3x very low use Shimano CS 7700 Dura ace titanium 11-23 cass

[Grease Monkey]

3 cassettes removed from two pairs of very low use time trial wheels (one was a spare) These are scarce now and the only reliable UK source is here: http://www.bikeplus.co.uk/p/24765/Shima ... tAodpTcAmA

At £113 each. The 11-23 is nearly always out of stock. They estimate no UK stock left at all after June 2014.

Selling at £65 each for the two with alloy locking ring, and £60 for the one with HG 50 lock ring . All pretty much perfect. 158gr each!

Here are the specs for the uninitiated:

Four largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity

Largest sprockets are made exclusively from titanium to reduce weight without sacrificing strength.

Sprockets are extensively cut away and drilled to further reduce weight without reducing rigidity

Nickel-plated finish offers hard wearing resistance to corrosion

For Super Narrow 9-speed HG chains
Weight: 160 grams for 12 - 23T

The first pic shows pretty much the very low use of these sprockets. All off the same Triathlon/TT bike, they haven't covered more than 200 miles between the three of them.
