    Best descriptor= linkage hell.
    Think back to the old days of Girvin who became Noleen who became K2 and said enough is enough! My best recollection is that the systems worked well, but not better than your standard twin stanchion forks and when the bushings wore out they made a Chris King hub seem silent.

    Rear suspension is exactly the same as Marin Quad-Link (since Whyte designs them)...read reviews on those and if you like them then get a Marin.

    Looks creaky and noodly. Eww. Imagine trying to find a creaking pivot in that mess.

    They were a really good design, but to ugly to be accepted. And believe it or not, I have been reading that the 4 model needed very little maintenance.

    Preston!

    Those things are collectors items now, four bar linkages at both ends, ah good times. The PRST1's were a bit on the noodly side, they tended to crack at the end of the swing arms. The PRST4 was great, don't know about Americaland but they sold solidly in the UK since they had decent mud clearance and came with Hope kit as standard. They were really nice to ride but I never owned one.

    I see a few a year at events and trail centres, usually with a guy who'd sell his first born before he sold the bike...

    What's with the rear triangle? It looks like it's designed to protect the chainring against rockstrike?

    Congrats on the new bike. If you ever make it up to Santos you won't be hard to spot.

    i love mine, i use for more on road then off. but the few trails i did take it on it was a great ride. i'm heavy 260lbs and i have my rear shock set at near 300psi.

    i will be buying some semi slick and the bike will be complete for me

    I know the PRST-1's suffered from brake dive, did they sort that for the PRST-4's?
    Other than that, they were certainly a distinctive bike, I doubt that there is much out there to rival it for looks (or lack of).

    Following the earlier advice I got I have since posted mine last weekend on the classifieds section here on MTBR. The MTBR site said I don't have enough posts to include the link here but it got listed on DEC 18th. I too did a lot or road time and rail/trail with mine...hence the 1.5" slicks on mine in the pics!

    Not really.

    A better description would be that it's two VPP style frames welded together in the middle.

    It solved the issue of forks and shocks having cack damping in 2003, but it's not 2003 anymore and forks and shocks work now (mostly).

    Had a PRST1 for 2 years then bought the last PRST4 from the factory, Ive been useing it for work for the past 3 years as a mountain bike Guide for Mountain Biking Holidays in Wales excellent bike, not particularly light (28lb) but rides extremely light, and yes with all those pivots its reliable! The front end is silky smooth, far less grief than any traditional forks even today, its limitations.... 4 travel front and back, and its not intended for jumping, it hugs the ground like a ferret, the only mod I have made is wider bars and ditching the crappy disposable Shimano brakes for Hope ones.
    anyone want any info I'd be more than happy to oblige

    Prst4

    Now had mine for 4 years, all suspension Bearings (18 bearings, 4 Bushes,1 Spherical bearing) lifetime warranted (which they honour without question) the bushes (top of shocks) have not developed any play in 4 years with a couple of thousand miles on the clock (so to speak) spherical bearing has been replaced twice (8 a throw) bearings can be replaced with two Allen keys..... can be done without any special tools

    Has anyone tried fixing a fork, let alone on a trail

    Still using mine for guiding as it is so robust yet light feeling to do the all day rides I demand of it!

    Ebay purchase 300 for frame and shocks, I just went for discounted shimano wheels n chainset , avid 1 brakes, my Brooks titanium rail saddle and adapted early Spesh FSR Enduro gaurds as I think they suite it the way the lines follow.

    This bike was built to do a daily 20 mile commute 80% of which is trail, so a bit of a weird spec for a bike.

    I think all up this has cost 600. After a year of use I can say its no different nothing worn nothing creaks or rattles.

    I just grease the spherical bearing every couple of months and it will take whatever you throw at it. Once you get the air shocks dialled in ride is super plush.

    Theres a lock out on the rear shock but the rear end bob is negligible anyway considering the plush ride.

    Weird thing is its lighter than my hard tail and I prefer it to my S works full suss, dont think ill ever sell it, not much else out there.

    Great to hear it, I have no intension of selling mine, I have other bikes but use the PRST for guiding and all day rides, it tracks so well on winding forrest/single track, & I have no trouble riding it for 8hrs+

    The quad link is a phenomenal suspension design. I have always wondered what the front end of those feel like.

    Ive ridden motor bikes for 40 years and always liked front ends to work right, unfortunatly we all get a diet of tele forks so we know no better. In the motorbike world there have been a few attempts to do it right, I ran a Yamaha GTS 1000 for years.
    https://www.google.co.uk/search?q=ya...w=1280&bih=714
    It was so good, kind of following the bumps instead of getting jarred by them. Thats the best way I can describe the PRST 4 front, there is no way tele forks are going to get near because of the friction.
    Once you get the settings right it turns bumps into smooth tarmac.
    The GTS was a flop too!

    Hi,if you need to replace the spherical bearing (I do a lot of Welsh mountain rides on mine) I have just bought a job lot and intend to sell half of them looking for 7.50 a shot, they are IKO PB10's (as originally fitted by Whyte) and now selling for over 15 by retailers, cheers Rich
