the only thing that will happen is that the seat comes adrift True, although if that happens halfway down a steep hill it might not be a very jolly experience! Strangely, the top mountings of the seat are only held into the seat stays by friction. There are these aluminium "nodules" which...

Hello Brucey Yes, it is like in that picture from Rob's blog. Mine has four sets of holes, rather than three, which I think means that it is from a later batch than Rob's. He says: I have heard a report from LaidBack of a more recent MetaBike frame going at the mount under the seat, but that was def...

Jumping back a few pages, I think the point about volume maybe got a bit confused. The volume of the tyre, in itself, is not important. It is merely a by-product of the width. I found a little thought-experiment helpful: Suppose you had a 23 mm tyre, and you had a metal air reservoir attached to the...

Hello. I was adjusting the seat angle on my Metabike recumbent on Sunday, when I noticed a substantial crack in the seat bracket, where it is welded onto the frame. :shock: Uh oh! The crack starts on the left and extends about halfway across, along the upper edge of the weld. metabike_seatcrack.jpg ...

I agree with much of what David says. People have different ideas of what "common sense" is. I'm sure there are many people who would regard cycling on 70 mph dual carriageways as contrary to "common sense". (I'm not endorsing that point of view, just saying that I think it's lik...

Thanks for the replies! Similar tests (blind trials with three outwardly identical lightweight/heavyweight frames painted/built up identically, and internally weighted to be the same total mass) were repeated more recently using three reasonably/very experienced cyclists and completely different res...

What chain case are you using? This one: https://www.dutchbikebits.com/chainguards/hesling-original-chaincase Mine kept filling up with sand and silt. Mine has a little hole at the bottom, so any water that does get inside can get out. There is a little bit of dirt on the inside at the bottom, but ...

I know that there are arguments over durability, but leaving that to one side for the moment, is there any consensus over whether steel or carbon forks are more comfortable? I mean, I'm sure there are very stiff and very comfortable forks in both materials, but among forks which you can actually buy...

Get a unicycle!

I have this one: https://hollandbikeshop.com/en-gb/bicycle-lights/union-bicycle-lights/union-headlight-battery/union-headlight-classic/union-headlight-un-4915-retro-led-on-batteries-black/ It's OK. I did find that it was randomly getting flat batteries, but I realised that the problem was caused by ...

How about fitting a chain case? Since I got one a couple of years ago, I have not needed to do anything to the chain. I use my bike almost every day.

What is the main advantage of flexible (e.g. steel) forks? Is it: 1. To take the edge off bigger bumps? 2. To reduce vibration? Is it possible to come up with a rule of thumb for how fork stiffness and tyre size add up? E.g. a stiff fork with a 38 mm tyre feels similar to a flexible fork with a 28 m...

If I search for "touren fahrrad" ... Unfortunately this is not good German. Different types of bike are mostly referred to as "___rad", e.g. Rennrad (racing bike), Hollandrad (Dutch bike), Liegerad (recumbent) etc. "Eine Radtour" simply means a bike ride. It does not n...

I'm thinking about this fork: https://www.sjscycles.co.uk/forks/26-inch-thorn-raven-sport-tour-steel-fork-black-52-mm-offset-b-grade47433/ Does anyone know anything about these forks in general? Is it springy like a brick, or springy like a spaniel? Hopefully the backwards-mounted v-brakes will clea...

I had not realised the Crossrail tunnels are as wide as that. OK, let's suppose that if they were dedicated to bikes, they could transport 28000 people per hour, per direction. The crossrail trains are designed to carry 1500 people each. If they go for 24 trains per hour (in each direction) that wou...
