New school headsets and bottom brackets how to fit them!

Just got this headset and bottom bracket and not sure how it all goes together!

The guy in the shop said I didn't need the silver part due to the type of forks

Yep - silver bits a fork race - sounds like yours has it built in already fella.

Second from left pop on forks with bevelled side up and slide forks in frame, making sure they're seated ok.

Far right take out the silver nip-ring and slide the black bearing onto the top of the forks bevelled side down.

Put silver nip-ring onto forks and slide down - this'll be tight, make sure forks and bearings are seated properly.

Blue cap onto the forks and then onto working out if you need spacers etc before you pop your stem on.


For the BB bearings - offer up the bearings on the axle with spacer to the underside of your bottom bracket - you need to do this to work out what size spacer between the bearings you need. with spacer on the bearings should be flush with the outside of the bottom bracket or mm proud of the BB.

When you've got this, slap some copper grease on the outside of the bearings and in the bearing cups in the BB.

If you're using a bearing press then slap em in - if you're using a piece of wood and hammer, put the drive side bearing in first, being careful to only twat the outer metal ring of the bearing (not the plaggy black seal or inside metal ring).

Slide the axle and spacer in, then the non-drive side bearing (put the axle end bolts on to stop it sliding out when you do this) and twat the bearing in. Test to see if the bearings are parallel by turning the axle. If it feels 'gratey' then have a look and see if the bearings are aligned correctly and adjust if they're not until the axle moves freely.

Does it look like I have the crank on ok? just used two covers same size, or do you use the washers on the sprocket side and the cover on the other? Cant get my 2.35 tyre on with pegs due to slight buckle in wheel and being such a tight fit so putting a 2.10 tyre on
