in Buy/Sell and Lost/Found

Probably a long shot but I'm looking for a 26 inch fat bike wheel (for a 4 inch tire) that has a 170x12mm thru axle. These are hard to find online unless you plan to build one yourself. It's for a 2015 Trek Farley 6.

You sure it's not 177x12 mm TA? The 170mm is usually QR.

If I'm not mistaken, the Farley uses a "closed convert" dropout that sorta acts like a TA, but the hub is actually a QR.

I think you need a regular old 170mm QR hub, but I'm not positive.

The rear axle acts like a quick release but it threads into the frame on the drive side. The distance between dropouts is 170mm, but I guess you'd need a bit longer for the threads so probably is 177x12. I have the same setup on my Fuel EX, except that rear axle is 142x12. From what I can find online, most wheels use a standard QR hub, or a TA for a 190mm hub. 

I'm 99% sure that you need a 170mm QR hub for that.

It just requires a longer QR skewer, not a wider hub.  I had a borrowed Superfly100 that used the same system on a regular 135mm QR hub.

Do you have the frame in hand?  I have a wheelset you can test fit.  The wheels are for sale too BTW...kinda skinny rims though.

There are kind of a lot of rear hub standards in fat bikes.

170mm QR or 177mm TA (just like 135mmQR/142mmTA on a regular MTB).

190mmQR or 197mm TA (7mm difference just like 135/142)

Thanks for the offer Nate. I do have the frame so I can track down a test wheel. I'll run it by a friend who works at Trek. He designs the darn things so I would think he should be able to tell me

The 2015 Farley 6 came stock with a 177x12mm rear hub.  However, the rear dropouts on the frame can be converted to 170mm QR, so I would make sure your dropouts are 12mm.

I thought 6 and 8 being same frame had same wheels. Maybe not.

IIRC, Framed sells the Minnesota wheels that match or are with their Minnesota bikes for not too much $.

Thanks all for the input. I'm new to the fat bike thing so still on the steep end of the learning curve. The Farley 6 comes with 177x12 dropouts but it can be converted to 170x10 quick release with some new dropout inserts. The conversion kit cost $60. I found a set of Bonty Jackalopes that will fit the frame.

I'm new too - have gone from renting at CamRock or up north to buying a used Farley. I've made and kept a bunch of notes.

I'm really pleased with the way the Jackalopes went to tubeless. In my case they had the Bontrager tires that perform considerably better tubeless. At least pre-snow. My homework for those should yours not have Trek's parts is you should have their stem but other 21 mm tape works fine for the conversion. I used more sealant than I do for regular MTB tires.

I wonder if that kit you bought is same as a spare der hanger??? Over the years I've bought those for my bikes.

I suggest the analog air gauges Trail This stocks. The 30 psi model works for regular and fat. I find I spend much less time getting pressure right if I start with the gauge.
