i have a old schwinn aluminum 564 with downtube shifters and a 7 speed hub in the back. i want to upgrade to brifters, but i have read that brifters are not made for 7 speed cassettes (is this true??). i do realize that i will have to get downtube cable stops, but what are my options in terms of the levers?
also a side question… i have a really old 70’s schwinn traveller i want to build up as a very light touring rig… it does not have downtube bosses or cable routing for gears, it originally had stem shifters. my question is what would i have to do to put either brifters or bar end shifters on this frame? in b4 dont waste money on shitty frame
