Saracen can lay claim to being one of the very first British mountain bike companies, and certainly the first to get one of their bikes to the top of an actual mountain. Started in 1983 by Brian Staples, the company were a few years behind the USA who already had a number of established mountain bike brands, but they built a nicely specced bike with good quality Suntour, and then Shimano gears. They achieved a huge marketing boost when cousins Nick and Richard Crane rode two Saracens up Mount Kilimanjaro in 1984, proving how tough and versatile the mountain bike was. Soon after, the company was bought by Bluemels and later sold on again, they sold a huge number of bikes through the 80s and 90s but disappeared to be relaunched in the early 2000s.

The Trekker sat in the middle of Saracen's MTB range from 1987 into the early 90s offering their expertise in frame design at a lower price point. It started off as a Tange steel frame with U brakes front and rear, and later moved to an aluminium frame, equipped with hydraulic rim brakes by 1991.

From 1987, this is the first version of the Trekker and is in great condition for its age with the 'maize yellow' paint and original decals still looking good. Built from Tange steel tubing and designed for U brakes front and rear, this could be built up into a really versatile every day bike, or put back to its original guise as an all terrain mountain climber.

The frame's been carefully checked by one of our mechanics to confirm the alignment's correct and there's no damage to the threads. If there are any minor issues worth noting we will do so in the overview section below. Please take a good look at the detailed photos so you can see the cosmetic condition of the frame before you buy.

Seat Tube (ctc) - we measure from the centre of the bottom bracket shell up to the centre line of the top tube to give a consistent measurement regardless of frame design (ctc means centre to centre).

Top Tube (ctc) - this is measured from the centre of the head tube to the centre of the seat tube, along the centre of the top tube.

Chainstay Length - measured from the centre of the bottom bracket shell to the centre point of the rear dropout.

Wheelbase - measured from the centre of the front fork dropout to the centre point of the rear dropout.

Front & Rear Spacing - measured from the inside of one dropout to the other. The dropouts on steel frames can be stretched or squeezed a few mm but it's always best to avoid this if possible, aluminium or carbon frames should never be stretched.
