Re: the art of bicycle folding/packing for transport; modifications for rinko etc.

If you simply remove the wheels and strap them to the rest of the bike you have a bundle that may be allowed on trains with less hassle than a complete bike https://i.pinimg.com/736x/65/d3/35/65d335e0dd1325a0861303bfdc4111e0--bike-bag-compact.jpg I tried the above this morning. I don't think the pi...

Re: Can I permanently run tubeless tyres with inner tubes and new tyre recommendations?

I have run tubeless tyres both with and without inner tubes, on tubeless compatible rims. They work just fine with tubes. I have not run them on conventional rims, but there is no obvious reason why that should not work when tubes are used. The tyres in question are Specialized Roubaix Pro which can...

Re: Rolling Resistance measured on road

So, what next? I'd like to test some wider and narrower tyres. However I have a very limited collection of odd tyres to choose from and I cannot afford to buy a shed-load of tyres purely for testing. Voyager Hypers are popular with some on this forum and I have one in size 37-622. Is anyone interes...

Re: Rolling Resistance measured on road

mad thought; the rolling resistance forces on the tyre are certainly not insignificant at reasonable load, and ought to be easy enough to measure, provided these forces can be isolated. The main problem is that the aero forces on the bike are also large (and getting larger quickly) at speed. They a...

Re: Real world rolling resistance.

I made a determined effort to measure real world rolling resistance last year: https://forum.cyclinguk.org/viewtopic.php?t=123795 My main conclusion was that the force involved is so small as to be inconsequential for most, it's certainly very difficult to measure reliably! You will probably be able...

Re: Anyone dabbled in Make-Your-Own-Gear ?

This is so impressive. A skill I wish I had. Everyone has to start somewhere. I bet there is something you could make. Make it, you will learn something in the process. Then try something a little more challenging. Your skills will improve. Repeat. A little motto of mine: "The only barrier to ...

Re: Anyone dabbled in Make-Your-Own-Gear ?

Making your own gear is both time consuming and expensive. The majority of cheap consumer goods are now made in China, so one way to obtain cheap materials for your project is to purchase directly from China (eg alibaba). Some prices are astounding eg ten PCBs for $2.00 I only decide to make somethi...

Re: cycliing and ageing

So that's a digression, but the tubby chaps doing the sportive I think had come quite far as they were heading to Woking station whereas the ride started in Cobham, there seems to be a thing of 'event' cycling in that some people doing these things perhaps only ride once in a blue moon. Whereas the...

Re: chain wear; another spot on the graph?

Chain lube + road crud closely resembles and imitates the grinding paste I once used for grinding cylinder head valves by hand. Regular chain cleaning is essential for prolonging drivetrain lifetime, it's just such a messy job. I have full mudguards but am also considering a chainguard eg SKS Chainb...

Re: Why the sudden urge to ride bikes on gravel?

There is nothing "sudden" about it, I and plenty others have always ridden bikes on gravel and other unpaved surfaces. This was my first "gravel" bike, 10 speed I'll have you know :lol: It's a bit damp out there - have you got the bike stopped yet? :lol: yes, no chance of a fron...

Nice though that is I was meaning the power bank :lol: Still very much a work in progress.
