the title says it all. strange question, no? of course the rack
struts should mount outside of the dropouts to avoid interference
with the chain.
but is there any other reason NOT to mount inside the dropouts?
i'm moving old piece parts to a new frame (BMC alpenchallenge AC01).
outside mounting is not happy. a ridge along the dropout prevents
the strut fitting on the upper eyelet. lower eyelet is too close to
the skewer to mount the rack.
i suppose i could try cutting/trimming the rack strut, or make a
triangular aluminum spacer. perhaps bending the strut to get the
approach angle different. however i'm living in a small town in china
with NOTHING. everything must be mail-ordered....tires, tubes, nuts
and bolts....everything. want to keep it simple and not make any
changes i can't unmake.
aluminum racks are generally spaced about the same as a bike frame, so
must spread the struts out a bit to mount. or in my case squeeze them
together about the same distance.
so. other than avoiding chain rub, and the fact that it's traditional....
everyone mounts a rack on the outside of the dropouts.....is there
any reason NOT to attach the struts inside the frame? the upper
eyelets are high enough to provide ample chain clearance.
