Sturmey Archer for the win. 1x3. Once you have ridden a fixed gear, you realise you can comfortably ride with a cadence anywhere between 60 and 120.

Too late for the USE shim, I've ordered a Cane Creek! Thermoplastic would prevent stuck posts, which is an additional win for the USE shim.

Ha, overlapping posts, I edited mine above as I bought the shim from BikeInn just now. Makes sense now, regarding the fatigue characteristics of aluminium vs steel. I will keep an eye out for a 30.4mm Thomson. This is going to be a well dressed Rockhopper. I've bought some matching coloured Z3's...

I kind of suspected this, I've ordered a 30.4mm Cane Creek shim from BikeInn. The frame is steel, but its pretty light for a basic mountain bike frame at 2.2kg. Its the last of the steel frames Specialized made I think, double butted Ritchey Logic...seems similar to the Rocky Mountain Hammer...

I'm building up a retro Specialized Rockhopper FS for my son, and the original seatpost was a 30.4mm boat anchor. So I bought a seatpost shim off Ebay, a Truvativ Husselfelt. I'm concerned that its only 6cm long. However, its nicely machined, and being from Truvativ, I'm guessing its been...

did you sell the headset?

have you still got the forks, I could use these to fix up some Z3 Lights, swapping out the internals I think

did you sell these....I've just bought some blue Z3's and one of the adjusters is stuck on maximum pre load

Sorry, I now see no dents. If this is available still, I would buy it.

I'm interested, any dents anywhere? I had the silver and green one, back in the day, and when the downtube cracked, was given a blue one by the local shop which had a massive dent in the seat tube. Nowadays that would have bugged me, back then, I just rode it.

I'm interested in the headset

The rebound cartridge is screwed into the bottom of the fork, so when the pressure builds as the fork is compressed, it must be pressing against the sides of the rebound cartridge, so the cartridge walls must be pretty strong, as otherwise it would be possible to crush the rebound cartridge. How...

I'm going to revise my guess that its bottoming out. Copilot suggests topping out on the rebound. Makes sense to me as the air in the top of the stanchions must ramp the spring rate up.

I thought the cartridge in the Z2 was just for rebound, and the compression is fixed and controlled by the square ports at the bottom of the stanchions, which force oil through them when the stanchions compress into the lowers. I'd be very surprised if that flimsy cartridge is used to control...

It strikes me that the bottoming out on a major bump may not due be to the spring, but instead is down to the compression damping being insufficient. I just wonder if you are doing a rough section on a hot day whether the oil can get too thin? I've never messed around with oil in the past, as I...
