12 speed may be coming

The cunning Taiwanese have developed a complete 12-speed derailleur system and a couple of cassette combinations. The new components are shown in the KCNC 2012 catalogue released for download, and KCNC is a company with a track record and established worldwide distribution. KCNC make some good kit using machined aluminium and titanium alloys, with cassettes, cranksets, jockey wheels, stems and seat posts.

There are two 12-speed cassettes listed:

11-25t 11-12-13-14-15-16-17-18-19-21-23-25
11-30t 11-12-13-14-15-16-17-19-21-23-26-30

All twelve sprockets are individually machined from titanium, according to the KCNC catalogue, and mounted on an aluminium carrier. There is no chain mentioned in the catalogue so when KCNC eventually recommend a chain it could be an existing narrow model or they may be working in partnership with a chain maker for an even narrower one

Just in time for the 'boys in blue' who will be riding up Tourmalet in July 2012. Put that on a triple and you'll be spinning along at a cadence of around 110 all the way up the climb. - Junaid

Well a sprocket 11-23 works both up and down..;-) That would give a cadence around 7 1/2- 10 going up
