Re: brake cable sleeve for rear ridgeback cable

Your bike looks like the sort that frequently came fitted with pointless a sleeve covering the bare sections of cable between brazed-on stops. In my opinion it is certainly pointless and in some conditions might interfere with the smooth operation of the cable. Provided you have good quality stainle...

Re: Sturmey archer actuator plate HSA470

Remember Rover cars....k series engine cost savings? Accountants never learn. The full story is far worse; accountants rarely can be bothered to understand technical issues so can be easily fooled by vanity projects. K series worst problem from the start was head gasket failure due to small pores i...

They were there last night but not now; I suspect the internet is full currently. They should reappear as global hangovers develop.

Re: Need a new bike.. again.

Is the post a wind-up? [ EDIT : Graham : Probably not, otherwise I would not let it continue. ] It's on cycle chat [url="https://www.cyclechat.net/threads/need-a-new-bike-again.243487/"]Need a new bike.. again.[/url] Then perhaps that's a better place for it and it can thus be forgotten (...

Re: Wheelbarrow inner tube 4/4.8 -8

Best wheelbarrow I've ever owned. Solid and strong, and easy to use ......................... and no pneumatics. What's not to like? ball-barrow = very bad wheelbarrow; v. basic design fault; no pneumatic tyre means it is V hard work with a load on over soft ground (into which the ball pushes) or v...

Re: Road 1X - useful or just a fad?

In 1980 I had been so traumatised by my first experience of double chain wheels (on an awful Viscount with an almost entirely ineffective front derailleur which worked on a rack and pinion - giving pure 2D motion and thus entirely useless - I think it may have been Simplex) that on my next bikes l u...

Re: 1963 National Road Race Championship

Mike Vaughan Cycles (Mike's Bikes) in Kenilworth might be worth enquiring of. I believe it is still run by Mike junior and, assuming his dad is still around, might be able to shed some light. I think Mike senior was running the shop in 1963 and, although I think he was more interested in motorcycles...

Re: hi, Nexus seven hub changing the rear sprocket from 21t to 16t

What are the numbers by the black triangles on the calculator? Those numbers are the "size" of the gear in inches; this means the effective diameter wheel a penny farthing would need to give the same progress forward for each revolution of the pedals. The example set up by Brucey is for a...

Re: Strongest set of touring wheels.

Thanks Colin and Brucey for your considered opinions; they are interesting. I hadn't really thought about other spokes I have damaged which didn't go on to break; I have graunched loads with chain interference and never seen one break at the damage site. The cases I described (not my only experience...

Re: Strongest set of touring wheels.

Most of the responses assume that the initial build of a wheel entirely dictates it's longevity. Whilst broadly I agree with this, it does ignore the possibilities of bad luck and carelessness. The majority of broken spokes I have experienced have broken mid length and show clear fatigue pattern on ...

Re: Are bikes getting bigger?

I am normal height (1.87 m) and I believe frames have got small, mostly due to the introduction of compact geometry and mountain bikes encouraging the wider availability of long seat posts. In 1981 I walked into John Atkins Cycles, in, Coventry, and John pulled a Carlton frame down and said it was t...

Re: Cartridge bottom bracket - shell doesn't need facing. Why not?

The reason for bottom bracket facing with external bearing BBs is that the two bearings are seperate pieces, each screwing into one side of the shell. Thus facing is essential to ensure that both bearings are pulled up to parallel faces and so the shaft should pass through parallel and aligned bores...
