The Holy Grail of Long-Travel Bikes

The Firebird is the no-compromise, Holy Grail of long-travel mountain bikes; it’s both an enduro bike that devours blazing descents and a technical climber that gains elevation astonishingly well.

For enduro racers, the tough and light Firebird’s peerless climbing traction, descending capability and instant acceleration makes it the perfect choice for the steep, punishing courses of the EWS. For park riders, the Firebird’s long front-center and short chainstay combination provides that nimble, snappy feel that encourages bold line choices yet allows you to stay in complete control at World Cup speeds.

To ensure the best sizing, we recommend that you visit your local Pivot dealer to get a professional fit and refer to our geometry chart to check your measurements. We suggest that you pick your Firebird size based on your riding style. 

The Firebird features long and low geometry with a sizing philosophy similar to the Phoenix DH. The Firebird’s reach measurements push new limits (they are long). Additionally, with both shorter seat tube and head tube measurements per size, riders have a wider range of bike sizes to choose from depending on your riding style and preferences. Some riders may find it comfortable to go up or down a size depending on their reach and stem length preferences. Below is a general guideline: 

Small: 5'4.5" – 5’9”
Medium: 5'7” –5’11”
Large: 5'10” – 6’3”
X‐Large: 6'2” +

We make it easy to get the best ride out of your Pivot bike with a simple sag indicator already installed on your bike, and this follow-along video featuring our own Bernard Kerr:

Variables in frame size, discrepancies in scale calibrations, and method of weighing (with or without pedals and such) all lead to inaccurate comparisons, so we choose not to publish our bike weights. Pivot bicycles are among the lightest available, but the weight is only one of many factors that make a great bicycle. Other aspects such as frame stiffness, strength, durability, and ride quality are just as important as weight to our engineers when designing our Hollow Core Carbon and aluminum frames. Instead of comparing grams online, we suggest you visit your local Pivot dealer and see our attention to detail, smart, high value spec, and class leading features. Bring a scale if you’d like, but take just one demo ride and you’ll feel why Pivot Cycles are the most well-rounded, highest performing bicycles on the market and in many cases, yes, it’s the lightest as well.

The Firebird uses a 30.9mm size post and features a low stand-over height and short seat tubes to allow the use of longer travel dropper posts and/or more flexibility for a wider range of rider sizes. There are some limitations that each dropper post can accommodate for each frame size based on the individual riders saddle height, so it is important to check fit before choosing the travel and model of dropper post for your Switchblade. Use the linked guide to find the right post for your bike:

The Firebird uses the Boost 148mm X 12mm hub/wheel spacing. This is a new hub design with wider flanges so you cannot take a current 135mm, 142mm, 150mm, or 157mm hub and change end caps to convert an existing hub.

Pivot uses a 1.5 thread pitch on the rear thru axle. You can order one through our online store here:

The Firebird was designed for a 170mm fork. The maximum travel length that can be used on the Firebird is 180mm travel.

The fork offset for the Firebird is 44mm.

The Firebird was designed to run 27.5” wheels with up to 2.5” tires. We are partial to the new line of Maxxis Wide Trail tires that come in either 2.4” or 2.5” depending on the model. All Firebird complete bikes come with 2.5”Maxxis Minion DHF 2.5” Wide Trail front and 2.4”Minion DHRII Wide Trail rear. The Firebird is not 27.5+ compatible.

The Firebird frame uses a 30.9mm seatpost.

The Firebird frame uses a 34.9mm or 35mm (as some manufacturers call it) seatpost clamp.

The Firebird uses an e-type Shimano side-swing style front derailleur only. Shimano produces the new e-type side-swing front derailleur in Deore and SLX for 10 speed drivetrains and XT and XTR for 11 speed drivetrains.

Yes. The Firebird features ISCG05 mounts on the frame. Most upper guides on the market will fit and you can either use the ISCG05 mounts or some of the more compact versions that attach to an E-Type front derailleur mount. For full upper and lower guides, we recommend the MRP AMG for the Firebird.

The Firebird uses a ZS (zero stack) 49.6mm top and can also accept a standard 1.5 external top cup. The lower (bottom) cup is a (zero stack) 56mm size.

The Firebird was designed for a 180mm rear rotor and features a 180mm post mount design, so you cannot fit a 160mm rotor on the Firebird. A 203mm rotor will fit with the use of a post mount caliper adapter.

No brake adapter is needed for a 180mm rotor. However, if you'd prefer to run a 203mm rotor, you would need a proper direct mount/post to post adapter to go from a 180mm to 203mm rotor.

The Firebird will accept all cranks designed for the BOOST system and compatible with a press fit 92mm bottom bracket. BOOST system means that the rear hub spacing is 148mm and the chain-rings have been shifted out approximately 3mm from where a tradition crank designed for a 142mm rear hub would be so that the chainrings will line up properly with the new position of the cassette on the 148mm rear hub.

In some cases you can run a conventional non-BOOST 1X or 2X crank. The Race Face NEXT 1X and other Cinch system 1X cranks are dual compatible between standard 142mm and 148mm Boost rear ends. Some smaller chainring combination 1X (30 and 32T) Shimano XT and XTR 11 will also work. In some cases 2X standard cranks may also work with 24/34, 26/36 and 22/36 combinations. Shimano’s new 11 Speed XTR and XT standard cranks feature both 24/34 and 26/36 chainring options which work perfectly with the Mach 6 Carbon frame as Shimano’s chainline dimensions already tend to run wider than others in the market. There may be other 2X non- boost cranks available that will work although it is dependent on specific chainline and chainring size. If the chainline is not out far enough, the front derailleur clearance may be tight when shifting into the small ring as the front derailleur mount on the Firebird is also shifted outwards to accommodate the BOOST design.

The eye-to-eye shock length is 8.5 inches and the stroke length is 2.5 inches.

The Firebird shock uses M8 through bolt hardware on the front and no hardware on the rear. Shock spacer dimensions are 22mm wide front. On the rear of the shock, the spacer hardware and bushing will need to be removed as the strut mounts directly to the shock body. Some shocks may have a different spec then the Fox shock (that the Firebird Carbon is designed for) and may not fit properly. Also, as we cannot test every shock on the market, riders assume some risk if they choose a shock that does not fit properly or is not tuned correctly for the bike. The frame is designed around a large volume air can. We run medium compression valving and medium rebound damping.

We do not recommend that you run a coil-over on your Firebird. The Firebird was designed to work with the progressiveness of an air spring. Running a coil-over shock on the Firebird Carbon will result in hard bottoming and could result in damage to the frame and shock. Additionally, the clevis design adds considerable leverage to the unsupported shock shaft and internal piston bushing on a coil shock that can result in premature wear of the shock and/or, a total failure of the shock shaft. For maximum performance and durability, we recommend staying with the Pivot spec’d FOX Float X2 shock (or DPX2 on our race builds). The Pivot Factory Racing DH World Cup team has the option of running either the FOX X2 air or coil on their DH bikes and each rider has found the air shock to offer better performance and control and ultimately faster times on the race course. However, if you want to run a different shock, then stick with an air shock such as the Rock Shox Super Delux or Vivid Air or another DH based air shock design that features a tunable spring curve. Any frame damage occurring due to shock failure from using any shock other than the Pivot supplied FOX Float X2 or DPX2 will not be covered under warranty.
