Interbike tech: Tidbits from the show floor

Keywin was an early entrant into the clipless pedal market back in the 1980s. Now the brand has a new design that is very light, affordable and adjustable. Axles are available in six lengths; float can be 6 or 0 degrees and float tension also is adjustable. A titanium-axle version weights 245 grams with cleats and hardware and retails for $299. A chromoly axle version weighs 284 grams and retails for $199.

The 3-hole cleat has a huge surface area and offers a wide range of adjustment fore and aft and side to side. Photo: Steve Frothingham

The Cerevellum Hindsight is a handle-mounted monitor for a rear-view camera mounted on your seatpost. It records video in a 10-minute loop so you can have evidence of a wheel sucker — or a sideswiping vehicle. The headunit also functions as an ANT+ compatible cycling computer and can accept apps to work with SRM wattage meters or perform other function. $299, www.cerevellum.com.

The Cerevellum rear-facing camera also has a built in LED taillight. It's connected by wire to the headunit. Photo: Steve Frothingham © VeloNews.com

After being out of the U.S. market for several years because of unfavorable exchange rates, the Barbieri line of pumps and accessoriesis back. The new CarbCase seat bag has a hardshell lined with padded material to reduce rattling. Barbieri also has some superlight carbon and titanium pumps. Photo: Steve Frothingham

Physiologist Allen Lim is selling a line of drinks and energy bars that some ProTeam racers (and some VeloNews staffers) have been testing for a while now. Lim is opting for a stealthy marketing vibe for his Secret Drink Mix. The drink has a very mild flavor and packs fewer calories than some other drinks. The mild taste and fast absorption are said to encourage the athlete to drink more to get sufficient calories. The company hopes to sell through about 100 retailers. The line is also available at www.secretdrinkmix.com

The Slow Wheel is a front wheel with adjustable tension to provide a harder workout and allow riders of varying fitness levels to ride together. (We are hoping to get some in for some blind testing by some over-aggressive VeloNews lunch ride regulars ...). The adjustable tension kicks in at 10kph and disengages at 40kph for fast descending. A model with three levels of adjustment will retail for $699, a model with seven levels of adjustment will be $1,199. Photo: Steve Frothingham
