Fixed Innovations axle
Our axles are made to our design by Bullseye Cycle Corp. They're
turned from centerless-ground 12mm 7075 aluminum rod stock, and are
identical to standard Bullseye axles but for the eccentric ends. We've
never seen one fail; but more significantly, Bullseye hasn't either,
and they've been making them for 25 years.
Our axles are available either as an upgrade for Bullseye hubs
you already own or with Bullseye hubs purchased from us.
We stock axles and axle kits in 130 and 135mm lengths. Other lengths
are available but may take longer to get. MAILME(Tell us) what you need
and we'll give you an estimate of when it'll be available.
We offer a custom-width double-sided version of the hub that
Bullseye has been making since the early '70s. Flanges are identical
to those on "normal" Bullseye hubs, so you can run a freewheel in
place of your fixed cog when you want -- assuming the hub is spaced to
Flange spacing on our Bullseye hubs is 52mm. This lines
both cogs up perfectly with most small chainrings; if you want to use
one cog with the big ring and the other with the small you'll want to
respace the hub slightly so that each cog is about 4mm inboard of the
chainring it goes with.
Bullseye hubs are available in drillings from 28-48, and with axle
lengths from 120 to 145, all at the same price. Flanges come in any of
seven colors (blue, red, purple, lavender, green, black and silver;
black and silver only for 40 and 48 holes; see Bullseye's color page for
details), again at no extra cost. (Center sections are silver only.)
We stock only silver hubs, but are happy to order other colors.
Bullseye axles take either quick releases or bolts. Bolts are
included. If you prefer a quick release, we carry Salsa's Flip-offs
or you can use any QR you already have.
Notes: The lack of a lockring means that, in theory at
least, your fixed cog may unscrew -- during hard backpedaling, for
instance. Anecdotal evidence suggests that this is not a problem in
practice, and particularly not with gears above 65" or so, but you
should be aware of it. Don't even think of using one of these hubs on
a bike without two working brakes -- not that that's a good idea
under any circumstances! And use Loctite rather than antisieze when
installing the cogs.
Phil Wood hubs
Phil's double-sided-with-lockrings track hubs, while expensive,
are probably the ultimate hub for a dedicated fixed gear wheel.
The lockrings ensure that the cogs won't come unscrewed, even with
very low gears. Flange spacing is 58mm, which places the cogs for an
almost-perfect chainline with either chainring (assuming your
chainrings are centered about 43mm from the frame's centerline. This
is normal for a road bike, but exceptions abound.)
Phil hubs are Available with bolt-on or hollow quick-release-ready
axles, in 120, 126, 130 or 135mm lengths. 126-135mm cost
more. Drilling for 28, 32 or 36 holes is standard; other drillings are
available but cost more. QRs are not included with the hollow Phil
axles, but we carry Salsa's Flip-offs or you can use any QR you
Phil offers a single-sided version of this hub at a slightly lower
price, and one with one side threaded for a single-speed freewheel.
