What's going on with this derailleur-crank combo? They interfere

[Ugo51]

Hello everyone,

A few months ago I got myself an Orbit Harrier. It sat around for a while, until yesterday I had the time to replace the parts that needed replacing (which was most of them, turns out...).
Among them, I swapped the groupset with a (partial) 6500 triple which I paired with a Sugino VP crankset. Looks great, but when switching to the outer chainring, the derailleur interferes with the crank arm. How is that possible?
And in this photo I already have the derailleur one click inwards compared to what it actually takes to switch up to the outer ring. I still have to fine tune the position of the derailleur, sure, but having never had this problem before I was wondering if there is something else I'm not seeing.
Thank you!

Front mech looks too wide, my old narrow front mechs from the 80’s would do the job though

Afaik more modern front mechs for compact chain sets and a wide 10 + speed cassette at the back might not be compatible with your chainset ?

The cage is too wide you mean?

in fifty-five year o' cycle spanner twistin' have only had this difficulty come up once

the machine was a 1959 Cinelli Super Course assembled by noneother than Spence Wolf himself of the Cupertino Bike Shop in Cupertino California

its chainset a Cinelli-Magistroni thing-a-ma-bob with T.A. chainwheels
the front mech was an all-metal Juy L.J. 23 pushrod chappie contemporaneous with frame

everything cleared


[brochure page of 1960]

cycle's owner requested fitment of a Campag Record front mech

we ran into this same snag so back on the bike went Monsieur Lucien...problem solved

have ofttimes thought we should have an accepted term in the trade for this clearance measurement much like we have "Q-factor" for the overall width of a chainset

That happened to me recently. I rotated the front mech round slightly and that sorted it.

The Sugino crank might sit further out than the Ultegra front derailleur was designed for. Try measuring the chainline and compare with Shimano specs
