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

This suit fits true to size. We got the 9-10 size in white/tan for our above average height 7 year old, and the suit was just a little big (te Amazon algorithm recommended 9-10 based on past purchases and timing. He is the large side of his 2nd grade class, despite being one of the youngest, so I would say this suit would start fitting an average 8.5-9 year old boy. The fabric is a relaxed summer fabric, so good for semi-dress relaxed events. Our tan suit (and from the weathered gray/blue/green images, I assume all of the suits) seems like a casual menswear commercial shoot. The fabric isn't scratchy and our son said it is comfortable. It includes the picket flower, but I didn't think much of that plastic bloom.
