    DT Swiss 240s Road Hub Maintenance

    I have 240s front and rear road hubs. The, manual indicates to service the hubs yearly. However, depending on the rider, this could mean 1000 miles or 10000+ miles. Is there a rough mileage guide for servicing these hubs? Also, it does not appear that the front hub can be serviced other then replacing the bearings. Am I missing something else that should be serviced?

    You can clean & re-lube the drive ratchets and replace the bearings. The re-lube should be done when the hubs get more noisy. That's a no-tool quick operation. The bearings won't need service until they are worn out. They list a special tool kit for hub overhaul. I never did this on mine but I'll bet the bearings can be replaced without it - all except the one behind the ring drive, for which the special tool will be needed to remove the ring drive.

    One of my ratchet rings started to stick in the free hub body at around 9K = 3 years. I think I will service them a little sooner next time; 3K is probably about right. If you do a lot of really wet rides you may want to service them twice as often. I noticed they were getting pretty loud at around 6K.

    I know this is an old thread, but can anybody tell me how to disassemble the front hub? I cannot find images or videos and you cannot do it with allen keys. Am I missing something? Thanks!

    'brifter' is a lame word.

    axle vise, they pull right out. bearings are installed/removed like any cartridge bearing. basically the same as the rear hub.
