Thanks!
A 74mm BCD (standard) 26 ring costs much less than a new cassette
you get tighter spacing on the smaller casette (13-29 lacks an 18 cog) and/or perhaps delay the shift to the big ring
Campagnolo branded cassettes have synchronized shift gates and ramps for almost instant and silent shifting
as a tangent if you do want a new Cassette, order it from the UK.
Ribble has galvanized Veloce cassettes including the 13-29 for $42.61 not including the current 10% off sale.
Nickel-chrome Centaur cassettes are $57 for 13-26, $89 for 13-29, and $92 for 12-30.
