Seems to me like an attempt by Orange to keep things a secret - it's not mentioned on their website, most dealers don't seem to have them for sale and it's not that easy to find any detail on them.
I don't see the point in limited editions myself - if people want to buy a bike, the maker should build as many as there is demand for. And anyway the more they buy in, the less they'll have to pay per unit. But I don't see the sense in building a very small number at high unit cost and then not really marketing them.
Basically Orange have reissued the Clockwork, which has always been a nice bike but is hardly cheap at Â£320 for a frame, with geometry for a 100mm fork. They've also got the P7, which I'm guessing is a bit burlier than the Prestige and has geometry for a 140mm form, which is pretty full-blooded. So maybe they thought there might be another market for a classic light steel frame, but they've still gone for 100-120mm geometry, so that bit isn't very classic. Probably a very nice frame, but I don't understand what they're up to.
Clockwork frame price compared pretty favourably with similar steel frames IMHO, maybe 5 - 10% more expensive but nothing horrific.
The new Prestige is on p.11 of the Leisure Lakes catalogue, not very well hidden considering the distrubution of that
I applaude Orange for the release of updated versions of older models. It's exactly what i'd been wanting from them for the last 3 - 4 years. Why take a step backwards when disc brakes and 100mm travel forks make mountain biking so much better? The market is obvious; retro is cool but the majority want to buy in to the culture but retain modern sensibilities.
The Prestige Pro at Â£1150 is perhaps again 5 - 10% above similar specced models from other manufacturers, but hell i'd pay that premium to not have the logo begin with S.
I have a catalogue sat in front of me that asked Â£375 for a Prestige frame in 1993.
