KCNC K5 Rectangular Road RingsThey call them "rectangular" chainrings, but they are an extreme a symetric ring!! They are certainly not round!! Designed to reduce the effect of the "dead spot" as the crank arms come round top dead centre (12 and 6 o'clock). They can increase power, they can increase efficiency, they can make you pedal smoother! KCNC use what they call an ovality ratio of 1. 225 on the K5 pattern rings, with a bi radial symmetry offset by 88. 3 degrees. 110bcd 39T

Great product and fast shipping
Style: EcoFetch
Great ball launcher and ball. My dog adores it and plays with the ball even when she isn’t fetching. Fast shipping as well!

Value for your money
Style: EcoFetch
It's definitely different from the one I lost. It's taking me some time how to throw the ball correctly. It's a hit and miss but we are getting there. When I do get a good throw, it really wings it out there.

Perfect for active dogs
This is a must-have if your dog loves to fetch. It throws the ball far with very little effort and keeps your hands clean—no more slobbery chuckit balls. Lightweight, durable, and makes playtime much more fun (and less tiring for me!).
