To obtain a proper chainline for a boost rear hub (~52 mm), is it enough to fit a boost (3 mm offset) chainring to a 1x crankset which is originally non-boost, or is an entire boost crankset required (i.e. not only the chainring but also the crankarms)? Namely, I am buliding a boost bike and can get a very good deal for a SRAM groupset that has a non-boost DUB direct mount crankset. The simplest and cheapest way to go for me would be to buy the groupset and replace only the non-boost chainring (6 mm offset) with a boost variant (3 mm offset), while keeping the rest of the crankset. Would this work?
I.ve alredy have a boost hubs, and a non boost entire crankset. At the end of the fist month the chain touch the frame, then I realized before but on race confirmed a noisy chain, and finally with some misshift twice. Exactly what ive been searching for 3weeks now, and i found that as Sram and one up moves the just chainring, and shimano offer change the cranckarms. The entire boost system has to be used with all the pieces togheter to have a proper chainline 53 mm to my taste.
