylo cranks + Eggbeaters - question | *rt*
Aug 4, 2003 7:10 AM | | is anyone else using this pedal-crank combo? if so, have you had any trouble with the pedals stripping out of the cranks....particularly the non-driveside crank?
thanks.
rt |
| actually rt, I had the opposite problem.... | namaSSte
Aug 4, 2003 7:28 AM | | go figure. I also ran into the same issue using ATAC pedals on my old Stylos. Since getting the RF Turbines, all has been well. Maybe I over torqued them on the TV's but I definitely never had pedals loosen and/or strip. Sorry Im not much more help. One thing I might suggesst is to have a shop tap them if they aren't badly stripped. To make up for the small amount of lost material, use some teflon tape on the pedal threads and torque to spec. |
| unfortunately, they're badly stripped... | *rt*
Aug 4, 2003 7:43 AM | | since this is the third time it's happened & the 2nd crank arm i've trashed i think i'm going to attempt to cut my losses and get a whole new crankset. either RF or XTR.....i find throwing money at the problem usually....uh....makes me poorer. ;-)

| I think you're spot on rt....besides, new parts are fun! | namaSSte
Aug 4, 2003 8:31 AM | | and no, I don't know a transgendered person who told me :) Seriously, look at the Turbine LP's. I have loved my RaceFace cranks and they are trouble free and really stiff. The TruVativ's are nice, but they really don't compare to the RF imo. Good luck and keep smilin despite the drivetrain woes.
Peace. |
| i'll check out the RF.... | *rt*
Aug 4, 2003 8:46 AM | | it may come down to what i can get the best price on.
thanks!

| same combo | ignazjr
Aug 4, 2003 7:59 AM | | I'm running the same combo, and have been since last October. I've experienced no problems. The pedals have been in and out of the cranks a few times for service. I've had the cranks since March 2001. |
| hmmm. maybe its me. | *rt*
Aug 4, 2003 8:08 AM | | i should fire my mechanic....oh wait, i AM my mechanic. ;-)
thanks!
rt |
| same combo on two bikes.......... | Fat Tire
Aug 4, 2003 9:31 AM | | .......and I've had no problems for about 800 miles between the two. I've been told by a few mechanics that many people put too much torque on their pedals during installation, don't know if that's your problem but it may be.
Good luck! |
| Don't forget the washers.. | Diamond Dave
Aug 4, 2003 9:39 AM | | TruVativ provides washers with their cranksets intended to go on the pedal axle/threads. The washers act like a stop to keep the pedal from stripping the crank as you described. Do you have the washer thingies?
DD |
| Exactly what I was thinking. | NuMexJoe
Aug 4, 2003 10:10 AM | | The literature that came w/ my Stylo Teams gave the impression that the washers were optional, but I've made sure to use them. But, I'm not using Eggs, so it could be something else entirely.
- Joe |
| yup. used the washers. (nm) | *rt*
Aug 4, 2003 11:08 AM | | |
| not quite correct | ignazjr
Aug 4, 2003 11:46 AM | | The washers aren't there to act as a stop. The pedals will stop threading when they hit something, be it the crank arm or a washer. The washer is there to prevent fretting. Fretting is microscopic wearing away of the metal surface due to metal on metal friction, which eventually leads to a fatigue failure. Many folks believe fretting is what helped to contribute to old Nuovo and Super Record cranks cracking at the pedal eyelet.
The reason that the manual mentions that they are optional is because a pedal/washer/crank interface will still cause some fretting, thus, in some folks opinions, making the need for a washer redundant.
My guess on the stripped threads is that they got crossthreaded at one time or another. Even slightly will do the trick over time. Aluminum is much softer than steel. I bet Truvative has left arms available. If it was up to me, I'd contact a shop I'm in good with to see if they could obtain one. |
| this was a brand new crankarm... | *rt*
Aug 4, 2003 12:41 PM | | it came directly from TruVativ after the last pedal incident i had. TruVativ was awesome about sending it out to me no questions asked, but at this point having gone through 2 left crankarms in about a month i'm hesitant to try to warranty another one. at this point i'm pretty sure that my best bet is to cut my losses and get something else.
besides, as i mentioned in a post below, i can get a lighter bb/crankset and drop some weight off the bike.
rt |
| weird | ignazjr
Aug 4, 2003 1:32 PM | | Not accusing of bad mechanicking, of course. I wonder if they got a batch that were forged incorrectly. I'd call them up and ask if they've seen other problems. Odds are high that they have (if they admit it). That's probably why they swapped them out no questions asked.
Liked the race report. Always good to race in a class that is challenging for you. Good luck next go around. |
| indeed | *rt*
Aug 5, 2003 5:10 AM | | no worries. i'm beginning to question whether it really is something i'm doing. i'm a careful wrench but to go through 2 crankarms in 1 month makes me wonder.....
to be honest, though, i haven't been all that thrilled with the crankset as a whole. i've had problems with the driveside as well: currently i think it has bonded with the bb spindle because the washer TruVativ provided was slightly too small and as a result of the pressure from the crankbolt it has bent so that it is concave and wedged into the base of the crankbolt threads. as a result i can't remove the driveside crankarm. i think i will be drilling it out in the near future.....another good reason why i should look into a whole new crankset...... ;-)
thanks!

