Bike Radar reports that Campagnolo is going to announce an 11-speed cassette for three of their 2009 gruppos. The 11 cogs in new 2009 Campy 11-speed group set cassette will fit into the existing space that currently accommodates 10 cogs. So, as pointed out in a Bike Radar article, the 2009 chains and chain rings may require spot-on drive train spacing in order to accommodate the narrower gaps between cogs. You bike mechanics better find some inner peace or a vat of coffee, since the shifting and derailleur adjustments for 11 in the back and two up front, coupled with the new 5.5 mm chain, may teach you something about yourself. The 11-speed cassette is expected to be backward compatible with 8-, 9-, and 10-speed freehubs.
