Despite a recent resurgence in popularity, oval chainrings are not new technology. Dating as far back as 1890, non-round chainrings have made numerous appearances in the marketplace, with the most in/famous being Shimano’s Biopace. More recently, oval rings enjoyed a boost in popularity when professional road racers Chris Froome and Sir Bradley Wiggins used non-round rings in their quests for Tour de France victories. And now, oval chainrings such as those offered by absoluteBLACK are seeing more use among off-road riders.
It’s no secret that bicycle light technology has improved by leaps and bounds. The current crop of lights have more power, run longer, and cost less than last year’s offerings. Whether you’re a hardcore commuter or avid recreational rider, there’s bound to be a light that fits your budget and requirements.
Lights generally fall into one of two categories–see by, and be seen lights. The former are brighter, and enable the rider ride safely in areas without ambient light sources (e.g streetlights). The latter, on the other hand, are mostly used for improving cyclists’ visibility in low-light conditions (think urban riding).
Manufacturers specify light output in lumens. Generally, the more lumens, the brighter the light. For my testing, I separated the lights by output. Those lights with a rating of less than 100 lumens were considered be seen lights, while lights rated over 100 lumens were classified as see by lights. This installment covers the lights with 100+ lumens, and Part-II will feature lights with outputs of less than 100 lumens.

Update: Speedplay has published a SYZR quick start set-up guide which you can read here.
Speedplay‘s SYZR pedals were in development for so long that many riders–myself included–wondered if the unique pedals would ever make it to market. With claims of road-worthy power transfer and superior mud-clearing ability, the San Diego-based company’s pedals achieved a near-mythical status. Then, in 2015, the wait was finally over when the SYZRs officially hit the shelves.
The SYZR may look like your standard off-road clipless pedal, but the design is anything but ordinary. For starters, Speedplay reversed the pedals’ latch mechanisms–SYZRs utilize a pivoting front latch instead of pivoting rear latch. According to Speedplay, this new latch design reduces the likelihood of accidental release when pulling hard on the pedals (because you no longer pull up against the release mechanism). Then there are the cleats. Speedplay threw convention out the window, and moved the pivot mechanism directly inside the cleat, enabling micro-adjustable float adjustment.
