Bullit FAQs
What kind options do I have for dropouts?
Three options: 135x10mm quick release, 150x12mm through axle, and 150x12mm through axle floating brake. You can order them on our online store.
What size headset does the Bullit use?
The Bullit uses a 1.5" headtube. The frames are shipped with reducers so you can use any 1 1/8" headset/fork as well. There are also plenty of reducing headsets on the market which allow use of the larger bearings of the 1.5" system along with your 1 1/8 fork. Of course, to get the full benfit of 1.5, use a proper 1.5" steerer fork for a stiffer front end.
What size seatpost do I need?
The Bullit uses a 30.9mm seatpost. Make sure you always have it inserted a minimum of 4" (100mm).
What size seat collar does the Bullit use?
34.9mm (supplied with frame)
Can I use the floating brake with a 135x10mm quick release hub? How about a front derailleur?
Nope. Single ring only. Through axle only.
What fork is recommended for the Bullit?
in general, we designed it around the Rockshox Totem single crown fork. The travel (180mm), weight, and general feel are ideal for the majority of Bullit riders. 160mm forks are better for a quicker feel, and certainly better if you are going to do a lot of climbing. The 1.5" Lyric or 36 Van (both 160mm travel) would be excellent choices for all around riding. If you are going to be spending most of your time shuttling, a 200mm dual crown will work great.
What size shock does the Bullit use?
8.5" x 2.5" (216x 63mm)
The mounting hardware is 22mm wide with an 8mm through hole.
What is the advantage of the Floating Brake Kit?
With the sliding seat tube clamp, you can tune how you want the bike to behave under braking. Lower positioning will provide less anti-squat than moving it higher on the tube. We put a lot of work into designing a clean system- so that you never have to remove the floating link or brake caliper when removing the rear wheel, unlike some other designs.
What size bottom bracket do I need?
The Bullit uses a 73mm bb shell, so make sure you always get something compatible with that.
For either of the 150x12mm through axle options, you will want a 56-57.5mm chainline. Our favorite is the Truvativ Holzfeller Howitzer. Get the 73x56 (chainline) bb for this system. Other options are the Raceface Diabolus cranks. You will need the "83mm" version, along with their "68/73mm adaptor kit". If you have old ISIS cranks, use a 73x128mm.
If you are using the 135x10 QR dropouts, you want a 50-51mm chainline. Pretty much any external bearing crankset is available in this size- Truvativ, shimano, etc.
What chainguides will fit on my Bullit?
The Bullit uses the ISCG05 interface, so most guides that are sold with these mounts should fit.
Our favorites here are the E-thirteen SRS and LG1, which will bolt on with minimal hassle. We have also tried a Gamut ISCG05 and the MRP G2 with good performance on both. Many bottom bracket mount guides should work as well, as well as the various dual-ring guides on the market.
What front derailleur is compatible with the Bullit?
It depends on which dropouts you are using. If you have the 150x12mm dropouts, and the matching wide chainline crankset, you need the Saint M805 top swing, top pull, 34.9mm derailleur. If you are using the 135mm dropouts, just use a typical shimano 34.9, top swing, top pull. The saint front derailleur is not compatible with 50-51mm chainline cranks.
What is the largest tire that will fit into the frame?
Tires seem to vary so widely these days that we hate to give concrete numbers. 95% of 2.5" tires will fit in there, and definitely any 2.3" tires. We designed the Bullit with short chainstays (for its pivot location and amount of travel), and using a very tall tire (a kenda nevegal 2.7" for instance) can cause interference issues- especially with the DHX air shock.
