Read about more about Handsling






"I am blown away by the performance of the bike in all situations flats, descents, acceleration and even more astonished by the improvement in my climbing... friends are now questioning what has happened to their performance! In total transparency I tell them “it’s not me, it’s the bike”."

"I have finally today finished building my Handsling. I’m just back from its first ride. And WOW. What a great bike. So smooth yet fast and stiff. Can’t wait to get out and ride it some more over the weekend. You really have designed a great bike here. As I say blown away with how it rides. It rides as well maybe even slightly better than my S works tarmac haha."

"I was looking for a high-performance road bike for amateur races and triathlons, but also club rides and blasting around the local lanes. I just don’t get how they made A1R0evo so stiff and responsive, but also so comfortable. I went for 28c tyres and the bike ploughs through road debris and potholes. The ride is assured and comes alive when you’re going full gas.”

"Just wanted to follow up now that it's been almost six months since I received the A1R0evo, weather is starting to turn for the better and I have been able to get out and ride more consistently with the earlier sunrises. The new bike rides great! I've been having a blast and riding much faster on my solo training rides which the new rig. I am very pleased indeed."
