The Gary Fisher HiFi trailbike will receive a carbon big brother for 2008, aptly named the HiFi Carbon. The basic elements of the original HiFi have been retained, including the company's new Genesis 2.0 front end geometry, 120mm of travel front and rear, and a simple and reliable linkage-actuated single-pivot suspension design. With the new model, however, Gary Fisher engineers set out to make what it considers to be "the finest trail bike on the market the lightest trail bike on the market."

Indeed, the new carbon fiber front triangle drops the overall frame weight of the HiFi Carbon down to just 2.14kg (4.71lb, claimed), and also adds a reported 40% improvement in stiffness-to-weight ratio. Rather than just utilize conventionally bonded shock and linkage mounts, Gary Fisher engineers integrated the aluminum hard points directly into the carbon mold in such a way as to maximize adhesive strength and carbon fiber loading. Reliability on the new-style mounts is said to be significantly improved, but the new co-molded bits are lighter as well, saving 40g on just the upper shock mount alone.

Trek previewed its take on the intriguing 69er concept at last year's Sea Otter Classic, and announced the addition of two more 69er models just as the original singlespeed models are hitting showroom floors. Travis Brown's signature model will now be joined by a geared 69er aluminum hardtail as well as a geared full-suspension Top Fuel 69er which will incorporate Trek's latest R1 rocker-link rear end.

Titanium has been virtually completely surpassed by the glamour of carbon fiber lately, but its legitimately good material properties still make it a perfectly viable candidate for high performance bicycle frames. Litespeed, in particular, is on a mission (for obvious reasons, we must say) to bring titanium back into the realm of top performance, and its new Archon road frame might go a long way to doing so.

Litespeed-sponsored Team Maxxis riders only race on the dirt, but XC standouts Geoff Kabush and Mathieu Toulouse train heavily on the road and have provided the company with a lot of valuable feedback. Litespeed's designers focused more on overall performance than the gram scale as a result and the new frame has a "stiffness-to-weight ratio in a range that [titanium] has never been," according to Brad DeVaney, Engineering Manager for American Bicycle Group. DeVaney didn't go so far as to say that it would match that of carbon fiber (and to be honest, we'd have been rather skeptical if he had), but he did concede that Litespeed's ultralight frames have historically really been better suited as climbing bikes.

DeVaney added that the current UCI weight limit also indirectly aided in the design. Since wheels and components have lightened up the point where the frame is no longer the limiting factor in hitting the minimum 6.8kg target, the ruling "lets us put more material where it's needed." As such, the roughly 1kg Archon gives up about 200g relative to Litespeed's ethereal Ghisallo, but if that extra material adds up to a sturdier feel and more precise handling, we'll gladly take it, plus it'll be a sad world when we actually consider a 1kg frame to be heavy.
