Lrn2Trial Posted May 7, 2013 Report Share Posted May 7, 2013 Come home the other day and found that my nephew had been on my bike and the pedal was loose but he didn't tighten it up he kept riding ! So I when I got on it and cycled I realised he stripped all the thread from the pedal end of the crank. So Iv'e bought try all Isis cranks for a replacement Quote Link to comment Share on other sites More sharing options...

Lrn2Trial Posted May 7, 2013 Author Report Share Posted May 7, 2013 (edited) If they do will the pedals still fit in ? Because now they can slide in and out because so much thread has been stripped. Edited May 7, 2013 by Lrn2Trial Quote Link to comment Share on other sites More sharing options...

CalopS Posted May 7, 2013 Report Share Posted May 7, 2013 Sell your nephew to cover the cost of new cranks and check your pedals regularly to make sure they are tight! 4 Quote Link to comment Share on other sites More sharing options...
Lrn2Trial Posted May 7, 2013 Author Report Share Posted May 7, 2013 Should have done some research before buying new cranks, I was so close to buying the echo SL 2013, But decided to wait untill I get better. Quote Link to comment Share on other sites More sharing options...
chimpanzyyyy Posted May 8, 2013 Report Share Posted May 8, 2013 did you remove your pedal with easy after this? I have a similar issue at the moment, and my pedal is stuck keep turning in both directions but can't get it off I was thinkin about cutting the crank with the angle grinder to have my pedal back Quote Link to comment Share on other sites More sharing options...
ooo Posted May 8, 2013 Report Share Posted May 8, 2013 I had my trialtechs helicoiled and it lasted about an hour, I guess it works for other people. From my experience I think new cranks is cheaper in the long run, so don't worry about buying them. 1 Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted May 8, 2013 Report Share Posted May 8, 2013 I had my trialtechs helicoiled and it lasted about an hour You still need to keep the pedals tight as if the cranks were new (very frequently), because it's a brand new thread...

Lewis Gething Posted May 8, 2013 Report Share Posted May 8, 2013 I had my Trialtech cranks helicoiled by Tarty and they were good as new, never had any problems after they were fixed, never even a hint of coming loose Quote Link to comment Share on other sites More sharing options...
dave33 Posted May 8, 2013 Report Share Posted May 8, 2013 Helicoils are fine if they are fitted correctly, the hole needs to be the correct size for the tap to achieve 100% thread depth. It's difficult to dril the correct size hole with a cordless drill for example. Althought if used in alloy they can be alot stronger than the original thread the fixing must be kept at the required preload to avoid damage and failure. So not reply the correct application for a pedal which is going to be removed now and again. Your much better off with a solid incert like the 'time cert' style which can be glued inplace. They are also better for a high tourque situation when the bolt or fixing will start to stretch which is when the Helicoil can fail. If you pedal can be pulled out the hole might be to large, in Quote Link to comment Share on other sites More sharing options...

I have a similar issue at the moment, and my pedal is stuck keep turning in both directions but can't get it off I was thinkin about cutting the crank with the angle grinder to have my pedal back No my pedal did not come out easily I had to just keep turning the Allen key until the pedal released, The thread on my pedal was still in perfect condition but the thread on the crank was stripped completely.

Lrn2Trial Posted May 9, 2013 Author Report Share Posted May 9, 2013 that was'nt working, so I cut the crank open with an angle grinder bye bye crank but the pedal is fine Ye my pedal was fine after I removed my with force too I think the pedal thread is steel and the cranks aluminium. But I've fitted Try-All cranks now that are 160mm and my old Trialtech ones were 165mm I'm not 100% sure but I think I can feel a difference or maybe it's because I haven't been on my bike for a few days. So I recommend if you get new ones get the same size. Quote Link to comment Share on other sites More sharing options...
