Ensure that your pedals are tightened to at least 310 in-lbs (35 Nm) every 5 minutes for the first few rides. Before fitting, it's also a good idea to make sure your pedal axles are clean (a wire brush works well) then greased before installation.
Similarly, always check crank bolt torque is at least 310 in-lbs (35 Nm) every 5 minutes for the first few rides, then each and every ride after that.
Failure to keep your pedals or crank bolts tight as described above is likely damage your cranks and this will not be covered under warranty.
Please note that the minimum required thread contact between crank arm and sprocket/freewheel is 7mm, and a 1.37" sprocket/freewheel with maximum internal thread diameter 33.80mm (NOT 1.375") must be used. Failure to adhere to this instruction will damage the cranks threads and this is not covered under warranty.

Hi, I have recently bought one of these but found out that I might need to buy a bb from here aswell as the cranks may hav an error with the frame ? I hav an echo zoo Lynx frame. What are your thoughts on this?

Hi Tommy - Clearance can be a little tight on the ZOO!/Echo frames, especially with the Trialtech cranks. Trialtech make a BB called the Sport Spanish BB (Quick find code: 013090) which is 8mm longer than the standard BB in your frame so should give you the extra clearance you need. I have heard of riders filing/grinding the back of the crank arms to give them the extra clearance they need, but the longer BB might be a better bet in the long term. Thanks, Mark
Hi guys Is there any warranty for those cranks or any cranks at all. Thanks

Hi Sergey - these, and all our other cranks come with our standard six month warranty. Thanks, Flipp.
Just had a word with some lads on Trials Forum and one noted that these cranks on a GU 26" are known for catching the brake cylinders? Is this correct?

Hi Alex - thanks for your question. It is very dependant upon lots of things. Rim width, and brake pad depth being the main ones, but the cranks can sometimes end up clipping due to the bottom bracket being 124mm rather than 128mm. We would recommend Echo cranks for use on that bike as they have the larger offset and will remove the issue, though these will happily work on many setups. Hope that helps. Thanks, Flipp.
