Re: Disk brake rubbing after wheel change

Which brakes are you using?

If they are cable brakes with one fixed and one moving caliper try this. Move the fixed caliper in using the adjuster. Loosen the mounting bolts on the caliper. Squeeze the brake and tighten the mounting bolts. Retract the fixed pad.

Re: maximum rate of spin

do the maximum rates drop off with wear, dirt and so forth in the bearings? I don't really know. Dirt- I think it's irrelevant in the moment, it'll get crushed, possibly damaging the bearing surfaces. Wear, equivalent to lose adjustment in an adjustable bearing? If it's very bad you would get damag...

Re: Orbea Gain D30 - broken spokes in rear wheel

Shouldn't Orbea be sorting these wheels out? There's the start of a pattern.

Re: maximum rate of spin

Wheel circumference is 2152mm (25mm tyre). They'd cover 100,000,000mm in an hour at 100km/h. (100,000,000/2152) - Each hour the wheel would make 46468.4 revolutions, (/60) or 774.5 in a minute. Sealed cartridge bearings are often advertised as being suitable for much higher speeds, 30000rpm for exam...

Re: Islabikes shifters?

There's isn't, it's just a plastic on plastic system, it's a very basic shifter. There's some special grip shift lube you can buy. I just cleaned the grit out and smeared some of the existing lube around.

Re: Islabikes shifters?

I put a slick/die-drawn/polished stainless inner cable and new outer cable pieces on my son's beinn. I also cleaned out the grip shift when replacing the cable. That made it easy enough for him to turn. I had also been considering a switch to trigger shifters for the same reason and have put it on h...

Re: Taken out by flatbed truck

The most annoying feature of these 'avoided' incidents is that the oncoming drivers NEVER complain (no shouting, gesticluating, horns or lights) about the stupidity of the badly misjudged passing manoeuver. They always have a look which says, well you HAD to overtake the cyclist didn't you, so it's...

Re: Guided Bus Way

Today I saw some pictures of bad cracks on the shared use path that runs beside busway, was it on this forum?

No, it was on a local facebook group. Cracks near Northstowe (a new 'town'/housing development northwest of cambridge).

Re: Touring hub: Shimano Deore LX T670

How does the LX compare with similar road hubs? If you have a frame that could take either, or are willing to respace, are any of them with considering as well?
