It happened to me, though on a tandem, but even when I thought my rims were not getting too hot. On long descents your rims can get really awfully hot, and thus also your tubes. The patches are the weak spots. Let me put it this way: I will not let my wife or children descend in the Alps with tubes ...

I sympathise: I am currently riding a very ancient bike in the foothills of Jerusalem with 36x28 as the lowest gear. That is hard work sometimes, and if it were not for the fact that this is only a shortish visit I would replace the rings. Not sure what Spa sell but Specialites TA have a triple conv...

How about this one: http://www.cartostudio.nl/fiets/ ? The Alps are crossed by train at the highest part of the route near Kandersteg, but in return you get an attractive ride. An alternative is to use the route along the Rhine, and then take the Spluegen pass (or a bit of the Raetische Bahn) into I...

Spokes come in many different sizes. I think a trip to your local bicycle shop may well be cheaper, and easier if you don't know the size that you need. They can also tension the other spokes for you: spokes break from being loose.

One of the welcome consequences of the led headlight revolution is that one no longer needs environmentally wicked batteries to produce a lot of light. I fitted an Edelux to my wife's Son equipped bike the other day and that light is very bright indeed. It is bright to be seen on the road under tree...

Interesting tests, but I cannot escape the impression that there is considerable measurement error involved. Look at the measurements for the IQ Fly, the Cyo and the Edelux. They all use the same reflector, and yet the measurements for centre and off centre are quite different. Equally, these measur...

See http://www.peterwhitecycles.com/headlights.asp for excellent beamshots of nearly all interesting lights. The only light missing in this lineup is the new B&M Cyo, which in a sense occupies the spot between the Fly and the Edelux. It comes in two flavours, one for more light nearby, and one f...

Because he absolutely did not want to have punctures. There are situations where I do not want that either, such as going to work. He then discovered that the Marathon Plus is rather harsh, so he let out some air. I fear that will not help much, but that is a different matter. Every tyre is a compr...

People differ, and so should their handlebars. However, straight or slightly curved handlebars should always be wider than the drop bar equivalent. I also have wide shoulders, so the Thorn comfort bar suited me fine on the tandem. On a solo bike I would probably have preferred something slightly nar...

Don't spend too little: cheap bikes from chains and supermarkets are crap. I would go for some kind of hybrid with hub gears. The best affordable gear hub is probably the 8 speed Shimano, and it will get you up most hills. The advantage of hub gears is lower maintenance costs. Unlike derailleurs the...

I mostly just put in a new tube. That really is much easier on the road than trying to patch a tyre. I may do that once I am home/in the tent. I don't really like patching tubes, since patches can and will come off when the tube gets hot from braking on long descents. You forget you have patched the...

The new top Shimano hubs are indeed better than Shimano's earlier offerings. The SON 20R, however, is still lighter and more efficient with led lights. Exhaustive tetst have been published in Aktiv Radfahren and Bicycle Quarterly. Just spinning the wheel is not a correct way to measure hub generator...

See http://www.fisroutes.nl/fietsweb/img/fietsweb2008.jpg and http://www.fisroutes.nl/fisroutes/routes.htm for a survey of Dutch routes in the area. The maps would do, I guess. The French bit is relatively flat and uneventful terrain. Riding further east is harder, and more exciting. Willem p.s. thi...
