Is this a first gen Stumpjumper?
 

From a friend’s basement.

I don’t see a Tim Neeman sticker, or any sticker.

he admits to swapping out the bars back in the day.

it has the flat plate fork crown. Might be 2nd year

VERY first would have been shipped with TA cranks and "bullmoose" stem / bar combo.

I have a Nitto bullmose available

fork shows it is very early for sure

Presta valves? QR front axle? No Biopace? Guessing it's been considerably modded but the frame and some components seem period-adjacent at the least.

Agree that fork makes it an early model. Exage group was not out until 1987. Guessing that was likely swapped in at some point?

Here's a first gen 81, they had different graphics/livery, no biplane.

The biplane was used until 86.

Neenan sticker very hit and miss.

Are the Ground Control tires in decent shape?

As others have pointed out, the components are all later era. My Stumpy (purchased July 23, 1982) frame has only a single set of water bottle bosses and is welded, not lugged/brazed.

Nope! :)

No, the first ones had a four-bolt BMX stem. Bullmoose came later.

Looks like an 83'.

My friend said it came with the bullnose, but he removed it because his arms weren’t long enough so that’s why he swapped out the stem and handlebars.