| Well *rt*... | ®andyA
Aug 4, 2003 9:44 AM | | ... if you're going to throw money at the problem you might as well not spend so much of it eh? Might you consider XT over RF/XTR? Over in the Drivetrain board there's always been the view that the XT (or better yet, LX - but considering you race, XT is the better choice) provides a very good price/performance ratio. Might be a solid option for you.
næstep recently posted a clipping from a German bike mag showing test results for various cranks.

Sorry to hear of your DNF in Masters and the return of the drivetrain (sans Jedi :p) problem.
I do have a set of Turbine LP's and Stylo Team's. But both are sq taper.
Also being the 'weekend warrior'-type, I don't hammer as hard as a racer would so any comparison I could give would be biased to those conditions. But with that said, the RF is a nice 'set - very solid and light compared to the Stylo. Just match it with a good BB and you'd be set.
Randy --> don't read German, but I read numbers pretty darn swell :p |
| XT=creaks | Jisch
Aug 4, 2003 10:44 AM | | I'm in the middle of a battle with my 2003 XT cranks/bb trying to eliminate a creak. I wouldn't buy XTs based on my experience. Of course I may have just got a bad one. According to Shimano - creaking is not indicative of product failure or some such rubbish.
John |
| Have you looked... ? | ®andyA
Aug 4, 2003 10:53 AM | | ... at the spider interface. There was a post not far back (I'm trying to look for it) where a poster said that their creaking was eliminated by lubing the spider/rings interface.
May be an option.
Randy |
| I think I found... | ®andyA
Aug 4, 2003 11:05 AM | | ... your reply over in General (oh, and it was threadlocking, not lubing the spider). Did you try the threadlocking tip? Did it work (or not)?
I think this was the link I was recalling:

Randy |
| Wow! | Jisch
Aug 4, 2003 11:45 AM | | Thanks for that search. I have been looking for that... I found some other "kinda" answers, this is the first one I've seen that seems to address my problem exactly. Going to try that tonight. Lubing the other parts (Splines, cranks, pedal bolts) has done nothing
I've had these dang things apart so many times its not funny. Hopefully this is the fix. I am pretty convinced the problem is this spider/crank interface. Otherwise some of the things I've done up until now would have made a difference.
Thanks again,

