Re: cargo bike - any good?

there are two separate chains, and an idler shaft with two sprockets on it. Oddly enough this is probably more efficient when running in the 'cargo-bike' configuration than in the standard wheelbase configuration. In the electrically assisted version the idler shaft is the location for the assist mo...

Re: Quick check - servicing TRP Spyre mechanical cable disc

yes very easy to replace them. Usually the thrust bearings just get rougher and rougher rather than fail altogether. It is also possible to add fresh threadlock to the pad adjusting screws; a fiddly job but it is possible. NB by the time the thrust bearings are rough, it is too late to do much with ...

Re: Quick check - servicing TRP Spyre mechanical cable disc

no need to loosen the caliper mounting bolts when adjusting Spyre/Spyke pads for wear. SOP is to back off the barrel adjuster, then wind the pads in (both sides, i.e. two adjusters, ideally an equal amount eg 1/4 turn each) so that they are just touching the disc (easy if the wheel is turning with t...

Re: Viner Mitus Disc Anniversary gear cable change

yes frames like that can be a PITA. Near the bb there is either a short piece of liner (which you can dislodge with impunity) or a much longer piece of liner which ideally either a) needs to be engaged with the holes in the frame (i.e. the entry and exit points) or b) needs to have a cable running t...

Re: Tubeless tribulations

so is 'the leak near the valve' because a) the valve is not sealed against the rim or b) the valve assembly is not correctly put together (eg core loose) or c) because the base of the valve is interfering with the tyre beads and preventing the tyre beads from seating somehow? In the former cases (a ...

Re: Spoke Re-use: Sorting insides from outsides

re x2 vs x3; you would need different length spokes for x3 so with the spokes you have x2 is presumably your only choice.

Re: a nasty surprise for someone....?

regarding 'user serviceability' , it kind of depends on the user as well as the mechanism itself. And how often it is likely to need fiddling with; there is a 'consequence' thing going on here as well. Normally a failure to maintain a brake leaves you less one brake. However the same failure twice o...

Re: Spoke Re-use: Sorting insides from outsides

I'd probably (given the choice) build that wheel x3 not x2 and I'd have the outside spokes 'pulling' unless it was a disc brake wheel in which case I'd have them 'pushing' on the NDS.

But there is more than one way to skin a cat....

Re: Sturmey Archer Sprinter Elite 5-speed - modern replacement?

dunno. Arguably the only really good shifter they have ever made is a trigger shifter. This ain't perfect by any means, but it is fairly obvious when it isn't working properly, you can see all the moving parts. A drop of oil every now and then and they last for decades. Older (most twin toggle model...

Re: 1x11 gearing on a bent

….I currently have an SA CS-RK3 dual drive IGH on my Nazca Paseo. In operation I quite like it, but in reality a shift of the IGH is only equivalent to 2 sprockets on a cassette. And unlike a Rohloff you still have to plan which ratio to stop in anyway..... The IGH range in a CS-RK3 is 178%. You ca...

Re: Shimano Brake Blocks

bedding in does three things 1) conditions the rim surface to the brake block (often the rim is coated in a very thin layer of brake block material during dry braking; wet braking changes all that and you basically have to start again) 2) wears the surface of the brake block so that where it touches...

Re: Is there a multi impact helmet?

a 'polystyrene soup dish' not much different to a cycle helmet can meet all the primary impact tests required for a motorcycle helmet. The main exceptions are that the motorcycle helmet has to cover more of the head (esp at the back of head near the neck) and is also subjected to a 'spike' test whic...
