Searching through kijij to find something cheap to turn into a single speed, I came across this Brodie Catalyst in the next town. Wife preggers, bike's gotta go, yadda yadda yadda. Met the guy, hummed and hawed. Price kept going down with every haw. ;) Picked it up for way less than I had figured.


Finally finished, and I don't want to know what I spent. I went for (as my buddy is fond of saying) black on black with black accents.

The modern frame is V brake only. Had to make my own hanger. We're not busy at work at the moment....


Spent way to much money for what it is, but it's an evil looking little thing, and fun to ride.


Swapped out brakes/levers for Avid Tri-Align II canti/Avid Ultimate Black-Ops levers combo and Ritchey Pro bars. Avid listed Tri-Align II brakes as coming in black, but in all my years, have never seen any. Found a set of NOS red and a set of NOS blue ones, stripped the anodizing off them, and had then custom anodized flat black to match the Black-Ops levers.

Like it a lot , very similar visually to my explosif . Ie small and mostly black :LOL:

You've just got to love the DX pedal , had to stop using the real ones years ago due to the high cost and the damage :(

Thats a great looking bike. Think I'd be after a shorter stem but the rest looks spot on! Oh and the hangar looks amazing.
