Mason Manufactory.
Functional bicycles for discerning people;
also racks and whatnot
The Mason Mighty was designed from the ground up to be a wholly different bicycle. By borrowing design cues from the best parts of several different genres of cycling we hope to have created a bicycle with illimitable potential; hence the name.
Today’s cyclist is apt to have several machines in his or her arsenal: a race bike, a grocery-getter or townie, and maybe something for light- or even heavily-loaded touring. The Mighty cannot do all these things perfectly, but it can do them all comfortably. It is designed to carry a load - both front and rear - with a slight bias towards the front so that the rider can see her cargo. The extra room in the fork and rear triangle allow for large tires to smooth out rough terrain, and fenders to keep everything dry. If you strip all these “accessories” off, you are left with an incredibly light, high-quality, brand-name (Reynolds 631 or 520) steel frameset perfect for whipping around the city or countryside in a genteel and fashionable manner. If the discerning cyclist needs more than one bicycle, he might as well own two of these.

- disc and canti compatible
- plenty of clearance for fenders and wide tires
- low bottom bracket height for increased stability
- Three water bottle braze-ons make camels jealous

Mason Mighty 631 frameset (frame and fork only)
$779.99
Same as above, but made out of Reynolds 631 air hardened tubing, and with an incredibly tasteful two-tone finish
Custom/Special Edition Racks
$209.99
Hand cut, mitered, and brazed from stainless steel tubing. Do you like reclaimed wood and bright colors? If you can draw it, we can build it. Also check back for special edition one-off racks.
Dia-Compe Silver bar-end shifters
$64.99
My favorite bar-end shifter for simplicity's sake. Smooth micro-ratcheting action feels like the old Suntour powershifters, and works with every combination of derailleur out there (update: except for SRAM rear derailleurs…).
Tektro RL520 long pull levers
$20.99
Great for both linear pull AND disc brakes: that's why we chose them.
Tektro Lyra disc brakes
(set includes front, rear, and 160mm rotors)
$74.99
Tektro's new disc brakes were designed for use on cyclocross bikes, however we find them exceptionally friendly for road and touring use. We currently don't stock the 140mm rotor - our sets come with 160mm rotors for both the front and rear. When you're riding with a heavy load, you'll thank us. (we also stock replacement pads for these. If you need them, ask.)
Classic alloy drop bars
$14.99
Classic drop bars with smooth lines and a smoother ride. Works great with Dia-Compe bar-ends and the RL520 levers (pictured).
Alloy city bar
$14.99
Super comfy city bars. ø = 22.2mm (Careful, bar ends don't fit this spec; you must use mountain bike specs for shifters and brakes)
Steel cruiser bar
$10.99
Economical steel sweptback upright handle bars that work like a time machine. With a little work this just fit bar-end shifters - ID is 19.4mm.
Long rise dirt drop quill stem
$14.99
Used frequently in conjuction with mustache bars. extension = 60mm; rise = 30º, length 180mm
Short rise quill stem
$14.99
Used frequently on Dutch bikes, this stem is extremely comfortable for an upright seating position that brings the bars to you. extension = 39mm; rise = 30º
threadless quill stem adapter
$10.99
For those who long for the convenient adjustability of a quill, but don't want to get rid of their fancy threadless stem.

Double-wide smooth fenders
$22.99

Stainless Steel Rack Tabs
$16.99
For the do-it-yourselfer. If you know the ways of the torch, we are happy to sell you some tabs so you can bend your own and braze it as you see fit.
We reccomend using nickel-silver for this. Tabs are waterjet cut, and then tumbled lightly for finishing.
If you want a mirror finish, polish them yourself.
