Hello Samuel D I started listening to the podcast, although I only got through about 20 minutes. I'll listen to more of it when I have time. Have you come across JBike6? It is a program in Matlab, which calculates the stability of bicycles based on wheelbase, weight distribution, trail, wheel interi...

I have a saddle called Lepper Tour. It is a mattress saddle, which means that there are springs running from front to back underneath, as well as the two springs at the back. The springs really work! I especially realise this when I ride another bike that does not have a sprung saddle. If I put my f...

Hello all. Helmet debates usually seem to produce more heat than light, but I found this debate quite enlightening! Going back to Horizon's original post, I read the long Guardian article. Whilst it was interesting at points, I disagree with the author's main argument, and thought it was a bit daft ...

Hello Utility Cyclist

Do you prefer a slow or a fast cadence?

Is this bike now sold?

Hello Utility Cyclist

Do you prefer a slow or a fast cadence?

one of the most comfortable bikes I own has 753 frameset and a very light wheelset. Do you think that the light wheels are important in keeping the unsprung weight down, so that the "frame suspension" can do its job? People argue back and forth about whether lightweight wheels are worthwh...

I wonder if the weld at the rear of the bracket will have been unusually stressed whilst the front one has been cracking?

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 ...
