lamere cycles, Kiroshiro wheels, hardtail, carbon wheels

We proudly offer the world's lightest and most-affordable carbon fat racing bikes built one at a time here in Minneapolis, exactly how our customers around the world want them, and always at a price about 25% less than the bike shop.


A true carbon fat bike pioneer, we have tweaked the frame design slightly over time to make it light, agile, fast and comfortable. Our steep 70.5 HT angle makes for a quick and responsive handling bike, while the slightly longer 467mm chainstays give you great stand-up-and-hammer traction on the hills, more stable high handling, and better bump absorption.

We now offer 4 different fat bike frames to choose from, and soon we'll have a fifth in stock in our warehouse! Two frame designs can be had in either 177mm or 197mm rear-end axle spacing, the others are 197mm only. All of which can fit 5" tires and big 27.5 fat wheels.

Here are some sample kits below. But call us directly to customize exactly what you want!

     Sram XX1 with LaMere Carbon Wheelset: 21.8lbs

     Sram XO1 with LaMere Carbon Wheelset: 22.5lbs
     Sram GX 11spd with LaMere Carbon Wheelset: 23.25lbs
     Shimano XTR 11spd with LaMere Carbon Wheelset: 22lbs
     Shimano XT 11spd with LaMere Carbon Wheelset: 22.5lbs


* All the above weights are with wimpy HuskerDu tires, so add a pound to each build weight with real winter tread.

Add HED Big Deal or BFD wheels with new carbon Brickhouse hubs to any build for an additional $500.
