Re: Broken shoulders!

A friend of mine has a worse break than yours, and it's not healing well. However, he's been using a static trainer to keep the pedals turning, as he can ride with one hand. Not sure I'd want to ride with damaged shoulder as you seem to be doing, both because of reduced control of the bike, and beca...

Eye contact is often a good way to be confident (not sure!) that someone has seen you. It's particularly useful when "negotiating" for a driver to shield you from behind, e.g. for a right turn.

Re: Favourite tea shops

I don't know the cafe because it's so long since I've ridden round there, but it's such a popular cycling area that it would be a sad loss. Don't suppose it would do any good to go in there like this? ( Details .) https://www.eta.co.uk/wp-content/uploads/2014/09/Worlds-smallest-caravan-QTv.jpg

Re: Pedal Standardisation

Always is for 531C and 531DB. Other Reynolds tubes may vary (I've got a plain-gauge 531 frame that's 26.4, IIRC, so I'd expect that to be standard for that particular tubing).

Re: "I can't remember your name but..."

Me too. And, in my first club, it was not unknown for a rider to be called by the name of his bike, as opposed to by his own name. Of course, that was when bikes were kept for long enough for the practice to make sense, and riders only had one bike!

Re: Daytime lights

It's hard to see how using lights on a bike in daytime could make that immediate ride less safe, so there's a case for saying "Why not?" The problem, it seems to me, is that it encourages a general use of DRLs. That will mean that car lights far overpower bike ones again, and so cycling wi...

Re: maximum rate of spin

As mentioned already, I don't think that maximum rates of spin are a serious consideration. However, any cyclist involved in competition, for example, would want well-maintained bearings in good condition, in order to minimise friction and other losses that could reduce the actual speed produced for...

Re: Brompton chain

It is very important to get chain length right on a Brompton - but just copy the length from the old chain of course.

Re: Bottom bracket removal

Can you do some photographs, bearing in mind that we're looking for something blocking the movement of the BB unit out of the frame? May be hard to get any useful pictures, mind you, but it's hard to visualise. Something from the left (with the cup removed) and something from below the BB shell (to ...

Re: Shimano bottom bracket axles dimensions?

That's what I understand. Yes, the Pedro's tool just does what you can improvise, but it does it quite nicely and doesn't cost that much.

Re: Shimano bottom bracket axles dimensions?

Is this what you need? Available from various bike shops. Currently cheaper at Ribble. I use one and they work well.

Re: maximum rate of spin

Typical cartridge bearings of about that size are happy at about ten times that speed (or more) The rider is the limiting factor. I believe Sean Yates was clocked going down an Alp in the Tour at 70mph, which is about 110km/h. Pros who are not the best at climbing have to make it up downhill :shock...

Re: How Old is Your Trangia ..

Great when combined with a Primus stove as you needed to carry pans & meths anyway. My Primus dates from the late 70s. Actually it's a Hippolyta imitation, because I was an impoverished schoolboy who couldn't afford the real thing. Although various parts have since been replaced with genuine Pr...

Re: Bottom bracket removal

It's just a sealed-bearing square-taper unit on that bike, isn't it? If it's unscrewing properly as you describe, surely there must be something catching inside the frame to hold the BB unit in? Don't see how else it could get stuck.

Re: Folding bikes - good Brompton alternatives?

Easy enough to pick up a pre-loved (as opposed to pre-abused) Dahon Speed/Vitesse (the basic steel/alu model) on ebay to give things a try out. When I started commuting by train, I didn't want to pay for a Brompton, so I bought a second-hand Vitesse from our very reliable LBS. I liked it but, after...
