Side-entry loading. Adjustable fit. 48g. The Blackburn Sidetrack is the cage that makes hydration on the trail or commute genuinely effortless — no awkward reach, no fumbling, no excuse to skip the water.

Side-entry cages exist for one reason: your frame gets in the way. On eBikes in particular — where down tubes are wider, batteries take up space, and bag mounts crowd the frame — a traditional top-pull cage often just doesn't work. The Sidetrack solves that. Slide your bottle in from the side with one hand, and it locks in cleanly without the cage fighting you back.

The 30mm slotted bolt holes let you shift the cage up or down on the mount — useful on smaller frames or wherever a damper, cable, or motor housing eats into the clearance. It's the same adjustability found on Blackburn's higher-end Clutch Cage, just at a price that makes it easy to spec more than one on the same bike.

Available in right or left-hand entry — choose based on which side of the frame you're mounting it on. If you're unsure, get in touch and we'll help you work it out.
