Why We Like The All-City Cycles Space Horse Microshift Gravel Bike

From your daily urban commute to a weekend of touring, the versatile All-City Cycles Space Horse Microshift Gravel Bike is ready for the adventure. Its frame is constructed with durable 612 select tubing, All-City Cycles' proprietary blend of double-butted 4130 Chromoly steel, to allow for a comfortable, fun ride. With a moderate reach and head tube angle, you are placed in a riding position that is ideal for longer rides. Complete with front and back mounts for your fenders and racks, ensuring you have everything needed for a bikepacking trip won't be an issue.

The Space Horse Microshift Gravel Bike features the microSHIFT Advent X, 10-speed groupset, offering a big range of MTB gearing with minimal weight and reliable shifting no matter the conditions. Its Tektro HD-R280 flat-mount hydraulic disc brake system, designed for road and lifestyle riding, offers smooth and controlled stops with easy adjustment and maintenance. Whether hitting rough gravel patches or smooth sections of tarmac, the WTB ST i19 wheelset with Teravail Washburn tires are prepared to take you through it all with ease.

*Due to a high demand in the global supply chain and bike industry since the start of the pandemic, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be of equal or better spec level. If you have any questions, reach out to a Gearhead by chatting online or calling 1-888-276-7130.
