Re: Invisible indicators on new cars.

My problems interpreting lights quickly and accurately are many. There are more than ever before in use at any one time (a good eg being DRLs), speeds are higher, there are several types of lighting (filament, arc, led, laser source, reflector and projector light spread), some lights which go on whe...

Re: Weld/braze addition on steel fork - how much respray needed?

The difference between a skilled welder/solderer can be significant, with a bicycle frame this matters! There are products used which help minimise conduction of heat from the working area, preserving paint really well. Heat spread isn't necessarily less just because fusion takes place at a lower te...

Re: Cleaning a very old 2nd hand bike?

I cleaned up a bike from Cheshire recently with the hardest to remove grot I've ever known. At one point it appeared nearly as tough as paint, but soaking in paraffin applied with a brush did soften it enough to be removed with brushes, a toothbrush and rags. I find there's little which resists para...

Re: Matching tyres to frame.

I was in conversation with a friend the other day regarding bikes and cars. At one point we were discussing how vehicles should have dampers that match the springs. It got me thinking. On a steel bike the frame is, by nature, springy. Am I barking up a tree that’s not there? If we're considering 'p...

Re: Shock absorbing handlebar tape.

Does anyone still use old inner tubes? My dad showed me how years ago, using insulating tape inside out to provide the stick. Then it's some cotton tape over the top, it dries quickly after rain and I adjust the 'softness' to required thorough tube size and wall thickness.

Re: artificial sweeteners; are they poison?

Brucey, I'd apply the same logic and good sense you apply to what you put inside your body as you do your bikes. If you drink something with Aspartame or some other nasty in it then you feel off it for a few days, and doing the same happens again, it should be fairly clear what your body makes of th...

Re: Cycling as an activity during the Covid 19 outbreak

The message that outdoor activities such as walking and cycling is ok has not been understood even by Andrew Marr and Hugh Pymm on tv this morning. Walking. Taking the car to a 'remote' beauty spot for your daily ration is not on, because 1 . You may be involved in an RTA on the way there or back a...

Re: Electric VS Just Highly Efficient Regular Bike?

I've tried various combinations of electric bike as I was curious and having experimented, for me torque sensing is the one thing an electric bike must have. Beyond that, chain drive mid-mounting allows the motor to be geared but I've been surprised there hasn't been a bigger difference over hub mot...

Re: Best car to put a bike in?

depends largely on budget. I mean I'd go Volvo every day of the week - by far the most comfortable thing to drive and with their hybrid engine (if it's in budget) it's a great cheap to run choice. We have an XC60 and love EVERY mile. Personally, i'm going the VW T5 route for bike duties and then ke...

Re: Coronavirus (aka COVID-19) - just how serious?

Does anyone know who's winning in Wuhan? AIUI the closure of streets in the city due to the coronavirus and the resulting reduction in air pollution (itself the cause apparently of respiratory illness) should result in a decrease in deaths from respiratory illness. This is balanced of course by the...

Re: Coronavirus (aka COVID-19) - just how serious?

If you're not too worried, the spread of this new virus is fascinating for several reasons - not least the reactions of a generation in the UK who've grown up being ferried around exclusively in cars and believing a trip to your GP/local hospital is a cure-all, provided you've had the recommended te...

Re: What is Black Sludge (rim brake question)?

I've always assumed the sludge is a suspension of tiny aluminium oxide, aluminium and pad material particles, that it's their small size (talking just microbes and tens of, I imagine) which helps them stick so well. There has been the odd occasion when sludge hasn't been sufficiently washed away aro...

Re: hydraulic disc brakes v cable disc brakes

Last Spring in typical Lake District heavy drizzle there was more than enough power in the cantilevered rim brakes to stop very quickly down a fast hill, more to the point with enough control to bring the rear wheel ri...
