And here it is! After 7 months of collecting parts for a very specific bike build, I can finally say that as long as the bottom bracket spindle gives a proper chainline then this decaluer is the very last component needed.
I wouldn’t mind fresh decals for the rims, and crank arms, but I’ll consider those “wants” as opposed to “needs.” And those can come much later. No problem. So I think I can safely tear the shopping list up now. Let the good times roll... !
