MRP Chain Guide Seat tube CXDeveloped with World Cup powerhouse Adam Craig, the 1x (pronounced one bye) is purpose built for cross country riding with a 1x9, 1x10, 1x11 drive train. If you are running 1x and don't need a bash guard, this is the ticket. No more homemade contraptions needed! Fits seat tube sizes 28. 6, 31. 8 & 34. 9mm (with supplied rubber shims). The CX does not have the drop bracket that the MTB version does, because of the much larger chainrings that are used

I bought this for my granddaughter, who is 8 years old, and typically wears a size 8. I purchased the size 9, she likes oversized hoodies, even though the add already says it’s oversized. It was MAYyBE a size 6, it was tight on my six year old granddaughter. I sent it back, and am not reordering. I’m not going to keep guessing on sizing. I want to know that when I order the size she wears in Nike, Adidas, Target,etc. , that it’s going to be the same, and not have to keep returning items…

Loved these and they fit. Nice and warm for a chilly summer evening at the beach, and looked great with summer pastels.
