The COAL is our most versatile bike and everyday favorite. The bike has 160 mm travel and rolls on 650b wheels. The highly progressive suspension design is a refined version of the HERB 160. It provides excellent ground feedback and control, even in the roughest terrain. The careful placement of the main pivot in a forward position eliminates pedaling influences. The COAL maintains short chain stays, features a longer top tube, slacker head angle and lower bottom bracket. Designing every frame part from scratch, we shaved off the unnecessary weight and kept the frame strong and stiff in the important places. This bike will take you anywhere and beyond.
The frame kit is available with Rock Shox Monarch Plus RC3 DebonAir, Monarch RC DebonAir, Vivid Air R2C, Canecreek DB Inline CS and Double Barrel Air CS shock options.
Geometry and Sizing
Geometry is one of the key factors when designing a bike, because it affects the riding qualities in a big way. Correct reach, seat angle and bottom bracket height will give you a good position in the bike. Head angle and chain stay length will affect the maneuverability of your bike. The 65 degree head angle will allow you to commit to berms with ease and confidence. The 428 mm short chain stays affect the vertical maneuverability, making it easy to manual and take off on small lips. The lightness of the frame adds up to the liveliness of the ride.
For proper sizing we offer the frame in four sizes, ranging from small to x-large. Each frame size is optimized for low stand over height and a short seat tube. The short seat tubes allow everyone to use dropper seat posts with plenty of travel. New for the COAL is the steeper 75 degree seat angle which boosts pedal efficiency. Modern frames typically face the challenge of short chain stays, which can lead to collisions of the tire with the seat tube. Therefore the seat tube is moved forward and slightly angled backwards. At a certain extension the actual seat tube center line meets with the theoretical one, which starts from the bottom bracket center. The COAL frame is the first frame in our line up to reflect this difficulty. Every frame size has a different actual seat angle, which will create an effective 75 degree seat angle at the extension, that is typical for the rider size appropriate to the frame size. This way we have to manufacture many frame parts in size specific versions, but it is worth the effort.
Choosing the correct frame size is done in the most reliable way by test riding the bike. We offer this possibility in our show room and on many testivals. You may also refer to our sizing guidelines: small from 152 – 166 cm, medium 164-180 cm, large 178 – 190 cm, x-large 188-202 cm. These recommendations are based on a stem length of 50 mm. If you are in doubt about the correct frame size, don´t hesitate to contact us.
Material and Frame Design
Front and rear triangle of the COAL are welded from tubes, profiles and CNC machined parts made of 6013 aluminum. In the heat threated condition this alloy has significantly improved fatigue characteristics compared to traditional 7005 and 6061 aluminum alloys. Combined with the smooth welding lines, which reduce stress concentrations at the transition from tube to weld seam, this material is one big factor that keeps the weight down.
The extensive machining of many frame parts add up to the lighter weight of 2,89 kg. The tubes are custom butted for the COAL in order to provide load specific wall thicknesses for each section of the tube. The profiles for the rear triangle are custom drawn with variable wall thickness across their section. This allows for a slimmer yet stiff construction. The whole upper linkage has been slimmed down with regard to its lateral extension to improve the ergonomics.
The bearings we use, are full complement sealed precision bearings. Full complement means, that there is no cage retaining the balls. Therefore it is possible to use more balls, which increases the load capacity and stiffness of the bearing. All bolt heads of the linkage are flush and provide good protection for the bearings against hose water and dirt by creating a labyrinth. The small holes can be used to lube the bearings. The lube will displace the water and protect the bearings from corrosion.
Dropouts and Through Axle
The COAL allows to fit 142 mm and 148 mm wide hubs. The adjustment is made by a small insert on the disk brake side and the matching derailleur eye. For added cross compatibility we have changed the axle to a standard X12-Type which exists in versions with and without quick release. Independently from the hub width the axle must be for 148 mm width. The thread for the axle is placed in an insert on the drive side. This allows repair in case you strip the threads.
The disc brake mount is now integrated with the drop out and provides a mounting position for Postmount 180 brakes. There are threads in the drop out, because it is the lightest option. In case you damage the threads, the drop outs have pockets to fit barrel nuts, which means you can easily continue to use your frame. The added weight for the longer bolts and barrel nut applies just in case you need them.
For 142 mm wide hub configurations it is necessary to use a special 3 mm thick spacer which is placed between the hub and the disc. The spacer will position the disc in the proper position to work with the PM180 brake mount. The spacer is provided with each frame.
Bottom Bracket and ISCG Mount
The bottom bracket is a conventional, threaded BSA type in 73 mm width. The bottom bracket shell, the main pivot housing and the ISCG 05 tabs are machined from a single piece. The bottom bracket area offers enough clearance to fit regular and Boost crank sets. The only combination we do not recommend is a Boost crank with a 142 mm rear wheel, all other combinations are good.
The head tube is fully CNC machined and designed to match with Zerostack type headsets (ZS44 top, ZS56 bottom).
The cable for the dropper post runs internally through the downtube and seat tube. The shift and brake cables run on the down tube. They are bolt on type, which means you can swap them according to your needs – for example 3 cables if you run a remotely actuated lockout. A bottle cage can be mounted on the down tube.
The shifting is crisp, because the shift cable runs almost straight. Near the main pivot it runs through the stay of the rear triangle and continues it way on the chain stay. A proper chain stay protector which will also cover the cable is in the works.
Frame decals are available in various colors. Our standard decal colors are black decals on black frames, blue decals on blue frames and red decals on red frames. If you want to personalize your decal color, feel free to choose one of the colors below.
26 Inch Compatibility
The COAL is designed for 650b but with small changes it is very well suited for 26 inch. To compensate for the smaller wheel diameter, there is a longer link which will adjust the position of the rear wheel accordingly. For the front we offer a special head set cup. This cup has an increased stack height and will compensate the smaller wheel diameter. The result will be minimal geometry changes (less than 0,5°) and almost the same bottom bracket height. When purchasing the frame only, you can choose the option for the longer Link free of charge.

|A note to horizontal top tube length comparisons:|
|The horizontal top tube length is measured from the center of the upper end of the head tube to the seat tube center line. With modern full suspension frames showing a difference between actual and effective seat angle these values have become difficult to compare. It needs to be clearly indicated if the measurement is taken with the actual or effective seat tube center line. The effective one is much more relevant.|

BIKE 10/2016 (Germany) – “VERY GOOD”
“Very good” for the LAST COAL Enduro bike! Thanks to BIKE Magazin for the review. Here is a short quote:
“The Coal SL knows no limits downhill. A balanced geometry and an outstanding rear suspension give huge reserves in difficult terrain. In steep terrain the flat steering angle provides a lot of security, the very short chain stays make the bike agile and playful.”(translated)
“Sehr gut” für das LAST COAL Endurobike! Danke ans BIKE Magazin für den Test. Hier ein kurzer Auszug:
“Das Coal SL kennt bergab keine Grenzen. Eine ausgewogene Geometrie und ein überragender Hinterbau verleihen im schwierigen Gelände enorme Reserven. Im steilen Gelände bietet der flache Lenkwinkel viel Sicherheit, die sehr kurzen Kettenstreben machen das Bike wendig und verspielt.”
