isitafox Posted June 27, 2013 Report Share Posted June 27, 2013 More than likely worn over time as Zoo cranks are pretty old now Quote Link to comment Share on other sites More sharing options...
tom@eastcoasttrials Posted June 27, 2013 Author Report Share Posted June 27, 2013 is there much I can do to fix it or just buy new ones Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 27, 2013 Report Share Posted June 27, 2013 My cranks are exactly the same, I just live with it untill I can get new cranks. Just carry the allen key with you and tighten it every now and then. You could try putting bits in there (someone suggested a piece of alu drink can...) But when iv done this in the past it only lasts a short while and could make the crank splines damaged even more (depending what you stick in) Cheers Quote Link to comment Share on other sites More sharing options...
JanStahl Posted June 27, 2013 Report Share Posted June 27, 2013 You could change their position on the indenting of the BB. Sometimes this help getting a few months more out of them. Quote Link to comment Share on other sites More sharing options...

tom@eastcoasttrials Posted June 27, 2013 Author Report Share Posted June 27, 2013 its not a crazy amount of movement might just treat myself to some new cranks Quote Link to comment Share on other sites More sharing options...
dngr2self Posted June 27, 2013 Report Share Posted June 27, 2013 Put some PTFE tape on the bolts first then get them really tight. PTFE is available for next to nothing at any DIY shop. Quote Link to comment Share on other sites More sharing options...
tom@eastcoasttrials Posted June 27, 2013 Author Report Share Posted June 27, 2013 its not the bolt its the crank arm its self mate think I'll just have to ride them till they die and get new ones Quote Link to comment Share on other sites More sharing options...
gage-mann Posted June 27, 2013 Report Share Posted June 27, 2013 use some old handlebars to tighten the cranks up Quote Link to comment Share on other sites More sharing options...
dngr2self Posted June 27, 2013 Report Share Posted June 27, 2013 (edited) its not the bolt its the crank arm its self mate think I'll just have to ride them till they die and get new ones You said they usually start off ok but then come loose after riding for a little bit. This would suggest there is a little bit of play in the cranks and that's making the bolts loosen. If you use ptfe it'll help keep the bolts tight and reduce the play so you'll get a bit longer out of the cranks until you can afford new ones.In other words it'll stop them being a pain in the arse.

UK_SPAWN Posted June 27, 2013 Report Share Posted June 27, 2013 Yeah same as mine. I jump on the allen key, if I tighten it more it WILL break the bolt. And still a little tiny tiny movment that just feels like a click as you pedal to a certain spot. And clicks back when you get to the oposite side. As someone said up there... change crank orientation also. Like by 90degrees (and ofcourse the other crank lol) this helped me a little.
