it is, er, still 'acquiring more patina'. That particular frame may get another quick squirt of rattle can paint just so it lasts through the winter. If it gets done properly, it'll be done next year now.

Re: Giro d'Italia

From what i saw it wasn't the zips they had problems with, it was finding the other hole to stick the 2nd arm up, and while cycling up hill in a breezy wind. While ascending they didn't need to do up the zips, just get the jackets on ready for the summit, and zip up for the descent. I always cringe...

Re: Dia Compe ENE downtube friction shifter lubrication

FWIW if the ratchet parts are yellow in colour, it is quite likely to be a passivated zinc coating on steel. You can test if this is the case by using a small screwdriver with a magnetised tip; if the tip sticks to the part, that part is steel. Copper ease is great stuff, but not on shifter parts th...

Re: Brompton S6L refurb

Are you taking it back to bare metal and repainting? Probably not; the frame, fork and stem will be touched in/locally painted where necessary. The base of the seat tube has a bad paint wear area on it (where the cables have rubbed) but that is the worst bit; a local paint repair will be OK here si...

Re: Five speed freewheels; then and now.

delving in my bits box I came across this; Image01905.jpg which is a 5s with peculiar ratios; 14-16-21-24-28. I think it came out of the factory like this too. I can only think of a few possible explanations for the ratios - they are part of some cunning plan - they are accidental - they were trying...

Re: Brompton S6L refurb

that is not a bad idea. However I probably won't end up doing that because this bike is most likely going to be kept and used for a while and then sold on. Standard specification Bromptons I think sell easily, whereas if there are 'unique modifications' there may not be a concomitant increase in val...

Re: Made to measure touring bike

a custom-made frameset is a great present to yourself but IMHO it is only really worth getting a custom made frameset/bike if a) you would benefit from non-standard geometry or other features (braze-ons) etc b) you are sure that your current riding position is optimised and/or c) you are sure that y...

Re: Brompton S6L refurb

that is a good point; I think other Brompton retailers will often have parts left over from 'instant upgrades' on new bikes too.

Re: Oiling rollers? Request for advice

I don't think that you have an oil port. If the bearings are dry (which I doubt) you might hear the squeaking and then you know some remedial action is required. You can spray a thin lube into the bearing but this might wash grease out rather than put lube in. If you have thin lube in bearings on ro...

Re: Shimano Nexus 7 speed IGH

if you want to make the most of your 17.5mm of axle I would suggest that you a) make sure the anti-axle-rotation washers are on the inside of the dropouts and b) have the axle nuts machined to be 'shoulder nuts' and have them bearing against thick washers with an oversized bore; this should allow be...

Re: List of recent 'innovations' of the cycling industry

Chris King is good (it should be at the money) so is Hope (but I've not used them much myself) and at more reasonable cost I have had good results with the (now uncommon but briefly popular) 'semi-cartridge' designs, in which the bearings look and fit like cartridge bearings, but you can strip them ...

Re: Dia Compe ENE downtube friction shifter lubrication

yes, corrosion-wise, but you may have to clean the residue off the friction washers. GT85 leaves a thin oily residue. However you may also find that subsequent wear debris then sticks to the ratchet wheel (instead of just falling out as a loose dust) and turns into an abrasive, clogging sludge. I wo...
