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.

It looks like the bashring keyways on the crank arm are extended from the 35mm diameter. I assume this means that a standard 35mm bashring will not fit?

Hi Ryan - You're right. The splines are also necessary to prevent the bashring from spinning round when hit. Thanks.
Can I use 'TRIALTECH SPORT FULL BASHRING (UP TO 23T)' on this crank? Is it compatible?

Hi Kim - Unfortunately, the bashring on the Sport Lite crankset is unique to the Sport Lite cranks, so no other bashring is compatible. Sorry about that! Thanks, Mark
Would a HG splined sprocket fit on these cranks, perhaps with a spacer?

Hi Dave - As long as you have a HG splined sprocket with the necessary 'King spline' (the smaller width spline) on it, it should fit fine as long as you space it all out correctly to suit the lockring. Thanks, Mark
hi im in the process of building a trials bike and plan to run front freewheel. ive found a fixed onza rear hub which takes a part cassette. my question is is this possible to run a parted rear cassette with the narrow 3/32 x 1/2 option front freewheel. i have seen the parted rear cassette and jockey wheel before just wonder whats the best of suitable crank combo to buy to run this option. thanks

Hi Barry - Running that kind of setup should be no problem at all. The freewheels we stock are all designed around 3/32" chains so you'd be spot on with that. In terms of crank options, this Sport Lite Splined Crankset is a handy way to go as you've got all the bits you need there in one go, but you could spec your own cranks, freewheel and bashring too if you wanted. For a slightly cheaper setup you could use a pair of cranks like the Trialtech Race Forged ISIS or Jitsie Forged ISIS Cranks, a TartyBikes CNC Bashring and a Jitsie 108.9 Freewheel - this would come to around £105-109 depending on the specific option you chose, so would save a bit of money. ISIS BBs start from around £35, just so you know. The only other thing worth noting is that we stock a few different fixed rear hubs, so if you wanted to go for a lighter and more straight forward option that using the split cassette on the Onza hub, a fixed rear hub and screw-on sprocket would come to around £70 (based on the Jitsie 135HS Rear Hub and the Echo TR Screw On Sprocket). Hopefully that helps - if you've got any more questions feel free to pop us an e-mail. Thanks, Mark
