| 46 teeth. Absolutely new and unused. Possibly, some extremely minor shopwear.
In Campagnolo's famously tough, long-wearing, extra-hard aluminum alloy.
The 110mm b.c.d. pattern is one of the most popular and versatile in existence to this day, found on many other makes and models of singles, doubles, and triples, including most 'road compact' cranks by almost all makers**, Shimano older 5-arm Deore, XT, XTR, and others; Sugino Mighty Tour, Aero Tour, XD, Impel, and other MTB and 'compact' types; Suntour XC (non-microdrive) Pro, XCE, XCD, and others, Specialized touring and tandem cranksets from the 80's and 90's, some by SR, a few by Stronglight, TA, Takagi, and probably more, not mentioned here.
**(except for current Campy UT road compact models, ironically, because they have 1 odd bolt location on theirs at the mounting hole behind the crankarm.)
If you are unsure of your crankset's Bolt Circle Diameter, you can measure from the center of one chainring bolt to the center of one adjacent to it; that will be 64.7mm, if the BCD is 110mm.
This chainring is fitted with an anti-jam pin (goes behind the crankarm, to prevent chain damage caused by an overshifting front derailleur) and so is intended as an outer ring, but will also work perfectly as a single-ring, or as an inner or a middle, with the pin removed.
46 teeth with standard 1/2" pitch x 3/32" width, fits all derailleur chains from vintage to new extra-narrow ones. (Can also be run with a wider 1/8" chain if desired, and used with a 1/8" width single-speed freewheel or a fixed-cog.)
Made in Vicenza, Italy. Will be carefully packaged and shipped insured. Cheapest shipping to Canada is $17 (or $3 cheaper than the other posted International rates.)
