I have these on both my gravel bikes. The set on my Spesh Diverge lasted 18 months before the bearings became really stiff, I have just this afternoon swopped out the ones on my Revolt X, at 13 months, again stiff to backpedal and on investigation the bottom one was pretty stiff to turn by hand without the chain on - that bike does see mankier rides.
maintenance wise they get a regular wash (muc off or similar spray on, but not much) and immediate brush down and rinse with rest of drivetrain when required, I haven’t lubed them.
I have been buying the SRAM OEM ones from Tredz or similar, usually about £25 a set. Is this just the way they are, would a regular squirt of lube help, should I pay a bit more for ones with longer lasting bearings ?
thanks

Just buy some bearings for a few quid and replace them. Very easy job.

Replace the bearings. Not a lot of money. Think our last batch came from Trailvision

Brill, will have a look for bearings, presuming they push out without a specific drift tool ?
any links to bearings please ?

Push out easy. Buy ours in 10s. Will try and find link but it may be tomorrow

I’ve just opened up the bearings, cleaned and regreased them on a GX eagle that’s been sitting around. Dead easy, but I suspect changing the bearings is a better long-term option. As above, they’re a few quid each from the likes of Wych bearings, but I wanted to free mine up today.

The bearings are moulded in so there is a very small lip of plastic over the edge but they will drift out easily enough. I bought some NTN bearings to replace mine but then with new bearings in the shifting went to pot so the whole lot is with SRAM currently awaiting a warranty decision…🙄

No special drift tool needed. Just some sockets and a vice.
626 2rs I think.

Fill the new bearings up with grease and be more judicious with Muc-Off, it's a b****r for stripping out lubricant/grease.

Mine have needed the seals off, bearings cleaned and re greased a few times.

Ive always done the following with Sram jockey wheels when they become stiff
Remove them from the mech, prise out the seals, next prise out the rubber bearing race, this leaves the bearings in place making them easier to clean
Clean the bearings and rubber bearing race with isopropyl alcohol, 9 times out of 10 they come up like new, allow to dry, refit the rubber race and then grease them with your choice of grease, refit seals, refit jockey wheels
Been doing this for 10 years now, as you have already ordered new ones try cleaning the old ones when you swap them over and then keep them as spares
