Ellsworth Dare

Ellsworth was recently purchased by BST Nano Carbon, a composite company based in San Diego, California, with a diverse background in developing composite technologies for the aerospace, automotive and sporting goods industries.
The company will soon begin production of its carbon frames in the US. However, the redesigned Ellsworth Dare is still produced overseas.
In addition to reworking the Dare in carbon and adding 27.5in wheels, Ellsworth opted to make the rear suspension highly adjustable — the Dare can be configured for 225mm, 180mm or 160mm of rear suspension travel by swapping the length and location of the shock.
As shown here in full gravity mode with 225mm of rear wheel travel via a Fox RC2 coil, the bike has a 63 degree head tube, a 14in high bottom bracket and 17.5in chainstays.
The Dare frame with Fox RC2 shock will retail for US$3,696.
Chumba returns

Chumba is back under new ownership. The company has moved from Southern California to Austin, Texas, and has brought all manufacturing back to the US. The company was showing off its latest model, the Ursa, a 29+ hardtail constructed from True Temper steel tubing.
Unlike the handful of other 29+ models on the market from brands such as Surly, Niner and Singular, the Ursa uses a 150x12mm rear end. This wider spacing necessitates the use of an 83mm-wide bottom bracket shell, but increases chain clearance.
The Ursa frame retails for US$1,195. Complete builds range in price from a US$3,195 singlespeed version to a US$3,495 Shimano XT-equipped model.
