French frame and component maker Look has introduced its 586 high modulus carbon road frameset for 2008, a completely new frame design with extended seat tube weighing just 940g, plus 340g for the Look HSC6 carbon fork.
The lugless 586 frame is 100g lighter than the lugged 595 Ultra Pro Team ridden by Team Credit Agricole.
Each Look 586 frameset includes three sets of elastomer blocks (grey - soft, red - medium, and black - firm) for the E-Post. The aero-shaped E-Post offers 30mm of offset, weighs just 213g, and is 91mm tall (max insertion to saddle rail centre). Look offers its R32 E-Post with +/- reversible 32mm offset for a more triathlon/time trial-specific position. It weighs 196g.
The carbon rear dropouts are compressed at the time when both the seat and chain stays are moulded as part of Look's one-piece engineering, resulting in a single-piece rear triangle. Look uses the same technology on its HSC6 fork tips. Look also eliminated the aluminum crown race by using an integrated carbon conical bearing set with a 45-degree race angle. And, as has been the trend for 2008, the upper head tube of the Look 586 is 1-1/8", widening out to a 1-1/4" lower.
Holding it all together in front is Look's new patented HeadFit headset system, which allows for independent headset and stem adjustment. A threaded insert on the HSC6 special steer tube, which saves 40g by eliminating the compression plug. This, according to Look, also saves a step when adjusting or swapping out a stem. A standard Shimano bottom bracket tool is all one needs to adjust the HeadFit.
The high modulus carbon frame has a replaceable aluminum rear derailleur hanger, front derailleur braze-on, standard 68mm bottom bracket width, and comes with a five-year structural warranty and one-year paint and finish warranty.
According to Ming Tan of Look Cycle USA, the 586 will be available in mid October, in red or black (pictured). Sizes range from XS to XL, and the frameset includes frame, fork, HeadFit headset, and E-Post, for $3,699US. The Look Pro E-Post tool is a stainless saw guide for Look authorized dealers only, and is needed to custom-size the 586 extended seat tube.
The new Keo Grip cleat is designed to combat the slippery duck syndrome so prevalent with Look cleats. This is good news for those who don't carry anti-slip cleat covers in their back pocket. Look has also incorporated a Memory Clip to make replacing cleats an easier and more exact process. Weight is 68g for the pair with screws and washers. Float options include 0, 4.5 or 9 degrees.

The first ride review will apear in issue 202 on sale 28th September.
