I am just about to go from my MED 5.5 to a MED Tracer VP...hopefully I can fit It correctly. I run a 80mm stem with 20mm of spacer.
I usually only run about 15mm of spacer, with 5mm on top. I test rode a Tracer VP when they first came out, It did feel more compact, but I didn't notice any issue with reach or leg extension.
I am about 5'11", I'll post some pics as soon as I build It up. The build will be with a new Rock Shox Revelation 150mm fork, I will keep the rear set at 150mm as well, with an 80mm, 0 rise stem, and 27.5 inch bars.
