Hi, on my last ride I could feel something felt loose on my bike. when I got home I wobbled the wheels. Seems like the rear has movement. Will this just be a case of tightening something up or could it be a different issue? The bike hasn't done loads of miles, it's less than 2 years old. It's a Boardman 8.8 SLR.
Cheers,
John.

I looked at the spec at https://www.boardmanbikes.com/gb_en/pro ... -2021.htmlJohnhewitson wrote: ↑10 Mar 2023, 8:57pm Hi, on my last ride I could feel something felt loose on my bike. when I got home I wobbled the wheels.

and it said Hubs: Formula DC-20 front, DC22 rear
Thats actually refreshingly honest. A lot of vendors conceal the source of their hub by putting their own branding on it.
Zooming in on the pic of the bike it looks like a quick release version So probably this hub Looks like Scott use these hubs as well (Formula hubs are on many brands, including my Specialized MTB) and I found a repair kit for the Scott one... just so I could see the internals. From this I would say it was probably a "cup and cone" hub so probably easily adjustable without having to bash out "sealed bearings" (like some other Formula hubs, mine included)
EDIT: I also found an overall schematic of how the hub goes together If you have not adjusted a cup and cone hub before you could look for the DC22 hub on YouTube, or, more easily, a half decent bike shop should be able to sort this out for you. If the bearings are still ok its a 10 minute job. If the bearings are dodgey though it could take longer. I am pretty certain this is the hub my bro-in-law had on his Boardman and in his case we had to change the cassette body so that was a longer job.
Plenty of other wise heads on here though ... lets see what others think ...
By the way, do you need guidance on how to adjust this yourself? Or have you done "cup and cone" bearings before ?

Have you checked that the quick release skewer is properly tightened?

Re: Rear wheel bearing
A wheel wobbling at the rim is likely to be one of three things:
- bearings/axle assembly
- not secured in the dropouts
- lack of spoke tension

Re: Rear wheel bearing
Thanks for the replies, I've only just got round to it now. Definitely the bearing, think I'm just going to take it to a shop since I've never done it before and think it's best for this to be done properly.
Cheers.

Re: Rear wheel bearing
Looking at zenitb's thorough post above, it is likely that you have cup-and-cone hubs that need a quick adjustment with some new grease. It could be a ten minute job. Alternatively the freehub body that the sprockets sit on could be loose, and that would take a little longer to fix.Johnhewitson wrote: ↑28 Mar 2023, 8:36am Thanks for the replies, I've only just got round to it now.

Re: Rear wheel bearing
It takes a knack to get cup and cone hubs spot on so it is tight enough not to wobble but not over tight causing drag , I have been doing them for a number of years and i now have it down to an art but if you dont have the tools or the experience then it can be easier to let the LBS have it .