| 2003 XT =Stiff and quiet | glenzx
Aug 4, 2003 12:34 PM | | After POUNDING my 2003 XT cranks for part of this season, they are quiet strong observers of other bike parts (and a fram) coming apart. I'm 6'-0" 195 pounds and have put about 1000 miles on mine with absolutely no problems (yet?) since June. I am very fastidious about maintanence on my bike so I always check/tighten the retaining bolts as needed and of course greased the BB spindle and shells at installation. What is actually creaking? Just curious. |
| Answers... | Jisch
Aug 5, 2003 6:10 AM | | Likewise - I maintain my bike well. I have found various parts loose down there mainly the chainring bolts. I have been down a long road here trying to fix this. I've greased, cleaned and regreased probably a half dozen times. I've replaced the BB completely. On my last go 'round I wrapped the BB threads with Teflon tape and coated the shell threads with anti-seize. I picked up a torque wrench last evening and found that the BB was actually not tight enough. Still after all this, its still creaking.
It sure sounds like its eminating from the BB/Crank area and only happens when I put pressure on the pedals (i.e. bouncing the suspension while coasting doesn't create the noise). I am now about 99% convinced that the problem is the press fit on the drive side, where the BB spindle goes in. I am going to try penetrating Loctite (green) tonight assuming I can find it. If I can't, I'll use blue.
I'll let everyone know if this fixes my problem. Its really driving me insane. I appreciate all the "try this", its helped a lot, and I really appreciate the link from Randy, that's the ticket (I hope!).
John |
| have you looked for.... | *rt*
Aug 5, 2003 6:41 AM | | cracks in your frame? that would definately cause it to creak.......not that i would wish a cracked frame on you but, hey, it's a great excuse to warranty/get something new! ;-)
rt |
| Have looked, but will look again! | Jisch
Aug 5, 2003 8:33 AM | | Its only 9 months old, but I will look for cracks again.
John |
| check the seat tube & head tube too... | *rt*
Aug 5, 2003 9:15 AM | | don't know what material your bike's made from but alu will throw sound in ways you couldn't even imagine! a crack at the headtube can throw the sound so it sounds like your bb is making noise.....does the creak happen when you are off the saddle? if so, then it's probably not a seatpost/tube issue.....
you've probably already checked all these things but.....
rt |
| yep, but thanks. | Jisch
Aug 5, 2003 12:25 PM | | It is an AL bike - Hammerhead 100x (modified Racer-X). And it does happen when I'm out of the saddle.
John |
| ... and if you're really lucky... | ®andyA
Aug 5, 2003 7:02 AM | | ... a warranty/replacement frame may come in pairs like rt's did! -rotfl!!!
I hope the loctite tip works for you.

| budding weight weenie -----> | *rt*
Aug 4, 2003 11:13 AM | | ;-P i figure, as long as i'm going to throw money at a problem i might as well drop some weight as well. i'm also considering a new wheelset. between the cranks and a new wheelset i could drop as much as 1.5 - 2 lbs......if i went with a SID i could drop another pound but sometimes the weight savings is just not worth it!!
thanks!
rt |
| welcome, weenie | litespeedchick
Aug 4, 2003 1:02 PM | | When I swapped my XT cranks, Shimano BB, and RS Judy for Race Face cranks and BB and RS SID Race, I lost a full pound!!! Only cost me a grand!! Sure, it's an obscene waste of money, but that was in 2000, so if I'd given it to my broker instead of my bike shop, it would mostly be gone now. As is, I still have the cranks and BB. |
| lol! good rationale! | *rt*
Aug 5, 2003 5:14 AM | | if i was willing to part with my X-Fly and go with a SID i would instantly drop more than a pound. however, i wasn't all that thrilled with my sid (it's on my HT right now). actually, i liked the SID but the maintenance was such a pain in the you-know-where that it didn't make the weight savings worthwhile for me.
on the other hand, i can easily see dropping the same amount of weight by replacing the cranks & bb with something lighter and replacing my cane creek WAM disk wheelset with something like the Mavic CrossMax's. my CC wheels are great but HEAVY.
rt - wow, i had no idea i could be such a weenie ;-) |
| Another vote for XT/LX | ScottN
Aug 4, 2003 11:10 AM | | I'm 6'2" 210 lbs and I ride a set of 2001 XT cranks and have no problems with them - drops, long rides, trips to the 'Shore and all that and not a problem.
Put LX cranks on my wife's bike 2 years ago also, no problems yet.
Bang for the buck, LX or XT is a good choice.
