Thru Axle and Lubrication


Active Member
I can't find any mention in the Specialized Turbo documentation on care of the thru axle. Is it supposed to be greased regularly? After removal and replacement of the wheel? Anyone ever had a bike with a thru axle before?
Good question MarcD. I've never owned a thru-axle bicycle before but assume you'd want to clean it and use grease as with other skewer style solid rod axles? I'm not a bike mechanic...

I found the Turbo Owner's Manual online and attached it here for reference. At one point on page 21 it says "Clean and grease moving parts (excluding brake surfaces) arrording to instructions from the manufacturer." which must apply to the thru-axle? Might be worth taking it to your local bike shop and asking. If you find out, please report back here, I'd love to know the proper may to maintain it.

Also, page 8 says "Ensure that the wheels are securely fastened in the frame and fork. Check that the wheels and thru axles as well as all important nuts and bolts are secure (see page 24)."

Today my local Specialized dealer told me thru axles should be lightly greased on the threads to prevent seizing, and if some grease gets on the axle itself when inserting, no harm no foul. This applies to all thru axles, e-bike or otherwise.
Mine was greased when I removed it last Sunday. I have not regreased it but I think the grease on it was still sufficient. Still, good info here. Thanks.
