If big wheels, big rides, big races and big adventures are your thing?

If big wheels, big rides, big races and big adventures are your thing, the Tallboy LT is your big ticket.

Our 135mm VPP™ 29er hauls riders through such brutal events as the Downieville Classic, Andes Pacifico and Trans Provence.

29" wheels are a noticeable advantage on long rides and multi-day races.  They keep up momentum, smooth out terrain and give an impression of more suspension than the travel suggests.

Still available in different color options for aluminum, the Tallboy LT is like a Bavarian sports tourer for the offroad World.

Interested in other All Mountain/Trail options?  The Bronson and 5010 are worthy 27.5" wheeled candidates.

Tech Support

Can I mount a chainguide to my bike?

Yes, this bike is equipped with ISCG-05 tabs for easy chainguide mounting.  Most chainguides on the market that are made for this standard should work.

Can I use a dropper post on this bike?

Yes, this frame is equipped for internally routed dropper posts like the Reverb Stealth, KS Lev Integra, or X Fusion HiLo SL Strate. 

It looks like the lower link is off center in my frame- is everything ok?

Yes- this is correct. With our newer pivot system, the pivot axle draws the link over to one side in order to properly preload the bearings. This offset is accounted for in the frame design so everything ends up nice and straight in the end.

Should I grease the headset cups when I install them?

Yes, we recommend this. Do not use the Carbon Assembly Compound on the headset, as it will make it more difficult to remove from the frame.

What fork sizes are recommended?

The Tallboy LT is designed for a 130-150mm fork. We spec 140mm, which we feel balances the bike the best.

What is the torque spec for the front derailleur?

Torque the front derailleur to 45 in/lbs.

What is the torque spec for the seat collar?

We don't provide a torque spec for the seatpost, because it really depends on what seatpost you are using. Some seatposts are slippery, and require more torque to stay put, and others are very thin- and can be crushed by overzealous tightening. Some are both slippery and thin... Make sure you use the Carbon Assembly Compound included with your carbon frame, and use some common sense.

You will not damage your frame by overtightening the seat collar, assuming you have a 30.9mm seatpost in it.

What kind of front derailleur do I need?

This bike uses a 34.9mm Bottom Swing (high clamp), Top Pull front derailleur.

What kind of headset does this bike use?

We use a headset generally referred to as "mixed tapered". This is a 44mm internal upper cup, with an external 49mm lower cup. The SHIS name is ZS44/28.6 EC49/40.

What kind of rear brake adaptor do I need?

This frame uses a standard IS rear brake mount. Just pick your rotor size and order the correct adaptor to go from IS to post mount (all modern brakes).

What q-factor should I use for the cranks?

On any crank with optional Q-factor, choose the wider version.  166 for Sram XX, or 168 for XX1.  For Shimano doubles, we recommend the M980.  

What size bottom bracket shell does this bike use?

We use a standard 73mm threaded BB. Nearly any crank on the market (besides BB30 cranks) will fit.

What size rear hub do I need?

This bike uses a 142x12 through-axle rear hub, and includes a DT RWS axle.

What size seat collar do I need?

We spec a 34.9mm seat collar on this bike. Many aftermarket manufacturers will list this as a 35.0mm collar, but it is the same size. 

What size seat collar do I need?

Bikes with a 30.9mm seatpost require a 34.9mm seat collar. 

What size seatpost do I need?

We use a 30.9mm seatpost. Always ensure it is inserted into the frame a minimum of 100mm (4").

What size shock does it use?

This bike uses a 200x51mm shock with 22x8mm eyelet hardware (21.8mm x 8mm for SRAM). Please do not use any other shock size or modify with eccentric shock bushings- this can cause damage or clearance issues with the frame.

Why does this frame use a standard thread-in bottom bracket, when many of your competitors use press-in style (BB30, Pressfit 30, BB90, BB92, BB86)

It is true that there are some slight weight savings available with the various pressfit bb designs (exact weight savings obviously vary depending on system, frame manufacturing techniques, and crank model), but we don't feel this small savings make up for the inconveniences. We are still able to make a frame that is lighter than most of our competitors, while still using a heavier bb system. There are a number of disadvantages that exist with press fit systems:

1) Special installation and removal tools are required for these parts, including a headset press. This is not convenient for most home mechanics, and they are quite expensive. Traditional external BB's can be installed or removed with a simple $10 hand tool.

2) "Permanently installed cups". Shimano doesn't recommend removing and re-installing their press in bb cups (as they may become damaged), so moving parts from bike to bike is no longer an option. http://techdocs.shimano.com/media/techdocs/content/cycle/SI/SI_0053A_001...

3) Creaking or shifting bb's can be common with these systems. Since the bearing is pressed into a cup, which is then pressed into the frame- it can be hard to get all of the press fits snug- without being too tight on the bearing or too loose in the frame.

4) Reasonable tube sizes. One of the most commonly claimed advantages of a larger bb shell is the larger diameter downtube that goes with it. This may be an advantage on road bikes, where tubes can be incredibly thin and large for optimal stiffness. On a mountain bike, this area of the frame sees a lot of abuse from rocks and crashing, and needs to have a certain amount of wall thickness to survive actual use. Using what we consider a "safe" wall thickness and carbon layup, and a fairly typical tube diameter, we get an exceedingly stiff, light, durable product. If we used a larger downtube, we would either have a heavier frame (same wall thickness but larger diameter), or a less durable product (thinner walls and larger diameter).

5) Chain clearance. Take a look at some of our competitors frames with press in bb shells. The down tube comes so close to the chainrings that many frames have chainsuck guards on the downtube! In our mind, the chain should be able to fall off on a mountain bike and not get jammed between your crank and thin-walled carbon downtube.

6) Backwards compatibility: Many of our customers purchase a frame and build it up with their choice of parts, or parts from an old bike. By using a standard bb, we are compatible with everything without requiring confusing adaptors.

7) Chainguide compatibility: While it may seem strange to talk about putting chainguides on a short travel bike, it is becoming more common now with 10 speed drivetrains. Thread in bb's mean the frame is compatible with bb mount chainguides. We like versatility....
