Hey Laura,
There is a swing-away rack you can use with the Allant+ 7s Stagger that has the rear fender but not the RockyMounts AfterParty # RKY37ZR. The rear wheel holder won't be compatible with the fender at all, as its not able to secure a rack via the frame or fender - it simply won't offer the necessary stability. So instead I recommend the following:
- RockyMounts BackStage Bike Rack for 2 Bikes # RKY10002
The # RKY10002 is a wheel-mounted rack as well, but just for the front tire.... view full answer...
