That's cool that you like your new Stumpy Evo Carbon. My '88 Stumpy Comp makes a great commuter; my '91 Team Stumpy makes a great gravel bike. I rode the Stumpy Comp 28 miles yesterday because it has fenders. The MUP still had some snow and it was in pretty bad shape. The 26 x 2.0 continental winter contact tires handled the road conditions well and the fenders kept me clean:

By the way, given how badly your '84 Stumpy is performing, you could pass it on to me since I like repurposing badly performing old bikes,
