Cohutta 29er is Across the Pond!

With the wagon-wheeled world of 29ers looking set to take the UK mtb market by force in 2012 you’re likely to see most manufacturers frantically trying to jump on the bandwagon. North America has pretty much accepted the advantages the larger wheel size straight from the inception and with sales of 29er bikes now far outweighing those of conventional 26” wheeled bikes in the States the ‘switch’ looks to have been firmly made and set. Without doubt 29ers are here to stay and 2012 looks to be the breakthrough year for them here in the UK.

Tennessee based Titanium pioneers, Litespeed aren’t new the world of 29ers, and were in fact pioneers and early adopters of the new standard, having released the much acclaimed Obed hardtail in a 29er version way back in 2007. It was time when 29er’s were still very much considered a niche, flash-in-the-pan fad, let alone a 29er made from Titanium!

With knowledge and understanding of 29” wheel applications having moved on significantly since those early days Litespeed deemed it necessary to go back to the drawing board…

Litespeed are proud to present the brand new 2012 Cohutta 29er frameset. A highly adaptable and versatile 29er platform that’ll happily tackle both trail and XC race duties depending on the spec and flavour of the build.

Litespeed Titanium models are always given a Native American name as a nod to the heritage of the area in which they’re based (Chatanooga, Tennessee). The Cohutta, rather fittingly, shares its name with a grueling 100-mile endurance mtb race (http://www.newleafadventures.com/Cohutta.html/) and also a picturesque forest that spans nearby Georgia and Tennessee.

Stars’n’stripes – Litespeed Titanium frames always have and always will be handcrafted in their factory in Chatanooga, Tennessee.

The usual immaculate welds and attention to detail we’ve come to love and expect from Litespeed are ever present on the Cohutta.

The Pressfit 30 BB allows for either oversize 30mm crankarm axles, standard 24mm diameter (via the used of aftermarket adaptors) or even an aftermarket eccentric BB (to fit the 46mm ID) for single speed duties. The Press Fit 30 system is similar to the concept that Shimano is using – a nylon sleeve/cup holds the bearings and thus does away with the fiddly snap rings of the BB30 system. It gives you a nice big BB shell area for which to attach larger chainstays, downtube and seattube, no counter miters and lastly does not require a tolerance that is +/- .001" as the bearings don’t sit directly in the BB shell of the frame. Neat!

The heatube on the Cohutta is oversize too, but like the BB it’s not for looks and the reasons for speccing it are 100% functional. The headtube measures 1.5"/49mm ID which ultimately makes the Cohutta one extremely versatile bike (suitable for either 80/100/120mm forks); allowing for fine tuning of the headtube angle (if used with the recommended Cane Creek AngleSet ZS49/EC49), accommodation any steerer tube standard (1.5", traditional 1 1/8" or 1.5" - 1 1/8" tapered) and adjustment of stack height (whether you choose to run an internal/external bearings/headset cups).

In addition to increasing torsional stiffness of the entire front triangle, the 49mm ID headtube allows for total freedom with reagrds to headset and fork selection. The above chart should help with selection and setup for the intended use.

Such are demands on a 29er frameset so different from that of the smaller wheeled 26” cousin, the Litespeed engineers have pulled out all the stops and specced exclusive, specially selected and sized 29er-specific tubing for the Cohutta (TT, DT & HT) milled by Litespeed in Tennessee to give optimum ride and performance characteristics.

The mech hange is a non-replaceable but judging by the thickness of the dropouts we don’t think it’s going to be an issue!

With x4 sizes available there should be a Cohutta for everyone – big or small (above geometry chart based on sagged bike w/ 100mm fork).

BB Size: Pressfit 30 (PF30) 73mm x 46mm internal diameter
Suitable Fork Size: 80mm / 100mm / 120mm

Frame Weights:
