1992 (?) S-Works M2

Argh

Retro Newbie
First, I want to say part of my research on this bike was greatly helped by multiple posts and resources on this page. Thanks!

So, I got a screamin' deal on this S-Works M2. The paint is in bad shape, and there are a few small spots of corrosion here and there on chromed parts. But hubs, wheels, bottom bracket, shifters, derailleurs, brakes are really excellent. It's been sitting a long time, and the fork needs an overhaul.

I believe it started life as a '92 S-Works M2 frame and Future Shock, which were then built with a full XT group. The parts don't match _any_ M2 model configuration I can find. The paint and graphics match the '92 S-Works M2 base model, which they just called "S-Works M2."

The serial number (inside of left rear dropout) starts with 92T. Does this indicate year? I've seen it on other S-Works MTBs.

The wheelset is a pair of WHEELSMITH, 32° Sun Chinook built onto XT hubs (FH-M732 and H-M730.) I was working in bike shops in the 80s and early 90s, and Wheelsmith were about the best pre-built wheels you could get.

3x7, XT front and rear.

The SH/BL are XT Rapidfire 2-finger, ST-M095, which I believe were new in '92.

The crank is XT. Which is one of the things that makes me think frame/group build. Because if fading memory serves, the XT crank was cast, while the Specialized cranks (made by Suntour and spec'd on virtually all the M2 bikes except the Micro-Drive ones) were cold forged, and lighter. So if someone was just upgrading a bike, it would be silly to remove a Specialized crank to put on an XT. 🤷‍♂️

The BB is an XT sealed unit. Headset is XT. "Low profile" XT cantilevers, which were about the best thing going pre V-brakes. (Intentionally ignoring U-brakes and roller cams here, which were stronger but came with their own sets of "issues.")

The stem is a middle-of-the-road cro-moly unit, similar to what was spec'd on M2s. Crappy "boing-boing" seatpost; I think this was added when the original owner got a lot older. Possibly at the same time he put on the street tires, which weren't even ridden enough to wear off the mold seam.

There may be a crack starting at the edge of the downtube-headtube weld. I need to clean it a lot better to be sure. It wouldn't be surprising given the extreme rigidity of the M2 tubing.

Anyway, super fun, and even if the frame is unusable, the parts are worth considerably more than I paid. (But an M2 frame would be pretty dang cool, doncha know?)

What's that? How much? Heh. I bought this bike and a new, still-in-the-box ukelele for $57. I am not making this up.

Looking at the parts this M2 was indeed a good deal! Even more so if the frame is not cracked!

I have the same one in a bit smaller size. I think they are from 93…at least that’s when I remember seeing them on the Specialized catalogue in black colour. Might be wrong…

We have recently been discussing another M2 here and have provided some of the documentation around duralcan. Have a look!
 
Wait, there’s an unanswered question!
Yes, from 1990 to 2000 the first 2 digits of the SN indicated year on aluminum and M2 Stumpjumpers, Ground Controls and S-Works. This seems to be manufacturing year and not model year, as there are some discrepancies around “crossover models” and my 1991 (as well as several others) is stamped 90. Most of the time it is accurate though — but make sure to check the catalogs.

Head over to my M2 thread for the nerd stuff! ✌️
