I have talked about it before, but another thing that I have really loved in 2009 is the KCNC products. KCNC is a company based in Taiwan that makes lightweight, high performance components at a reasonable price. There are many ultralight race components that I lust after but have mega high price tags - KCNC matches the weight and performance but yet is at an affordable price. In addition, to this day, I'm still to have a single issue with any of the products - I have used the seatposts, bars, bar ends, skewers, stems, cassettes and jockey wheels in some form for the last 3 years.
For me, of the products I have used, the seatpost is the star of the show - for £75 and 150 grams you get a set and forget way of dropping 100 grams off most posts. I have used the post on all my mountain bikes, my road bike and my cross bike.
