this may seem like a dumb question; i geezer my age should know, but i'm faced with
a dilemna. i just lucked into an '88 5spd raleigh mixte, (according to the yr. code on the
derailleur). i've been on mtn. bikes for the 30 yrs. my problem is this, the mixte, which
incidently has never been ridden, has 27'x1.25 tires. i have plenty of clearance; can i
put 700 x 1.5" tires on those rims? the derailleur works so flawlessly with the cassette
as it is that i hate the thought of changing it out for different rims, but i really want at least 1.5s to tour. can't seem to find 27s in any size other than 1.25.
