    Ti 29+?

    I am starting to think of having a titanium custom 29+ built but I want the option to run 5" tires. Is there anybody that has something like that or any feedback you can give me?

    *I also want to run a Rohloff and Gates but I need to prioritize so I may add it after.

    5" tires means a wide Q factor on the cranks. The belt will make it a little wider still. The rear will also have to be wide and I don't know if they make a Rohloff that wide yet with the pulley taken into account.
    Full rigid SS, Hardtail SS, Hardtail Geared, Full Suspension Geared.

    170mm SPEEDHUB for Fatbikes (update): www.rohloff.de

    You're really talking a custom fatbike frame with an asymmetric build to give sufficient clearance for 5" tire. Expect you'll need 190 Q-Factor cranks too.

    Some good points - I thought I could getaway with 170mm for a 5" but I guess not. If I'm running 29+ (3") I don't know if there is much of a point to run another wheel size smaller than 5".

    I know the REEBdonkadonk will run fatties and 29+, not Ti, but they might build you a Ti version.

    I don't know what part of the country you are in, but I had Ti Cycles in Portland Or build my wife a custom adventure touring complete bike fairly reasonably It is gorgeous. Already been to Italy and Idaho Hot Springs this season. They added S&S couplers to hers and to my Ti Fargo. They seem to have a lot more capabilities than is immediately obvious on their website. I am pretty sure they could build your 29er+. Talk to Eric or Dave.

    Add Sean Chaney at Vertigo to your list. He likes a challenge (and makes fat bikes way too much).

    I think that a 170mm bike that can fit 5" tires is a perfect frame to have custom built. I don't think there are any clearance issues with 5" tires and the 170mm Rohloff hub. But since that has not been available and is a niche market anyway 170mm bikes are not designed to be able to fit 5" tires. When Salsa designed their Mukluk the biggest tire they could use on the back with a 1x11 drivetrain was a BFL on 82mm rims, so the clearance on the chainstays, seatstays, and seat tube are designed to clear that tire.

    I just bought a fat bike and i've always wanted a titanium frame. I didn't feel that I knew enough about exactly what I wanted to justify getting a custom frame, so I ended up with a Mukluk Ti. But I think that what you want would be worth going custom.

    29 x 3 tires are a little taller that 26 x 4.8 tires, so that will be a factor when you change back and forth. I think that it is small enough that it won't be a problem. I'm thinking about trying out 27.5 x 3 tires out on my fat bike when they come out.

    Just to add, I have a custom ti 29+ and I'm in the process of designing a custom ti fatbike so getting into all the details about geometry, hub and crank sizes. 29+ has a bigger rolling diameter which can have a bearing in terms of BB drop - suggest you check standover clearance on the likes of a Krampus when sizing. For 5" tire and Rohloff you'll want a 170mm-width asymmetric frame - 190mm symmetric appears to be the trend.

    My Fargo is a 2013. I got it as a close-out last January. I was concerned about the couplers, but honestly, I cannot tell any difference in the handling. The cost was $1100 because of the oversize down tube. Eric did a great job of handling the oval shape at the bottom of the downtube. I decided because we don't have a Salsa dealer, and the availability of the 2014 Fargo Ti was delayed, decided to have Ti Cycles build a Fargo style frame to my wife's size, which came out to be between a small and XS. The bike is a beauty, and it covered many Km in Italy and the PNW this summer. It took about 2 1/2 months to turn things around. It sits in our livingroom as an artwork. Her frame and fork was around $2400. Her frame was made in Asia. TiCycles hand makes frames in Portland but have the capability to send CAD drawings to Asia to have more of a "production frame" available, even though it is custom, thus saving about a grand. The Ticycles titanium fork is a great alternative to a carbon fork, for about the same money and won't fail catastrophically as a carbon fork is capable of. The top pic is her bike, the bottom dusty one is my Fargo. I am envious of her ti bars and fork, but I love those woodchipper handlebars.

    thats pretty darn cool -i also have a 2013 and always figured that coupler would be impossible
    agree on the woodchoppers- wish they made a carbon version
    i think if the did they should take a bit off the ends and make the top longer resulting in the same overall width but a wider spread of the hands

    Spent some time speaking to some builders over the past few days and have gotten some good ideas. It seems to be a straight forward build but I still want to nail down some of the details.

    I may give Steve Potts a call and see if he could do something as I've always wanted a Potts Ti but the cost may be prohibitive. There are tons of great builders out there so it is tough to narrow it down.
