“The CLAY is playful and easy to handle. The suspension feels much better than you would expect of a bike with this amount of travel.“
Jörg Heydt, LAST co-owner, about his experience while racing and road tripping with the 140 mm travel CLAY prototype all season long. Responsible for the efficient suspension is the rocker actuated suspension system, that applies a metric shock for the damping. The linkage allows to tune the force vs displacement curve independent of other aspects – for example the path of the rear axle. Mid travel the characteristic is linear with starting progression, which increases to a profound progression towards the end. The result is great feedback from the terrain, allowing you to use even small features to get airborne and push efficiently through berms.
The frame kit is available with Rock Shox Deluxe, Superdeluxe and Canecreek DB Inline / DB Air [IL] shock options in 210×55 mm size. Complete bikes are available in 4 builds that can be customized to match your size and ridind style.
Geometry and Sizing
The CLAY-Geometry is characterized by the slack head angle of 65,2°, providing control and safety at the edge of grip. This comes combined with a steep seat angle of 75,3° for a great climbing position. The short 429 mm (16 7/8 inch) chain stay length makes manuals very easy. The top tube lengths are moderate; they contribute to make the CLAY a very playful ride.
The geometry is based on a 150 mm travel fork and regular 27,5 inch tires, no wagon wheels and no Plus tires for the CLAY!
„Our FASTFORWARD Enduro-Hardtail has given proof that Fahrvergnügen depends on good geometry that matches the wheels size and not on travel. With regard to geometry, frame stiffness, reliability and durability we followed a no compromise approach. The 27,5 inch bike is designed to suit our personal riding style: playful, often off the ground and with pleasure sideways.” Jochen Forstmann founder and co-owner of LAST.

Material and Frame Design
Front and rear triangle of the CLAY 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 and makes this Trail bike very strong. The the CLAY frame fulfills all test criteria to get category 4 approval. This ASTM category is typically for enduro bikes, while trail bikes are typically category 3. The logical result is that bike park adventures and racing are allowed applications for the CLAY – as long as the component spec is accordingly!
The extensive machining of many frame parts adds up to the light weight of 2,9 kg. The tubes are custom butted for the CLAY 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 bearings we use, are full complement sealed precision bearings, made of stainless steel by Endurobearings. 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. These arrangements provide a long riding period before getting wrenches out for the first service.
Dropouts and Through Axle
The CLAY 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 through axle thread in the swing arm is realized in a replaceable insert, no problem to change it should the threads get damaged by debris when changing the wheel in worst weather conditions.
The disc brake mount is 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.
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 shock 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.
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.

|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.|

LAST suspension frames are designed for use on non motorized bicycles only. The frame is inceredibly strong, but incidental or repeated abuse or crashes can damage the frame and reduce it’s structural strength and useful life. Remember that extreme riding is dangerous and that you ride on your own risk. Use safety gear and ride carefully.
The LAST CLAY is a Trail bike but due to it´s strong frame it is intended for use according to category 4 desribed in ASTM F2043-13 Standard Classification for Bicycle Usage.
|Category 1 – This is a set of conditions for the operation of a bicycle on a regular paved surface where the tires are intended to maintain ground contact.|
|Category 2 – This is a set of conditions for the operation of a bicycle that includes Condition 1 as well as unpaved and gravel roads and trails with moderate grades. In this set of conditions, contact with irregular terrain and loss of tire contact with the ground may occur. Drops are intended to be limited to 15cm (6“) or less.|
|Category 3 – This is a set of conditions for operation of a bicycle that includes Condition 1 and Condition 2 as well as rough trails, rough unpaved roads, and rough terrain and unimproved trails that require technical skills. Jumps and drops are intended to be less than 61cm (24“).|
|Category 4 – This is a set of conditions for operation of a bicycle that includes Conditions 1, 2, and 3, or downhill grades on rough trails at speeds less than 40 km/h (25 mph), or both. Jumps are intended to be less than 122cm (48“).|
|Category 5 – This is a set of conditions for operation of a bicycle that includes Conditions 1, 2, 3, and 4; extreme jumping; or downhill grades on rough trails at speeds in excess of 40 km/h (25 mph); or a combination thereof.|
