Fiamma Bike-Block Pro – Heavy-Duty Support Arms for Your Bike Rack
Ensure your bikes stay securely mounted while you’re on the move. The Fiamma Bike-Block Pro is the strongest clamping system available for securing bicycles to Fiamma Carry-Bike racks. Whether you’re heading into the mountains or across state lines, this robust arm locks your bike into place without damaging the frame.
The front clamp features a wide, non-scratch grip that accommodates both round and oval bike tubes with diameters from 1 inch to 3.15 inches (25mm to 80mm). A quick-release mechanism makes installation and removal easy-no tools required.
Choose from four color options: Red, Blue, Grey, and Black. All Bike-Block Pro arms are compatible with every Fiamma Carry-Bike model and are available in four lengths to suit your bike placement needs:
| Model | Fits Tube Diameter | Arm Reach (ft/in) |
|---|---|---|
| Bike Block 1 | 1″ – 3 1/8″ | 4 7/8″ – 6 3/4″ |
| Bike Block 2 | 1″ – 3 1/8″ | 9 1/2″ – 11″ |
| Bike Block 3 | 1″ – 3 1/8″ | 1 ft 3 1/4″ – 1 ft 4 1/2″ |
| Bike Block 4 | 1″ – 3 1/8″ | 1 ft 9 1/4″ – 1 ft 10 3/8″ |
Simply attach the Bike-Block arm to your rack, clamp it onto your bike tube, and tighten the quick strap-done. The padded grip and strap ensure your bike stays put without scratching the frame or the rack.
