Cheers, yeah the tab fits no probs.
Thanks for the reassurance.

Im not sure there can be a fit and forget solution for bb’s in their current design as the fundamental problem is failure through ingress of water and mud, leading to premature bearing wear. Until the BB design changes Im not sure there will be much improvement.
If you look at great engineering companies, producing proucts for the mtb world like ChrisKing and Hope their basic design is the same (has to be or it wont fit) but the difference will be the sealing of the bearings from the crap we ride through.
I think the bearings are so small so the seals cant be sealed sufficiently – crud gets in and they must be replaced. Stainless and ceramic might last a bit longer but as soon as that grease turns to grinding paste your days are numbered. I know they are quite different but look at the crap that car bearings go through and how often are they changed? Reason? They are huge and well sealed.
Get some designers on the case and make us an everlasting BB!
Im all for regular maintenance of a cheap BB shell with regular changes of decent grade bearings from a bearing supplier.
I guess that doesnt go with the OP query but just my 2p.

Ive tried the maplin gloves and didnt really like them. When I took them back they asked what batteries I had used and they said I shouldnt use rechargeables as they dont have enough output. SO i guess if you kept them fed with a good supply of Energizers (environment anyone?) they may be OK.
Snowboarders use mitts which keep the fingers together and the thumb separate for the whole ‘opposable thumb’ thing. They can be had quite cheap.
Couple this with a cup of soup and a thermal gilet you should be sorted!

Id be looking at increasing ventilation in the loft area.
Dont cover the existing insulation with a membrane as you will cause condensation on the inside of this membrane and soak your insulation.
The condensation isnt caused by damp air leaving your house its the heat it contains causing the moisture in the air in your loft causing the moisture.
So if you have heat rising somewhere you must have some gaps in your insulation.Loft hatch ok?
