Re: 21mm quill stem?

As Brucey says, it should be 22.2mm. 21.1mm only come on some odd (older) French imports and on modernish (horribly) cheap bikes. If your old stem is 21.1 (should be stamped somewhere), then its is probably the case as Brucey mentioned it has been swapped at some point. Hopefully you have proper Gal...

Re: Chain Links And Tool

They are sometimes the same for a given speed, but not always. If I remember correctly, 10s Shimano chains take different joining links from Campag 10s chains (or is this the case for 9s?).I have a hunch 11s are all the same. I'm sure some one will be along to confirm/correct me on this shortly. KMC...

Re: 'zero reach' stem for 1.1/8 steerer

Some dropped handle bars have the tops sweeping backwards a bit either side of the center clamp so reducing reach. If you had a very short stem, say :- https://www.sjscycles.co.uk/stems/100-pro-plt-1-18-inch-stem-plus-10-deg-318mm-clamp-black/ though I have seen shorter that this one - 29" bike...

Re: ladies bike with very low step through

Dahon make a very low stem through folder which might get you mobile for short trips. On their website :- https://dahon.com/bikes/ciao-ei7-5/ The one on the website is electric assist and they don't seem to list a none electric one. That said, a friend has had a none electric version for some years ...

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

Good timing, my grease tin scraping has finally cleaned the bottom of the tin.
I'd like 1 X 500g tub please.
Might have 2 if it helps you get the numbers/empty your tub.

Thanks.

Re: Pedal axle bearings in cranks

Yes. Shimano's 1st go at aerodynamics in the early/mid 1980's I think, 600AX pedals. The pedal platform was on the axis of where the middle of the pedal axle would have been. The bearings were within the crank profile. To achieve this the pedal thread/fitment in the crank was notably bigger than the...

Re: Servicing for rental bikes????

I regularly service company pool bikes, so similar to what you are looking for. Some misc points ;- When a new head of the admin dept arrived, immeadiately all bikes in her remit were to be serviced monthly (I think it had been quarterly before), and any bikes over 4 years old were disposed of (seal...

Re: Butterfly Handlebar - Recomendations

Humpert do quite a variety of butterfly bars, some (+ others) can be seen on the St John's St website ;-
https://www.sjscycles.co.uk/handlebars-comfort-cruiser/
They range from the usual ones, to ones that clamp at the back (so most of the bar is forward of the clamp).

Re: 26" wheels going out of fashion?

Brucey,
Fair point, however....
I didn't say I'd need a new bike, I said it might be an excuse for a new bike. No necessarily the same thing!
Might be an excuse for a Rohloff too....
Getting a new bike can be fun, I've not done that since 1994.

Re: 26" wheels going out of fashion?

I expect 26" wheels will move out of fashion, such is the way the world works these days. So far however, I have yet to replace a worn out 27.5" tyre at work, and hardly any punctured tube replacements, so in the real commuter world they have not filtered out that far despite being on Carr...

Re: Why this design?

Spoil sport, I was hoping for a few random guesses!
Yes, it is a seatylock. The owner put some money up as crowd funding, got the end result 3 years later. Not the most comfortable thing to sit on as you say.
Now its all very rattley on it's pivots, until sat upon.
