spartan Posted July 27, 2008 Report Share Posted July 27, 2008 (edited) So yeah i managed to strip the removing threads on my zoo cranks today so imma need a new set now. F**K!!!So i want to try 175mm cranks but also hear that the tensiles tend to break. I dont want to spend to much but if an extra 20 bucks between tensile and deng cranks makes my bike ride better ill go for it.So... do they suck or no??Bear in mind im not crazy smooth but dont do huge stuff either.

Andrew Smith Posted July 27, 2008 Report Share Posted July 27, 2008 yes tensile cranks do SUCK if you only stripped the threads where the crank extractor goes in then just carry on using them and when you want to remove them then that the bb bolt out and spray wd40 or gt85 in the splines leave it overnight to soak in and the whack them off using a rubber hammer job done Quote Link to comment Share on other sites More sharing options...
Nick Harding Posted July 27, 2008 Report Share Posted July 27, 2008 Same as above really. Seems abit over the top to buy new cranks if all you have done is stripped the treads for extracting them. Unless you have stripped the pedal threads then thats different. id keep them as they are. Quote Link to comment Share on other sites More sharing options...
CurtisRider Posted July 27, 2008 Report Share Posted July 27, 2008 As said before, unless you regularly remove your cranks, don't worry (its hammer time). As for tensiles, the original ones weren't all that, they broke reasonably easily and the machining on the side hurt like feck if you caught your ankles, i hated both sets of mine. The newer urban legends appear to be ok, i haven't owned any so i cant comment on durability. The advantage to tensiles is the half price replacement, which is worth alot in itself.

spartan Posted July 27, 2008 Author Report Share Posted July 27, 2008 Ok yeah the thing that im concerned about is that my bb has come loose on me twice in the last 3 days.I use a First bb which is pretty much a try-all but without the sticker. The first time i just took off the crank and tightened the drive side cup which was the loose one, but then at the Bash at the Beach it came loose again which is when i stripped the cranks.So im not really sure what to do about the bb and if im going to have to tighten it everyother day i dont want to have to hammer my cranks off all the time.But i will try soaking them tonight and getting em off.Damn, this is such a piss off though, argh!!

Greetings Posted July 27, 2008 Report Share Posted July 27, 2008 I use a First bb which is pretty much a try-all but without the sticker.The Tryall and First (if it's the one with integrated bearings) are about as different to each other as BB's can get. Totally different designs.If it's coming loose use Loctite. Just make sure that the cups and your frame aren't made of the same material. First came in either aluminum or steel version. From what I remember using aluminum cups in an aluminum frame without any lubricant can lead to chemical welding if water gets onto the threads? As for the cranks I wouldn't change them just because you've stripped the thread. It's pretty easy to remove such cranks anyway, you just undo the bolt and ride until they fall off.

spartan Posted July 29, 2008 Author Report Share Posted July 29, 2008 but see the bb is already loose so i dont want to strip out the bb by riding a stripped crank. Quote Link to comment Share on other sites More sharing options...
bollo you ball-bag Posted July 29, 2008 Report Share Posted July 29, 2008 fil the kettle and boil it.make a cup of teapour the rest of the boiling water over the crank arm where it goes on the bb. give it a bag with a hammerb and it wil just come off straight away.then drink you'r tea. old tea isn't good Quote Link to comment Share on other sites More sharing options...

AdamR28 Posted July 31, 2008 Report Share Posted July 31, 2008 Yeah, works a treat if you pull on the crank arm as in the picture though! Quote Link to comment Share on other sites More sharing options...
Muel Posted July 31, 2008 Report Share Posted July 31, 2008 Sadly only really works for the left crank arm, unless you have a dead heavyweight bashring. Quote Link to comment Share on other sites More sharing options...
