Can a bike designed for the road still perform on dirt?

Some road bikes are capable of being adapted; the Astra was created to be whatever you need it to be... striking the perfect balance between road racing and the rough stuff, welcome to All-Road.

The UCI Approved Astra maintains its vocation of road cycling but increases stability and comfort. It's light, but without pushing the carbon to its limits, preserving Basso's racing DNA but makes it transversal, for those who are not professional athletes, but who want to ride their bikes every day. The new frame features dropped seatstays, a 12mm higher stack height and 3mm shorter reach, creating a slightly more relaxed riding experience. The 35mm tyre clearance allows you to mount wider tyres and venture beyond the tarmac on to light dirt roads.

Features & Benefits

3k Toray Ca High Modulus Carbon Fibre The frame is produced entirely in-house, by skilled hands at Basso Italy, its features are designed to amplify the fun factor, for those who just want to get in the saddle, no matter what their definition of riding. Basso was among the first bike brands to research, develop and employ carbon in its frames, researching new methods and techniques to continually improve performance, reliability, and durability.

Paradigma Integration System Multiple cables running through a tight space often results in slow and heavy steering. Basso has been able to integrate internal routing whilst maintaining steering lightness and precise handling. The body of the Paradigma Stem remains cable free, so can be removed at any time without the need to disconnect the cables, making it easier to maintain your bike, transport it in a travel case or bag, or change the length of your stem.

3B Clamp System Gen 2: A totally hidden seatpost fixing solution that is invisible on the frame, intertwining technological and aesthetic innovation. This lightweight and strong integrated clamping solution offers the additional benefit of an anti-vibration function, further improving your riding experience by elevating comfort on uneven and bumpy surfaces.

Perfect size and weight with compact size
Style: Rack with 3 Pairs (3, 5, and 8 Pound)
I purchased the Amazon Basics Neoprene Dumbbell Hand Weights specifically for Pilates, and they’ve been a great addition to my routine. The size and weight are perfect for controlled movements, helping with muscle toning without feeling too bulky or awkward. The neoprene coating gives them a comfortable, non-slip grip, which is especially important during longer sessions or when your hands get a little sweaty. They feel secure and easy to hold through a full workout. I also like the shape—they don’t roll around on the floor, which makes transitions between exercises smoother and less frustrating. They’re compact enough to store easily but still feel durable and well-made. Overall, these are a simple, affordable, and effective option for Pilates or light strength training. I’d definitely recommend them for anyone looking to add a little resistance to their workouts without overcomplicating things.

Good purchase
Style: 3 Pound, Pair
These are just the right weight for me to start gaining muscle back in my arms, after a large weight loss. They are of good quality, they are covered in a nice rubber like coating that is soft to the touch. They are small enough that i can take them with me when I travel. My dog has got hold of them a couple times and played with them, and they held up just fine without any damage.

Solid, grippy, and they don’t roll away!
Style: 10 Pound, Pair
I bought these because I’m finally trying to build a consistent home workout routine and didn't want to drop a fortune on name-brand weights. I’ve been using this 10lb pair for about a month now for everything from overhead presses to lunges, and honestly, they’re exactly what I was looking for. The Pros: • That Neoprene Grip: The coating is fantastic. Even when my hands get pretty sweaty halfway through a workout, I don’t feel like I’m going to drop them. It’s a much "softer" feel than cold metal or hard plastic. • The Hex Shape: This is a small detail that makes a huge difference. Since the ends are hexagonal, they don't roll across the floor when I set them down between sets. They also stay put if I’m using them for "renegade rows" or floor work. • Compact Size: They aren’t bulky. I can easily shove them under my bed or in the corner of the closet when I’m done. • No Weird Odor: I was worried they might smell like a tire factory (which happens with some rubber-coated weights), but these had almost no scent right out of the box. The Cons: • Handle Diameter: The handles are a little on the thicker side. I have medium-sized hands and it’s fine, but if you have very small hands, they might feel a bit chunky to wrap your fingers all the way around. • Color Scuffs: The navy blue looks great, but if you clank them together or drop them on concrete, the coating can scuff or show dust pretty easily. The Verdict: If you just need a reliable set of weights for HIIT, Pilates, or general strength training, these are a no-brainer. You're basically getting gym-quality equipment for a fraction of the price. I’ll probably be back for the 15lb set in a few months!

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty. The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home. Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down. They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price. If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.
