The Fiamma Bike Block Pro 3 secures bicycles to Fiamma Carry-Bike racks with a smart rotating clamp system that works with both round and oval bike frames between 25mm and 100mm diameter. This 2023 redesigned version features 360-degree rotating ends that let you position your bike at the optimal angle for loading, while the curved aluminium tube makes attachment straightforward even in tight spaces. The TÜV-approved design includes a non-scratch protective base and works with all Carry-Bike models, from compact motorhome racks to larger caravan-mounted systems.
The Italian-made unit weighs just 400 grams but delivers secure fixing through its dual-action system: the main clamp grips your bike frame while a separate locking knob secures the entire assembly to the Carry-Bike's 28-35mm diameter rail. This eliminates the wobble and frame movement that cheaper clamps often allow during travel. Caravanners and motorhome owners find the 360-degree rotation particularly useful when mounting bikes with awkward frame geometries or when loading multiple bikes in confined spaces beside the vehicle.
The deep black finish matches most modern Carry-Bike racks and resists UV degradation better than painted alternatives. Installation takes seconds without tools for the bike attachment itself, though you'll want to ensure the fixing knob is properly tightened to the Carry-Bike rail before setting off. The clamp accommodates everything from lightweight road bikes with slim tubes to mountain bikes with chunky downtubes, making it a practical choice for families with different bike types.

Frequently Asked Questions
Which Fiamma Carry-Bike racks does the Bike Block Pro 3 fit?
The Bike Block Pro 3 fits all Fiamma Carry-Bike models including Carry-Bike Pro, Carry-Bike XL, Carry-Bike Caravan, and Carry-Bike VW T5/T6 versions. The locking clamp is designed for the standard 28-35mm diameter rails used across the entire Carry-Bike range, so compatibility is universal regardless of whether you have a motorhome, caravan, or van-specific rack. If you have a Carry-Bike from any year, this will fit.
What bike frame sizes will the 25-100mm clamp accommodate?
The 25-100mm range covers virtually all adult and child bike frames. Road bikes typically have 25-35mm diameter top tubes or down tubes, mountain bikes run 30-50mm, and chunky electric bike frames with integrated batteries can reach 80-100mm. The clamp opens wide enough for oval-shaped aero frames and unusual frame geometries. If your bike has a standard diamond frame with a horizontal top tube or sloping tube, this will secure it. BMX bikes with very thick tubes and some specialist cargo bikes are at the upper limit.
How does the 360-degree rotation work and why is it useful?
The clamp ends rotate independently on the aluminium tube, letting you angle the bike to clear obstacles like rear doors, spare wheels, or adjacent bikes. This rotation means you can load bikes at awkward angles then twist them into the optimal travelling position. Motorhome owners find this particularly useful when the bike rack sits close to the rear door or when loading bikes with unusual handlebar widths. The rotation locks in place once you tighten the clamp, so bikes stay in position during travel.
What changed in the 2023 restyled model compared to older Bike Block Pro versions?
The 2023 redesign improved the locking mechanism with a larger fixing knob that provides better grip and torque when securing the unit to the Carry-Bike rail. The curved aluminium tube profile was refined to reduce weight whilst maintaining strength, dropping to 400 grams from the previous 450-gram design. The non-scratch base material was updated to a more durable compound that resists UV degradation better than the earlier version. The core functionality remains the same, so the 2023 model fits the same Carry-Bike rails and bike frames as previous versions.
Do I need additional straps or locks to secure my bike with the Bike Block Pro 3?
The Bike Block Pro 3 secures the bike frame to the Carry-Bike rail, but you need separate wheel straps to prevent the wheels moving during travel. Fiamma sells dedicated wheel straps that attach to the Carry-Bike's lower rail. For security against theft, you'll want a separate bike lock since the Bike Block's clamping system is designed for transport stability rather than anti-theft protection. Most motorhome owners use a D-lock or cable lock through the bike frame and the Carry-Bike structure when parked.
Will the curved tube design fit all Carry-Bike rail positions?
The curved aluminium tube is designed to work with the standard Carry-Bike rail spacing, whether you mount it in the upper or lower bike positions. The curve allows clearance for the bike frame whilst keeping the clamp mechanism close to the rail for maximum stability. If you're mounting multiple bikes, the curve prevents the Bike Blocks from interfering with each other when positioned side by side. The tube length is optimised for the typical distance between the Carry-Bike rail and where most bike frames naturally sit.
What does TÜV approval mean for this bike clamp?
TÜV certification means the Bike Block Pro 3 has been independently tested by the German technical inspection authority for mechanical strength, durability, and safety during transport. The testing includes vibration tests that simulate thousands of miles of motorway travel, load tests to verify it holds bikes securely at motorway speeds, and material testing to confirm the components resist UV degradation and temperature extremes. This certification is recognised across Europe and confirms the product meets the safety standards required for carrying loads on vehicles.
Can I use the Bike Block Pro 3 with carbon fibre bike frames?
The non-scratch base protects frame finishes including carbon fibre, but you should position the clamp on reinforced areas of carbon frames rather than thin-walled sections. Most carbon road bikes have reinforced zones where accessories and clamps are intended to attach. Check your bike manufacturer's guidelines about clamping locations. The Bike Block's clamp applies distributed pressure rather than point loads, which is safer for carbon frames than some cheaper clamps. Many cyclists with expensive carbon bikes use frame protectors or old inner tube sections as additional protection under any clamp.
