Re: Rusty bolts and aluminium fittings...

However, there's no lithium metal in the grease, there is a lithium soap.

Re: tiny smudge of oil on the crank

The B1 chains are very noisy with even slight mismatch in wear. Not sure how long it takes to go away as I just bought a new sprocket and flipped the chainring.

Couldn't you do the same, same chain, reverse the chainring and fit a new sprocket?

Re: IGH lubrication; a smoking gun.

In an oil or SFG lubed hub, how does the lubricant circulate, is it picked up at the bottom and then drains down through the mechanism as it rotates? I have often wondered if any hub internals are designed to aid the circulation, for example with 'scoops' or ribs to pick up some oil.

Re: Genesis Croix De Fer Dent

Not convinced it's worth repainting. Would probably align, touch up and use for a bit before spending any money on it.

Re: Damaged Chain - Which option?

4, check the chain wear. If not too worn, fit a second quick link to replace the damaged link or, if there is sufficient length in the chain, remove an entire inner and the damaged outer (a pair of links) shortening the chain.

Re: Regreasing quill stem and seatpost

I would recommend anti-seize paste, not grease. Copper "grease" is an anti-seize paste with copper particles in it. Lithium based grease on the other hand is a grease, that is oil thickened with a lithium based soap. It is not a paste with lithium particles in it. https://www.bostik-indust...

Re: Pedal tap set

How bad is the damage, how many threads are stripped? That will determine whether you can recut the existing thread with a pedal tap or if you need to put in a thread insert. The insert taps are either 5/8x24tpi or 20tpi. They are not like normal taps, they are longer because they have a reamer to e...

Re: 5kg tub of topline 2000 AKA Dura Ace grease

Yes, please, I'll join the postage group if that's ok as it'll be a while before I'm down that way.

That's pretty much what I was thinking, if the package is crushed or squeezed the wrap provides a bit more insurance against leaks.

Re: 5kg tub of topline 2000 AKA Dura Ace grease

Could I suggest a wrap of wide tape around the circumference, overlapping tub and lid.

Re: Pedal axle bearings in cranks

I thought that with carbon cranks or more advanced forging techniques there is the potential now to house two bearings in the crank with a greater separation, accomodating cantilever loads more effectively. Not necessarily any more aerodynamic though.

Re: 5kg tub of topline 2000 AKA Dura Ace grease

Whereabouts in North Herts, how far from Cambridge? If not too far I'd collect a tub.
