Oooooh! A chance to dig up a bit of my old knowledge from the years I spent studying metallurgy (and which I've never used since).

The magnetic element of steel is a crystal called martensite....

There's no straightforward answer to this. My previous regular commute had a Campy 9-speed groupset and I found that the chain lasted me about 10,000 miles. My new commute came with SRAM Force 11...

It's tricky. I find that if you loosen the bolt, centre the brakes and then tighten the bold that action tends to pull the brakes off centre. Try and hold the callipers as you tighten to prevent this...

Interesting question. The problem is just because something has a fancy name it doesn't mean it isn't a completely natural product. One classic example is that the first ingredient on my pot of Assos...

First of all, lucky you living in such a stunningly beautiful part of the country. My daughter lives in an area of Scotland that certainly rivals the Lake District but is far less accessible (for me,...

You obviously aren't getting enough punctures. I suggest you go out and get some more to even things out.

Actually, I'm pretty sure that you can get the tubes of cement by themselves. Also, I'm...

Yes, I had this on my Ksyriums. You can't just dribble oil in either, it needs to be serviced.

I'd agree that for that bike I'd be inclined to go with Campy, but what's wrong with SRAM? Personally I'm very happy with it.

I, too, was in school when we started switching to metric so I'm pretty comfortable with either. I don't what Canadian currency was like but I'll bet you didn't have to cope with a stupid system...

I agree. Not being familiar with that road design it's hard to interpret the pictures but surely he must have hit the fence from the railway line side or the fence would be down the other way.

Whilst this is true you'd probably have to drill out the valve hole in the rim somewhat to get the valve through.

If you think Presta valves are bad you've obviously never encountered the Dunlop...

How does that work then? You hit something so hard it makes a hole in actual tyre?

I'd never had pinch flats for years and then had two quite recently. Since then I've been paying a bit closer...

It sounds like you had a 'snake-bite' or pinch flat which is normally caused by not having sufficient air pressure in the tyre. It's certainly true that going tubeless will stop you having that kind...

I've noticed 1 but not 2. It's a good creme - I've been using it for at least fifteen years now - although the formula has obviously changed as it's been through two colour changes in that time.

I like the Fizik Arione but it's an expensive saddle. When mine broke and I decided I couldn't afford to replace it a friend suggested Fabric. They make their saddles in a differing widths and...

My understanding is that, for 11 speed, the spacing on Campy and Shimano is the same.

I don't think it's as simple as that, though. I think a lot of the issue with cars is that the air intakes are nicely positioned to draw in air from the exhaust of the vehicle in front. There's also...

We don't really get extreme cold where I live. The coldest is typically -2 deg C (28 F), which I'm happy to cycle in. Rain has been something of an issue lately - for about a month it seemed like it...

At last, a cool use for Strava

A cyclist has taken nine hours to pedal a route in the shape of a reindeer (https://www.bbc.co.uk/news/uk-england-50727330).

You're quite right about 'spelled' - I knew something wasn't right as I wrote it - but it's definitely 'tyres', not 'tires'. That way we can't have any lame jokes about bikes being two tired to stand...

I had to look up what a charley horse was. I guess it's what we would just call a cramp. As they say, two nations divided by a common language.

My only thought would be that if it's riveted then it may be non-standard in terms of sizing. Chainrings use two or three different bolt circle diameters (BCD) so you have to get one with the correct...

Yes, I do miss the 'organic' look of the old Campag crank sets. Most of the modern ones are pretty hideous and Shimano cranks are frankly horrendous, in my view. Another reason why I went with SRAM...
