Mongoose beef up Teocali platform for 2011

More rear travel plus tougher frame

Mongoose's versatile Teocali trail bike range will lean a little more towards the all-mountain end of the spectrum when the 2011 model comes out later this year.

Rear wheel travel grows only slightly to a full 150mm but the all-new alloy frame should toughen things up for more heavy-duty use. In particular, linkages and pivots – whose designs were borrowed from Mongoose's gravity range – between the front and rear triangles have been substantially bolstered for a more precise feel in rough terrain and improved wheel tracking.

Tubing diameters have been increased in the swingarm and more aggressive hydroforming is used up front to further stiffen things up. In a nod to the upcoming Teocali's expanded capabilities, head tube angle has slackened to 68 degrees and Mongoose will even offer a 'Mega' variant with downhill enduro style parts, including a 160mm-travel fork.

Mongoose still intend the Teocali to be pedaled uphill most of the time, however, so they retains the model's proven FreeDrive suspension system. Though complicated looking at first glance, it's essentially a high single-pivot design in terms of axle path for good performance on square-edged bumps but without the usual negative pedalling effects.

As the suspension moves through its travel, the additional linkage at the bottom of the frame pulls the bottom bracket rearwards, thus maintaining a relatively constant effective chainstay length and essentially neutralising pedal forces. Having ridden FreeDrive-equipped machines extensively in the past, we expect the new Teocali to be a very capable rig – and likely quite fun, too.

James started as a roadie in 1990 with his high school team but switched to dirt in 1994 and has enjoyed both ever since. Anything that comes through his hands is bound to be taken apart, and those hands still sometimes smell like fork oil even though he retired from shop life in 2007. He prefers manual over automatic, fizzy over still, and the right way over the easy way.
  • Discipline: Mountain, road, cyclocross
  • Preferred Terrain: Up in the Colorado high-country where the singletrack is still single, the dirt is still brown, and the aspens are in full bloom. Also, those perfect stretches of pavement where the road snakes across the mountainside like an artist's paintbrush.
