Hello,
Been brought a rather old Marin DH FRS/B17? to have a look at the swing arm bearing.
Are spares still available? Any other things to look at on these?
Thanks in advance!
They will be standard bearing sizes.
Just extract and read the code on them.

Ta, got a few bearing contacts through my other hobby, though those are normally large imperial bearings...
Have a look at the downtube-headtube join (underneath), loads of them cracked there
Got the cad diagram (somewhere) for the rear disc adapter (& some of the bolt inserts), if it's not already converted
Most of them went when the main pivot removed it's self from the downtube....Mine included 🙂
Mine broke here but Marin gave me a new quad link frame 😆
Bearings had 'KP6A' written on them & ATB sales used to send them out FOC

Had a friend with one of these. It had had that many replacement front and rear ends we called it triggers broom....
Check for cracks.....

Me too (a Mount vision not a b17) & then a new backend at least once or maybe twice, but I did enjoy my time with them (ended up sell it on here to some one who needed a rear end)
Hnggggggggggg you're bringing back memories of the single worst bike I've ever ridden (I had a red shoreline trail) - that retarded my riding by a number of years.
Tbf the shoreline trail was a cheap & cheerful bike, with components to match (with BSO shocks), not even a rear disc mount IIRC. Produced no doubt to make use of the old but workable jigs, when they'd moved onto hydro formed frames for there main models, so was never going to set the world alight.
Had a B17 with Tomac Magura HC33's on it! Memories!! 😀

It was a bouncy, high, flexy POS - it didn't even just fail to set the world alight - it was a ****ing killer on wheels. I remember riding a stiffee with Pikes for the first time and thinking "**** me, this is comfortable/safe feeling".
😀
If that;'s the worst bike you've ever ridden then you've done pretty well 😀
Things to watch out for, as above, are cracks. cracks, cracks and more cracks.
The best thing abou these frames was the cast iron warranty!
I bought a SH Quake frame, it broke, I got given a DH FRS, that broke, new rear end, broke the front end, got another one, that broke, broke the swingarm twice, got whatever the blue one was at the time (retaining the orange rear end), swingarm broke, got given an pearl white attack trail, which then had several new parts. Along the way there were also a number of new shocks thrown into the mix!
They were high, but no worse than most contemporaries, and they were pretty much ground breaking at the time - a mass market 6" travel bike for around a grand? Mental.
