    bob trailer and fat tires

    Bob trailer makes a trailer fork for 29er wheels that replaces the trailer fork for 26ers Ibex trailers, which i have. As Bob Trailers has merged with a stroller company, customer service is painfully slow to get through (30 minutes on hold is beyond my wait threshold). Has anyone tried a 29er Bob Ibex trailer with a fat bike. I need to know if the fat tire 4 inch (pug) will fit in the 29er Ibex Trailer fork. TRAILER FORKS | BOBgear

    Thanks,
    urmb

    I ask them to design one to work with my 29ER Old Man mountain rack. The one that hooks up with old man skewer, I pretty much just got laughed at by BobYak. They will fall to the way side with their attitude.

    Radair, thx for the post, all my searches missed your thread. The top down picture of the rear tire in the trailer fork is what I needed to see Looks like the endomorph was rubbing, or close to it, on the trailer fork. Did you stay with the endomorph or use a narrower tire?

    You expected a company to design a custom part for your specific application and you think the fact they wouldn't is a sign they are out of touch???

    That was just an unrealistic expectation on your part.

    The photo is deceiving, as there is maybe 1/2" of clearance with the Endomorph if I remember correctly. Works well on a Pugs with 3.8" tires.

    It shows that they know they could MAYBE sell 100 of them, and the price required to make a profit would be more than you are willing to spend.

    Even if they did make it, someone would just send it to China, and they would reverse engineer it and make a cheaper knockoff. Then everyone would criticize BOB for being out of touch, and continue on with their daily lives.

    fatbike+thru axle+BOB

    We are currently testing BOB Trailers on fatbikes with thru-axles. We'll soon be producing 197x12 axles to match your BOB to your fatbike. We've comfortably fit 4.8 Big Fat Larrys on 100mm rims with a standard 29'er yoked BOB. However, 4.8 Lou's on the same rim do not fit, FYI.

    It can be done. Those enjoying their fatbikes with trailers will be giggling down the trail, not just laughing.

    Nah it was the Santana skewer they were worried about. It was meant for 165(? I believe) mm and not 170mm. While some people had it on some others were wary about pulling it with any sizable force on that thing.

    OT: I looked at my 29'er fork against my mukluk, and it looks like it would fit. However I use fenders for the winter and that would require customization

    Well here was Bruce's exploits from earlier in the year and he has just finished installing his new water heating log burner, so this is in use more than ever!

    coastrider: Sand Road Truckers...

    One of my other friends has also got a trailer and he loves it too. Stuarty is using his with the normal tyre but I don't think he goes on the soft sand carrying as much load as Bruce does.

    Would also like to set this up on the fatty, but not sure. I have 197mm rear spacing, so its probably a no-go? I have a huge need for a Bob trailer where I live....haul the kids, gear, ice fishing and gathering wood, so I need to make this happen some how. Thnx!

    Both of my Pugsleys use 135 mm spacing and standard quick release skewers. I use the stock QR that comes with the BoB. No thru axle required.

    Thanks, RadAir for the clarification on the type of axle the Pugs use. So we don't do solution for 5mm QR's just 12mm thru-axles. We do offer just our axle ends for those owners of Surly's that use their thru-axle system called "MDS". Our axle ends bolt directly into that stock axle. Pretty cool feature from Surly.

    Resurrecting an older thread. :-) What modifications, if any, are needed on the bob trailer to accommodate it's use on a fat tire bike equipped with the proper Robert Axle. Im specifically wanting to use my Bob trailer with a yet to be purchased 2016 Salsa Blackborow GX. If I have too I will lower my sights a bit and go with the Mukluk X7 but I'd really like to get the 5" tire bike.

    You'll need the 29er yoke, not the short yoke that came with early BoBs. These can be purchased for only $60 to convert an older trailer. The yoke is easily expanded by hand (and foot) to fit the axle spacing but the ends or dropouts will be flared out. They will need to be bent inward slightly to make them parallel so they fit in the BoB's bobbins. This takes a bit of effort but is not overly difficult with a big enough hammer.

    It's also worth mentioning that the guys at the Robert Axle Project have the best customer service imaginable. I am not affiliated with them at all, just a very satisfied customer.

    Thanks radair, just to be clear, does that go for both 4 and 5" bikes or just the 4" bike. I see that awhile ago Robertxle said that it will work with some 5" tires but not others. Im hoping to also gain some knowledge on the 5" tire bikes. I currently have the 28 plus equipped Bob trailer for my 29er.

    I haven't put a BOB yoke on a 5" tire in awhile. As RadAir re-posted above fit was very specific to each tire/rim combo. I am going to have to ask our customers here on MTBR to post up their experiences with tire fit. The yokes will need to be bent a little bit to fit the additional width of these 197mm hub spacing. The yokes are made from CroMoly though so a little bending is no big deal. Tire fit though, that's a whole 'nother can-o-worms.

    Thanks Robertaxle, So if I go with the 2016 Salsa Blackborow (5", 197 hub bike) and equip it with an axle from Robertaxle, then i can bend the yoke to fit the hub, and if the tires don't fit to my liking, I'll just swap the rear tire to a 4" tire for trips requiring the bob trailer and roll with 5s the rest of the time. I think it's a good plan. :-) Time will tell.

    Good thread! Needs to be put near the top now and then

    I have a BOB, and just got the 29er yoke for it to fit my townie bike. It's so great to have a trailer to do in-town chores, but I'm not sure a fat wheel on it would do me much good.

    That video of the guy collecting firewood was most excellent, I enjoyed the shet out of that, and the music was nice (instead of hearing some grungy-type music )

    I got ribbed by a guy at the lbs for hauling a trailer with my laundry in it, he said I looked like a homeless dude! Lol. It's all in fun. I think.

    Hi, radair!
    Hi Finche! I hope all is well in NorCal. Nothing wrong with being a homeless dude if you're riding a bike!

    I have put a lot of trips on my trailer this summer, hauling somewhere around 60+ gallons of diesel fuel, 3 gallons at a time. It works great.

    I just bent the yoke out to fit and clear the rear tire. I have not worried about the bob trailer tire not being fat. 29er yoke on the bob.
