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

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
