Hi Grant! I bought the Fox shocks you put on Ebay last week.
I've owned my PRST-4 from new, it was on the ATB sales website, and I think that it might have been the last one ever made. It has the later tubular front forks, and Deore groupset, but the purchasing process and initial running in mileage went far from smoothly.
The bike was delivered to me in a box, with the wheels out, but it was apparent from the start that the front wheel offset was wrong, as the central rolling axis of the front wheel didn't match where the centre of the spherical bearing was, so the forks and wheel were dispatched back to ATB sales, and a few days later replacements arrived.
After only a few road miles, the spherical bearing failed. The outer aluminium ring stayed put in the front wishbone, and the bronze bush, and spherical part moved upwards, wrecking the top hat, and allowing the wishbone to wear on the fork. Grrr.
At this point, I realised that this bike had obviously been thrown together as a 'demo' bike, and a full stripdown commenced, just to make sure there weren't any more nasties lurking. I gave up on ATB sales, as they never answered the phone, and when they did, claimed that there was never a problem ever with any of their bikes!
On re-assembly, the Hope minis were binding up, because the disc to pad clearance relied on the thickness of paint on the fork bottoms, and after having been apart a couple of times, this disappeared, leaving the front brake binding on when it got warm.
I'm sure that there were a few more things, but fortunately, I'm an ex engineer (once an engineer... etc.) so gradually, all issues were sorted out. Fortunately (again!) I'm an enthusiast for engineering oddity, so stuck with the bike, because I had always wanted one, from the first time I saw one back in the day at Scotby Cycles in Carlisle.
I have no doubt that had I paid full price for mine, my patience would have worn thin, and I would have returned the lot to ATB sales. They are a great design, some might say a classic, but marred with shocking build quality, and some unfortunate choices for the minor components, which spoil the whole. But, persevere, and you will find something with a very different look, and charm by the bucket load.
Unfortunately, I don't think that I'm typical of the sort of person who bought them, and the got (and deserved) a poor reputation, they obvously cost a boat load of cash to build, and in looking so left field and oddball, the market was never going to be that large. By the time I bought mine, I think that all the folks who were going to buy one, had done so by then, and the old stock had been hanging around at ATB sales, who just wanted rid. I bought mine, new for £1000.
