Jackal FAQs
What size headset does the Jackal use?
1 1/8"
What fork should I use on my Jackal?
The Jackal was designed primarily for a 100mm fork, but is strong enough for 160mm
Can I run my Jackal as a single speed?
Absolutely. We make horizontal dropouts with a sliding disc brake mount for single speed use. Give your distributor a call to order, or us if you are in the US or Canada.
What cranks/bb should I use for my Jackal?
The best way to set up the Jackal is to use Truvativ Howitzer cranks. Our favorite is the holzfeller OCT, but the hussafelt will work too. Get the 51mm chainline version for a 73mm bb shell.
If you are using an ISIS crank, get a 73/118mm bb. If you want to run a guide, get the 73E x 118mm. Most external bearing cranks will work, with the Saint probably being the best suited for the Jackal. Some cranks can be a little narrow where they pass the chainstays, and will rub on occasion. We haven't tried every crank out there, so we can't give you model-by-model advice. Your best bet is to stay with a stiff, strong crank that won't flex. Stay away from XC cranks like XTR or the Truvativ Stylo.
Can I use a chainguide on the Jackal?
Sure, a guide is recommended for multispeed drivetrains (rear derailleur equipped) if you are riding the bike hard. A guide is not needed if you use our horizontal dropouts for a singlespeed drivetrain. The best guide that we have tried is the E thirteen SRS. It will require some minor modification (filing) to the boomerang and ISCG adaptor, but will work beautifully once you get it on there. Make sure you get a 73E x 118mm bb if you are using ISIS drive.
What is the biggest chainring I can use on the Jackal?
The Jackal is designed for a maximum chainring of 38t. Anything bigger will interfere with the chainstay yoke.
Can I use 24" wheels on the Jackal?
The Jackal was designed specifically for 26" wheels, and the geometry is ideal with that size. However, 24" wheels will fit if you want.
Can I use a front derailleur on the Jackal?
No, the Jackal is strictly for single chainrings.
What size seatpost does the Jackal use?
The Jackal uses a 30.9mm seatpost, and a 34.9mm seatcollar. The post must always be inserted a minimum of 4".
