Bike Manufacturer Identification

Hi All! I've just joined the forum and have just started learning bike repair. I've purchased an MTB that had been sitting in a barn for some time and there is no manufacturers name on the bike frame, just a symbol on the head tube. Anyone know who the maker might be? I'm guessing someone like REI? The frame appears to be a chrome moly with a clear coat over it and has Shimano Alivio components (just a captiol A on the parts).

Thanks for any info you may have!!
Mark

previous owner may have added the head badge logo themselves.

If you don't find out the manufacturer it's not that important. The components would have come on many other bikes, and the frame could well have been identical to other brands as well.

It is strange how the rear brake cable, front and rear derailleur cable all are ran across the top tube.

That's been the de facto arrangement on hardtail Mtbs since 1993 or so.

Oops, just glanced at girlfriend's 95 trek 820 with under bb shift canle routing. Maybe more like 96 or so.

My '92 Trek 7000 MTB had the same over-the-toptube cable routing for both brake cables and both shift cables. The front derailleur cable ran down the seat tube and anchored to a bolt just above the bb shell and the housing stopped at the bottom pull fd with a adapter to let it push down on the operating arm. The rear derailleur housing routed down the drive side chainstay to the final loop to the rd itself. A bit awkward but it all worked.

Some do and some don't. Specialized runs the shifter cables along the down tube and has for years.

2003 Specialized



2011 Specialized



But other companies do it differently

1998 Moots



1997 Trek



1998 Nashbar (probably Kinesis)

Yeah, the 95 trek 950 had cables running up top too. 800 series must've been too low end to enjoy mud free derailer cables

Specialized designers just don't ride mud, apparently

Now back to the OP. The welds look too thick for CrMo. Have you tried to magnet test the frame?

If it is CrMo there shouldn't be many steel bikes with such thick stays. Marin had constant diameter steel stays but their head tubes were externally butted IIRC.

As for the REI guess I don't remember that head badge on their Novara line. As another poster said that sticker may not be original. And I don't have encyclopedic REI bike knowledge...

Yep, you're right! It's not CrMo, just checked it with a magnet, no stick! Thanks for the feedback all! Guess it doesn't really matter. It would have been nice to know when I go to sell it. Most people looking for a $100 bike won't care about the frame type, just that it looks and runs well.

Sorry, one more question, and I can post it elsewhere if needed, but what model Shimano derailleurs have a capital A on them? Alivio, Acera? The bike, I'm guessing is from the early 90's.

Thanks!
Mark

I've always guessed that the ones with the A were part of all 3 A_____ groups - Altus, Acera, Alivio.

I'm gonna see if I can get to the bottom of that, since I have some free time.

I have one that's RD-MC16.

It's shown here as part of Alivio, but that doesn't mean it wasn't also in the other A-groups.

A-ha, just subbing in the altus and acera at that site returns pages that show that they had different RDs, with their group names spelled out for the 1997 model year.
