Advice on modernising a 90s Marin

[xtaffa]

Both - j3 and mags

I could very well be wrong but I think the Marin forks I took out of the Eldridge grade
are 1 1/8 and so are the j3s. Not sure about the mags. Don’t think I’m going to be using either on that frame anyway

Ok, my '92 EG is 1" threaded

 

[Stanflashm4n]

Oh maybe they are 1’’ then…I haven’t measured was basing it on these

 

[xtaffa]

B#gger me, think you're right I'm wrong - I've never measured either and just assumed 1"... as I said at the top, probably me being thick as pigswill... and I was!

This is a 95 team Marin with 80mm Rockshox Reba and 50mm stem, surly sunrise bars and lucky enough to fit a 27.2mm dropper post on this too

Thanks again for all the suggestions. Im going with the 1x drivetrain, I bought one of the superstar 34t narrow wide chainrings . Now I’m looking at rear derailleurs , can anyone explain why the ‘long cage’ shimano M600 SGS is recommended for use with a smaller cassette than the ‘medium cage’ m6000 gs version? Reason I ask is that I’m thinking of going for a 10 speed 11-36 cassette and there’s a M6000 GS derailleur second hand on eBay that I thought would be ideal but on the shimano website it says max low sprocket 42t and min low sprocket 42t … does this matter if I’m going 11-36t? I’m finding it confusing as from what I understand long cage = bigger cassette but this is the other way round?

I’m guessing these forks have a bigger axle to crown measurement than the stock forks?Still rides nicely?

 

[Beeewu]

Yes rides great! I guess marins in 1995 would have had 65mm travel suspension, so only 15mm difference

The long-cage version is meant for a double chainring with a smaller cassette, which will have a larger chain slack to deal with than a 1x and 42T cassette that the short-cage is designed for.
