The original Arundel shape with two wrapped arms works well in stainless steel because there is twice as much spring tension holding the bottle. More "springy" grip equals less difficulty getting a drink, yet less chance of the bottle flying out. We use 4.2mm stainless tubing which saves some weight and isn't too stiff. So, you get a timeless look that works great for a bargain price. In the Arundel tradition, we strive to make cool bike parts that work.
