Fixed/free rear wheel in 130mm with a wide rim?

[DismalScientist]

Bikes direct sells a wide tire fixie with an Alex G6000 rim. Couldn’t find them selling the wheels separately on their website (nor on bikeisland.com). Looks like it has 120mm spacing, but you could always add spacers to the axle, if long enough.

Anyone know of a source for a pre-built fixed gear rear wheel or wheelset with a 130mm wide rear hub and a rim wide enough to mount a 700x38mm tire? Or is that something I’d have to have built?

To answer your question, no. However, in the mountain bike world, we goofballs figured out a way to make regular disc hubs into fixie hubs by essentially drilling six bolt holes into a singlespeed cog to match the disc rotor mounts. Companies (Boone, Tomicog, etc.) ran with the idea, but the only one that I know that still does it is VeloSolo:

What this means is you can find any 130mm hub with a 6-bolt disc rotor mount system, pop the disc fixie cog onto it, and spin your life away. On the flipped freehub side you can put spacers and a single cog for freewheelin’ fun.

Chainline is a little wonky, but not enough to derail even on rocky trails. I used to lead ridiculous “scorching” (fixie mountain bike) rides through some local bumpy trails:

Thanks folks. I did a little more hunting about and I think what I’m looking for is a wheel built from Surly’s 130mm flip-flop rear road hub, or the equivalent. It has a 47.5 chainline. Unless I can find a used one Ebay, or I may have to have one built.

I actually have a 120mm wheelset I bought from Harris Cyclery 12 years ago, still in good condition. They were a decent match for the 80s Trek road frame I paired them with, using 5mm axle spacers. But now I have a newer frame with clearance for bigger tires, and I’m fairly certain a 42-43 chainline of that old wheelset isn’t going to work with it. The chainstays on the new bike are pretty wide so as to handle the bigger rubber, and either the chainring or the crank is going to hit the chainstay when lined up with the rear sprocket. Hence the need for 47.5 chainline. I need to measure to be sure, though.

Quality Wheels makes a wheel intended for converting a Surly Crosscheck to SS/fixed using an Alex DA22 rim laced to a 32h 130mm Surly Ultra New Single Fixed Flip Flop hub. It’s QBP PN WE4604, if you go to a QBP dealer, just ask them to order this PN. Should be about $200.

Thanks very much. I’m not sure the rim is wide enough for a 700×38 tire but it’s good to know about it. I came across another option from ProWheelBuilder, about $170, which would pair that Surly hub with a Mavic 319 rim (would match my existing front rim).

The Alex rim will be fine running a 38mm tire. Though the Mavic [#]19 rims will be good out to a 45mm or 47mm tire, I believe.
