Yeti Big Top 29er Hardtail Unveiled

Yeti Big Top 29er Hardtail Unveiled

Yeti is getting into the 29er game with a hybrid (aluminum/carbon) hardtail for 2011. News of the new at Sea Otter was met with stoke and eagerness to get onboard this new big-wheeled machine. While I will not likely get onboard one until this Fall at Interbike, I will lay out the dealio here so we can all imagine how great it will ride until I get some quality time.

One of the most unique aspects of the new Yeti Big Top 29er is the hybrid frameset. This frame consists of a welded aluminum front triangle that’s mated with a carbon-fiber rear triangle. True to Yeti form, the Big Top includes a looped chainstay-to-seatstay transition — reminiscent of Yeti’s hardtails of old. While the majority of the rear triangle is carbon, the dropouts are aluminum and are capable of handling a variety of axles (like the ASR5c) and running geared or single-speed.

I just got the full specs (geometry and build kit) from the crew at Yeti, see below for details.
