The Fiamma Bike Block Pro 1 in grey represents a significant upgrade over basic bike securing methods, offering a front clasp system that grips tubes from 25mm to 80mm diameter. This range covers everything from lightweight road bikes to chunky mountain bike frames, including the increasingly popular oval-profiled tubes found on modern bikes. The large contact base spreads pressure across a wider area, preventing the frame damage that smaller clamps often cause during travel. When you're heading to campsites with prized bikes worth hundreds or thousands of pounds, this protection matters.
Compatibility extends across all Carry-Bike models, making this a straightforward retrofit if you're upgrading from older Fiamma clamps or adding extra capacity to your existing rack. The 12.5cm to 17cm adjustable reach accommodates different frame geometries without forcing awkward positioning. Installation takes seconds once you've set the initial reach distance for your bike, and the quick-release mechanism means you can remove bikes at service stations or overnight stops without tools. The grey finish works well with most vehicle colours and doesn't show road dirt as readily as lighter options. Fiamma manufactures this in Italy using reinforced materials designed for the constant vibration and road shock that motorhome-mounted bike racks endure.
This bike securing system has proven itself across thousands of European touring trips, where rougher road surfaces test every component. The Pro 1 designation indicates this sits in Fiamma's premium range, built for regular use rather than occasional weekend trips. If you're planning extended tours or frequently transport expensive bikes, the engineering quality here provides proper peace of mind. The grey version matches well with Fiamma's standard Carry-Bike rack finish, creating a cohesive look on your motorhome or caravan's rear.

Frequently Asked Questions
Which Fiamma Carry-Bike models accept the Bike Block Pro 1?
The Bike Block Pro 1 fits all Fiamma Carry-Bike rack models, including Carry-Bike XL A Pro, Carry-Bike VW T5, Carry-Bike Caravan XL A Pro, and older models like the Carry-Bike 200DJ. The universal mounting system means you can use these clamps across different rack generations, though you should verify your rack has the standard Fiamma rail system rather than earlier clip-on designs from pre-2010 models.
Will this clamp fit carbon fibre bike frames safely?
The large non-scratch base distributes pressure across a wider contact area than standard clamps, making it suitable for carbon frames when properly adjusted. The soft-touch material prevents surface damage, though many carbon bike owners add frame protection tape at contact points as standard practice. The key is setting the clamp tension correctly - tight enough to prevent movement during travel but not over-compressed, which you test by ensuring the bike doesn't shift when you push it firmly but the frame shows no stress marks.
How do you adjust the 12.5cm to 17cm reach distance?
The Bike Block Pro 1 has an adjustable arm that extends from the mounting rail to the clamp mechanism. You loosen the locking mechanism at the base, slide the arm to your required reach distance to position the clamp at the correct point on your bike frame (typically the crossbar or down tube), then retighten the lock. This adjustment accommodates different frame sizes and geometries, from compact ladies' step-through frames to large mountain bikes with extended wheelbases. Once set for your specific bikes, you rarely need to readjust unless you're carrying completely different bike types.
Can you secure electric bikes with this clamp system?
Electric bikes work with the Bike Block Pro 1 provided your Carry-Bike rack has sufficient weight capacity for the combined load. Most e-bikes have tube diameters within the 25-80mm range this clamp handles, including the chunkier down tubes some manufacturers use. The main limitation comes from your rack's maximum weight rating rather than the clamp itself - standard Carry-Bike racks typically support up to 30kg per bike, while many e-bikes weigh 20-28kg before adding luggage. Check your specific rack's weight limit and consider whether you need Fiamma's heavy-duty Carry-Bike E-Bike model designed for heavier electric bikes.
What makes the Pro 1 different from standard Fiamma bike clamps?
The Pro 1 designation indicates reinforced construction with stronger materials at stress points, a larger contact base for better frame protection, and improved quick-release mechanism that operates smoothly even after years of use. Standard Fiamma clamps use smaller contact points and lighter-duty plastic components adequate for occasional use, while the Pro 1 range targets regular tourers and full-time motorhomers who need components lasting through constant loading cycles and rougher road conditions. The reach adjustment system also offers more precise positioning compared to basic models with fixed or limited adjustment ranges.
Do you need one Bike Block Pro 1 per bike or more?
You need one Bike Block Pro 1 per bike as your primary frame securing point. Most Carry-Bike racks come with basic wheel holders or straps that secure the wheels separately, while the Bike Block Pro 1 holds the frame itself. Some cyclists add a second clamp for extra security on expensive bikes or particularly rough routes, positioning one on the down tube and another on the seat tube, though this requires enough rail space on your Carry-Bike rack. The single-clamp setup works perfectly well for normal touring provided you also use the wheel retention system your rack includes.
