Would it seem excessive if you had studied sociology or humanities instead?

Yes, its possible. I've done the same thing myself three times, I've also converted a hub only frame to deraileur gears. Possibly to the second question, it all depends on your bike maintenance skills and what sort of rear drop outs your donor bike frame has and how you view your time... ....other t...

In general for any given behaviour by the other party you're less likely to cause injury by travelling slower into that situation: there'll be more time and space to avoid a collision, and there'll be less kinetic energy that's going to end up somewhere if there is one. If you can't see around a be...

Why did you think going around a blind bend at 13-15 mph was acceptable? The speed of the OP is rather irrelevant, the collision would have happened if he'd been doing 5mph, the scooter would still have been doing the higher speed. I almost came a cropper on a corner yesterday doing about 5mph when...

Thanks very much, speaking as someone who has cycled often, but not that far, this year, such photographs are always a tonic

Just had a quick check on mine, 406 Jubilee with a 105 11-speed mech and a 34t largest sprocket. With the chain in bottom gear, not only is the bottom of the mech cage only 32mm from the ground, the inside bottom of the mech cage is only 13mm from the tyre at its nearest. No wonder chains get crapp...

I think steel bars are much more resistant to wear than aluminium alloy ones. Unfortunately tubular steel racks tend to be relatively expensive but maybe you can find a cheap one? I'd recommend tubus racks - I bought four second hand from this site over the course of about 7 years. The last one I b...

Lastly, just a thought. Is it just us cyclist who keep things as 'essentials spares' even though it's old technology and you'll probably never use it again, but you want to keep it 'just in case', or is it just me. ..um..no, both vintage car and motorcycle owners and those with an interest in vinta...

Hi Kit, I afraid the postage would cost more than the sale -they are fairly hefty and don't fold sadly! Ian Yeah, that's understandable. But at 10 pounds for the pair and if a 15 pounds was added for postage costs and the hassle of posting you'd still come under the list price of 25 pounds for a se...

What happened to the old 'reflector on a stick' (sorry - I can't remember the correct name), as they always seemed a good idea.. I still use mine - although its arguemented with a fairly up right position and a bar end mirror sticking out my right side handlebar end... I get motor traffic giving me...

Public access refers to anywhere the public has access, law changes in the 90s determined this , can’t remember the year, but I’d did fall foul of it in 93, with motorbike and a failure to display a tax disc. I had removed it at BMF rally. The police ticketed, my solicitor said it was correct as it...

Is it a legal requirement for a cyclist to use lights when cycling on that sort of cycle path? Yes, during the hours of darkness. Thanks. Do you have a link to the legislation or case-law? On another thread - I think it was entitled cycling and laws, I covered this. There are there several previous...

I am disappointed but not surprised to find that some posters feel able to dismiss Risk Homeostasis whilst clearly not bothering to find out what the theory means. What, you mean the safer you feel the more likely it is to take risks? Never heard of it.... But yes....you only have to look at commer...
