Mountain Bike Thru Axle Torque

Close with enough force to leave an impression in the palm.

Mountain bike thru axle torque.

The click type and dial type wrenches have more moving parts than the beam and are susceptible to wear and will require re calibration. At first 135mm was the most common rear axle spacing. If it s similar to the dtswiss rws those should be around 15nm. Recommended torque wrenches park tools tw 5 2 2 14 nm or 18 124 in lbs.

What type of thru axle skewer are you using. Park tools tw 6 2 10 60 nm or 88 530 in lbs. By pushing on the axle you can move the nut out to a position that allows for hand adjustment. But wanted to see other s experiences as well.

If it s the type that has a flip over lever similar to a quick release it should be exactly the same as a qr resistance felt at the lever s halfway point when closing. Early cyclocross bikes borrowed the 15mm front thru axle diameter but as disc brakes became more common on drop bar bikes they all standardized to 12mm. 275 lb in 31 0 nm fuel ex top fuel. The torque applied to the axle is not meant to be used for adjusting relative brake disc position even if you observe such effect.

133 164 lb in 15 0 18 5 nm fuel ex top fuel. 85 lb in 9 6 nm hifi. I don t normally use a torque wrench there but have found that s a little tighter than i would have guessed and if i don t torque it down pretty hard it can loosen up. Keeping the axle under torqued is dangerous and over torquing it might damage the fork frame dropouts.

How do thru axles work. The bicycle has relatively light torque specifications 20 inch pound to relatively heavy torque specifications 600 inch pound. Thru axles are also inserted through a hollow hub axle but they re bigger rear ones are 12mm in diameter and screw into closed dropouts. Lower linkage pivot bolt.

When mountain bikes first went to thru axles the standard was 12 142 which was the same effective width as the quick release hubs they replaced. 85 lb in 9 6 nm hifi. You can also rotate the integrated nut to adjust tightness. 350 380 lb in 40 2 42 9 nm rear suspension.

My 2016 specialized stumpjumper 12mm rear axle has a recommended torque of 15nm. Thru axles can also close with a lever and the same rule applies. You should screw your through axle according to the manufacturer s specified torque value range.
