A new era of compact cyclo-computers: Newly designed circuitry & increased efficiency allows for a smaller battery, so the Strada Slimline cyclo-computer & sensor can be thinner & lighter. The head unit has a 23% bigger screen, yet is 35% thinner & lighter. The Strada Slimline is not only the sleekest, most aerodynamic cyclo-computer in over 30 years of Cateye innovation, it is also the most efficient; using smaller batteries it consumes up to 75% less energy. The tiny speed sensor is 47% thinner & fits seamlessly inside the fork stay. For those that appreciate great lines & sleek looks on their bike, the Strada Slimline ticks all the boxes. IMPORTANT: The included speed sensor may not be used with bikes that have a large space between the front fork & spoke. The clearance between the front fork face & spoke must be 12-17mm. If your bike has measurements outside of that spectrum, Wiggle recommends the use of a Cateye SPD-01 analog speed sensor, which is also compatible with the Strada Slimline.
