Lateral stiffness for a given frame weight. And taller riders tend to be more powerful, increasing the need for stiffness.

Re: Do Campagnolo make the best chains in the world?

I wonder if some of these differences are down to bushing-against-roller wear (unimportant unless it compromises the strength and perhaps efficiency of the chain) as opposed to pin-against-bushing wear (which leads to skipping and necessitates replacement). Most chain-wear indicators don’t measure t...

What do you mean by understeer here?

Re: Do Campagnolo make the best chains in the world?

If I were making bicycle chain, my chains would be continuous. You would theoretically be able to buy a chain in any length you wanted, and they'd be "chopped" at the required length. This appeals to my sense of economy, but I suspect you’d quickly find the overhead involved in that kind ...

Re: How to store tools?

Here’s an English version of the Facom toolbox catalogue Psamathe linked to earlier. (It’s a ZIP file that contains a PDF.) What do you think of the BT.9 toolbox on page 149 of that catalogue? (Actually page 8 of the PDF.) The BT.9 is smaller than the BT.11A, since it omits the second layer of draw...

Re: could 'Rinko' catch on here?

Is 12 minutes too long? Are people intimidated by the idea of having to undo as many bolts as that? I think 12 minutes is a bit long, actually. And 12 minutes is assuming good familiarity with the bike. It might take beginners a fair bit longer. I bet it takes a while to get the hang of how to pack...

Re: How Many Bike Shops Do You Need to Visit ...

Are the bike shops in your neck of the woods utterly crap as well? Like, lacking in basic supplies. Is it normal for people to have to travel about 30 miles before they find a half-decent bike shop? I think this is normal, unfortunately. Maybe it was ever thus. The good shops are very good, but the...

Re: How to store tools?

It was in a Leroy Merlin that I saw the plastic toolboxes I didn’t like. They were unbranded, Dexter, and Stanley in order of increasing price. The smell when I opened them (all brands) was unbelievable. Is it some kind of outgassing from the polypropylene? Presumably this passes, but it really turn...

Re: How to store tools?

Lots of good ideas, thanks. The cellar is unheated but surprisingly dry. In truth I haven’t gone through many cardboard boxes, but today the shoebox tore, prompting this thread. It’s a hassle to move tools from place to place in a flimsy box with no handles, and I’m always moving them around, becaus...

How to store tools?

Hello, all. I have a small but growing collection of bicycle tools. Rather than buying a large toolkit of dubious quality, I’m adding bits and pieces as I need them for a job. This ensures I end up with only the tools I actually need. It also means I have a chance to buy high-quality ones that will ...

Re: Leynze Drive mini pump problem

Not a real problem as I will just use it for non Schrader valve tubes but what a stupid idea. I did think of buying another hose but that's a tenner so I might as well just buy another cheaper pump. Surely another hose, if that would solve your problem, would be a better idea than buying another pu...

Re: Shimano BR-R650 cable pull compatibility question

I spy a BR-R650 calliper on this Paris–Roubaix bike (the brake is described as “low-end” by the BikeRadar writer, who of course didn’t recognise it – and might have thought it low-end if he did!). Looks like the braking force with current levers is good enough for pro racers. Valbrona: I think beari...

Re: Hole in new bike tyre

It’s probably a wear indicator. When the hole is no longer visible, the tyre is worn out. Are you sure there’s just one dimple? Normally there would be two or three. On both front and rear tyres.

Re: Shimano BR-R650 cable pull compatibility question

I think you will have to pull about 20% harder for any given retardation level. That doesn’t sound too bad. I found a Shimano compatibility document (link leads to PDF download) that tends to back that up. It says the combination of BR-R650 and current STI levers is officially supported, albeit wit...
