Marin East Peak

[elspedo]

Evening,

Yesterday I put a post in the wanted section for a cheap rolling project, I was after a cheap Kona or Marin and oddly as I went back to the main board a Marin East Peak appeared in the ebay ads with only 15 minutes to go and at only £36 so I put a cheeky little last minute bid in and this morning made the 4 hour round trip to pick her up:



Stripped down this afternoon and cleaned it up, frame has a couple of marks where it looks like something has rubbed against it and taken paint off and looks as though some has sprayed a can of black pant near the rear of the bike but this comes off with a light rub, apart from that is perfect.

The gears are all over the place, front shifter won't go up into 3rd position and derailleur won't even pull high enough up if the shifter did work, rear derailleur jumps from 1-3rd no matter what I do.

With all the problems with gearing my plans are to swap it out for a 1x10, pop a disk brake on the back (how hard is that with this frame?), swap the front fork for something a bit nicer and swap the pedals to SPDs. Trying to do it all on the cheap so maybe a slow burner.

Hi elspedo, should make a nice little project, I've just built a '97' rift zone frame (£23 on the bay)into an xc rat bike with all my leftover bits! Took it for a ride this arvo, amazed how good the ride was (cheated with a fox rp23 shock though) : ) as for the disc brake you may need to swap the swing arm out for a later one.

Make sure the cranks are on properly and that it has the right size bb fitted, that could account for the shifting problem. As far as a disc mount goes, I'm not sure an adapter would fit, but you can often pick up similar vintage swing arms on eBay with disc mounts as per bogs suggestion.

Re:

I have had a couple of Marins with this frame design and I have to say they have stood the test of time well and still ride very well.

Ye I think the problem maybe with the BB as it's measuring ~54mm fem centre of tube to middle ring, not a big problem as was planning to change it when I went to a single ring on the front to get correct chain line anyway.

Forcefully removed the rear suspension last night, the lugs attaching it to the frame at the front did not want to come out! Taking the frame in to work today to give it a proper look over and fairly tempted to sand it down while it's like this and do a proper job of rebuilding it.

Later rear end had a disc mount of sorts that you could at least mount something to but yours is the earlier non mount version. Check for cracks as they all did and were often replaced under warranty with the later design.

Re:

No cracks in the swing arm i'm afraid, may just stick with the avids already on there as they seem to stop on a penny anyway.

Got it into work the other day and spur of the moment thing decided to sand the frame down on my lunch break so currently working that back up through the sandpaper grades then give it a good polish, aiming to get the frame matching the swing arm, it may look terrible but I haven't lost too much money in the process.

Going to be purchasing the groupset next week probably as should have frame all sorted by then, anyone got any recommendations for running 1x10? I was looking at the SRAM or race face stuff on ebay seems to go for an ok price, if anyone has anything lying around they don't want him me up.

Looking for basically the whole groupset 10 speed shifter, crankset, chain, cassette and 68mm BB as i'm pretty sure the one on will have the chainline out?
