Every bike setup on a Big Days rack leans on its lower support bar, and these brackets are what tie that bar to the rack itself. Lower Bar Brackets fasten the bike support bar to your Chase Rack System — strong, stable, and built to hold, as Big Days puts it — so the bar stays put when the rack is loaded and the road turns to washboard.
It's the part to order when you're adding a lower bar to an existing rack, rebuilding a configuration around bikes, or replacing hardware that's been through a few seasons of loading. If you need the bar itself, the Small Parts – Lower Beam is sold separately: the brackets handle the mounting, the beam is the bar they hold.
Features
- Secures the bike support bar (lower beam) to the Big Days Chase Rack System
- Purpose-made for the Big Days rack platform, not adapted generic hardware
- Keeps the lower bar strong and stable under load
- Worth keeping as a spare if you reconfigure your rack between moto and bike duty
These brackets fit the Big Days Chase Rack System. Big Days maintains an installation guide and FAQ among its support resources, and the company runs its own install bay at its Orem, Utah headquarters if you'd rather have it bolted up for you. Browse more rack accessories to finish out your build.
Lower Bar Brackets FAQs
Are these compatible with my Big Days rack?
Yes — Lower Bar Brackets are made specifically to secure the bike support bar to the Big Days Chase Rack System. They're a direct accessory for the platform rather than universal hardware. If you're unsure how they fit your particular build configuration, Big Days publishes an installation guide and FAQ in its support resources.
Do I need to buy the lower bar separately?
Yes, if you don't already have one. These are the brackets that mount the bar to the rack; the bar itself is Big Days' Small Parts – Lower Beam, sold separately. If you're replacing damaged brackets on an existing setup, your current bar carries over and this is the only part you need.
What does installation involve?
The brackets attach to the Chase Rack to hold the bike support bar in place. Big Days doesn't publish a separate spec sheet for this part, but its installation guide and FAQ cover the rack system, and the company operates its own install bay in Orem, Utah if you'd rather hand the job off.
