The WheelsMfg BB30-24mm EBB in GF's SSMTB didn't survive a week in Swanage including Dorset Gravel Dash a month ago. NDS bearing rough, DS bearing won't even move.
WheelsMfg offers a 1 year warranty on the standard Enduro MRA2437LLB 24x37x7mm angular contact bearings. Think I bought this EBB 14 months ago. Ffs.
Best price for a pair of MRA2437 seems to be £25.50. The stainless steel SMRA2437 are about £42 a pair. Are they worth it? May also need to invest in a bearing puller, as the hole in the body of the EBB seems to be about 24.5mm, so not enough bearing available to drift out.

GF has decided SS is fine for her various commutes, so I'm planning something in between her two current SS options:
- Pompino, On-One Mary bars, Avid V-brakes, 35mm CX tyres, toe-overlap.
- Chinese carbon 29er, Fox 32 Fit4 forks, BB30-Eccentric adapter, Easton Monkeylite DH risers (uncut), Continental MountainKing 2.2 on Velocity Cliffhanger rims.
She's using Alpkit saddlebags but wants something with decent space for a framebag and ideally bosses under the downtube for a tool pod to avoid rummaging.
Best option we've seen so far is a Genesis High Lattitude. Size 17.5, same as her Caribou, but the next size up might be better since she'll fit bars with less wiggle than the Caribou's stock bars.
Projects+1.
- Pompino, On-One Mary bars, Avid V-brakes, 35mm CX tyres, toe-overlap.

On-one's sprockets look just like Andel's.

Andel made On-One's HT2-style 144bcd cranks, so I'd guess all of OO/PX's ownbrand/"Holdsworth" toothy stuff is Andel.

I thought a lot of the nahbs bikes looked a lot smaller, closer to 1:1 gearing.
Gear inches ftw.
559 + 2 * 2.2 * 25.4 = 671mm = 26.4" overall diameter
So 32:16 on 26x2.2" = 52.8"
559 + 2 * 3.8 * 25.4 = 752mm = 29.6" overall diameter
52.8/29.6 = 1.784
34/19 = 1.789
622 + 2 * 3.0 * 25.4 = 774mm = 30.5" overall diameter
52.8/30.5 = 1.731
33/19 = 1.737
Also, 32:16 is classic SSMTB race gear, not "go exploring, ride up the Eiger" gear.

Emma's new SSMTB, ready for a test-ride 3 months before SSEC2017, which I entered us both into but didn't tell her about until I'd bought this frame.
Emma doesn't like racing, but has been wanting a non-fat MTB that fits her better than her Voodoo for a while, and a singlespeed bike gnarlier than her Pompino since she started riding that offroad... Two birds, one stone.
Used Chinese 29er with BB30 shell
WheelsMfg BB30 EBB
Fox Factory 32 with FIT4 internals
Velocity Cliffhanger 700c i25 rims
Hope Pro 2 (non-Evo)
Easton MonkeyLite DH carbon risers.Todo:
Upgrade cranks
Find front XT M8000 brake to match the rear.
Find an appropriate saddle
Remove Cannondale graphics from seatpost (using acetone?) or fit a dropper.
Find bungs that will fit inside the ridiculously thick-walled bars -
