jam2 bearing kit

[RustyMTB]

Anyone have a list of frame bearings or know of an accurate kit? I'm swapping out but would rather do it in one go than remove them individually to work out what I need. The trails are calling and all that.

Here we go:
This was generated in Dec'20 for my Focus Jam2 2019, with the 140mm rear travel. I got the bearings from TrailVision, who I highly recommend. Very helpful website, fast delivery and competitive prices when I looked in Dec'20 and since.

Trailvision - Bicycle Bearings

Focus Jam2 Pivot Bearings

6901 VRS 4 off Dimensions 12/24/6 This is a single row deep groove radial bearing.
6903 VRS 2 off Dimensions 17/30/7 This a single row deep groove radial bearing.
3801 B 2RS 2 off. Dimensions 12/21/7 This is a double row angular contact bearing

Note 1: 3801 bearings are double row, 63801 are single row. 3801 comes in two widths, the 7mm is needed, not the 8mm.

Note 2: 3801 –B-2RS-TVH may be the complete description for the above.

Note 3: When buying, the number and the dimensions are all you need to get a bearing that will fit. If you look around you will see various additional letters like LLU, LLB, NTN..... These describe the type of seal. Better sealing costs more money and you may prefer to pay.

TrailVision say that the bearing number and the dimensions identify the bearing. Many manufacturers use additional letters for their own purposes. As at Dec’20, the 6901/3 bearings were £7.99 each. They don’t appear to stock the 3801 right now. Plenty of suppliers on Google.

Nicee! Are we sure they're right? Y'know, 2019 & 2020 being different bikes and all.

You didn't give a year in your original post, which is why I gave dates on my reply. As far as I can tell, Focus do not give bearing sizes on their exploded views, just the apart numbers of bearing kits. Here is the one for the 2019 bike (mine). You can compare.

Thanks Steve, just what I was looking for.
