Cluster basics

50.4 Cluster Made by: eaglerock
Description: "This cluster is for all bikes using the 50.4 BCD spiderless cranksets, where the outer ring attaches to the crankarm through five bolts at 50.4mm BCD. This style of crankset goes back as far as the '20s, and was used in both cottered and cotterless cranks for its wide range of chainrings (26-64T in the standard TA range, with rings up to 100T for special builds). Specialites TA Criterium and Pro V, Stronglight 49A and D, Sugino PX, Velo Orange, the freakshow Lambert, single/double/triple/quadruple rings; look for five bolts right in tight around the bottom bracket spindle."
