This is one of the things I've been up to for the past year or so - working on graphics for the Overmountain line, specifically the Trigger 27.5 and Jekyll 27.5. My favorites are the Jekyll Carbon Team and the Trigger Carbon Team and 2. I've got a soft spot for the Triggers especially.
It gives me warm fuzzies to read an article and look through the photos of pro riders ripping around on 'my' bikes. Like, say, this article on exciting new rider Marco.
I do all I can and it's rewarding to see the finished product.
