BRAIN upgrade for Stumpy?

Lee, in the 300+ hours I’ve been crafting a pump track this summer i’ve been doing a thought experiment on the “Swiss Army Knife” bike i want to buy in the spring.

I’m pretty much concrete on a Stumpy 29er but limited funds will probably = entry spec bike.

During the summer I tested an Epic and the Brain made me very, VERY happy (and shockingly fast). My question is at a later date when i’ve saved my “upgrade” pennies can one add a Brain to a lesser model Stumpy?

Any help would be greatly appreciated.


Hey Alastair,

The Stumpy 29 sure is a sweet ride. My Stumpy 29 S-EVO is super freaking rad.

Oh yes, the BRAIN technology is sweet. It gives you a bike that’s stiff for pedaling and pumping yet plush in the bumps. Check out Brains for braaap.

If you buy a “lower-end” 2012 Stumpy 29, you can indeed upgrade it to a BRAIN shock. You’ll need the shock and the seat stay.

My instincts say this might cost about $700. (Do not quote me on that.) My instincts also say this is not a great idea. Get whichever Stumpy you can afford then wring it out. Don’t mess with changing shocks.

Any stock Stumpy 29 is going to rip.

My Stumpy has a stock 2012 FOX FLOAT RP23 Adaptive Logic Boost Valve shock and a special FOX 34 FLOAT 29 140 FIT RLC fork with 2013 air spring. The suspension on this bike rips the pump track and rallies rock gardens.

Have I mentioned my bike is rad?


Know more. Have more fun!
