There are very good grips...only nobody is using them. That's why we use LockOn grips like those used on high-quality mountain bikes. No more narrow grips, no more slipping, no cheap foam.
Hand luggage and training gear... No problem at all. The Core Wheel is tough enough for any workout and small enough for any backpack. The perfect companion at home and when travelling.
The two clips let you easily adjust the distance between the wheels without any tools: clips between the wheels create a wider track for more stability and safety, perfect for beginners and for hooking a resistance band. Clips next to the wheels result in a narrow track for more instability and a more intensive training effect.
