By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpgrade your pedals and love your bike more\u003c\/strong\u003e - Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eKey specs\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth
