Squeaker. Thanks again.

Their claims for this "maintenance-free" linkage package seems rather extraordinary.

PS : its a 1999 East Peak. So 16.5 yrs old

Back in 2011, I did not bother to get any of the suspension bits replaced via Marin themselves ( due to unhelpful Marin dealer [UMD] ).

Instead I got the Fox shock mounts and bushes replaced via an Ebay seller - J-Tech. That cost £28 approx . . .

The play in the suspension was "good enough" after the J-Tech parts were fitted so I just cycled on for a few more years, until . .

Five years later . . . . the play in the rear triangle must be around 10mm each way at the back of the rear tyre.

* The other Marin dealer in my area took my phone number and promised to give me a ring once he had enquired about the suspension parts.
** No call or voice message ever received.

*** Thus visit to the original UMD ( from 5 years ago ). They made a long phone call to Marin while I was in the shop revealed :-
**** Original receipt of payment for the bike would yield suspension replacement parts under warranty.
***** Marin had parts in stock.
[ As you can imagine this raised my expectations ! ]

Once informed that the parts had arrived I took the rear triangle down to the shop, to have the bearings pressed in by the pro mechanic.

***** There were no other parts provided apart from the pair of bearings. And that is/was all they could provide [ not even the main pivot axle ! ]
****** Marin did not stock any of the old suspension parts, the bearings had to be obtained from another supplier ( but were paid for by Marin ).

[ This seems to be rather inconsistent ! Between the two visits the story has completely changed. ]

I will see how good/bad the suspension is once they have pressed in the new bearings.
I do have a couple of pre-used main pivot axles, on standby, that I might need to bring back into use.

I am told that there is no possibility of replacing any of the other suspension parts where metal can move against metal.

I'm hoping I get 3 more years out of this frame before it is unmaintainable scrap.

Lessons learnt
===========
Suspension frame components wear out - rather rapidly.
Modern bikes that have a new model every year are at risk of leaving you with unobtainable parts in the medium/long-term.

I probably won't be buying another full-suss bike.

No problem unless the shock or rear triangle pivot point bearings fail catastrophically :roll: The shock bearings belong to the shock (as the original Fox shock was condemned as 'unrepairable' a few years back, I'm just in the process of fitting a spare SSD225 DT Swiss shock to mine - the attachment bolts essentially clamp the shock's bushings into the frame) and there are only the 2 rear triangle pivot bearings, so you should be good to go for another 16 years 8)

PS: what front fork do you have? I've run an 80mm Marzocchi Bomber air shock for years (the original Manitou is still awaiting re-deployment) - always thought I should have bought a 100mm version...

PPS: been looking at improving the old girl: longer stroke fork, wider rims (to get a 2.4 happily on the front), disc brakes, that sort of thing, but my wallet keeps saying 'no, look at what you could buy new for that' or 'what about a fat bike' :lol:

Thanks for the reassurance. I will report back once the bearings are pressed-in and I have reassembled the bike.

The forks are the original Manitou Spyder R. The only thing I have changed was the elastomer to SOFT/blue - which suits me well.

The original Fox Vanilla shock is still in place, with a slightly increasing leak of oil as the years go by.

The original STX chainset, which appeared to made of plastic or marshmallow, has been replaced by a TA Zephyr triple. ( A bit of an upgrade there! )
