Hi,

I've hit a problem with my 2010 Kona Jake the Snake. The Shimano 105 (10 Speed) rear shifter is shifting really oddly - It's absolutely fine when shifting up the gears... and fine too when shifting down the gears... but as soon as I change direction, I need to click twice to get it to shift one gear (i.e. the first click in the opposite direction to "flow" does not pull/release enough cable to change the gear)

I've replaced my inners/outers and greased everything up. The rear derailleur seems fine as does the alignment. All I can think of at the moment is that the STI shifter is the problem... but I can't really do much with this.

Anyone had this experience? Guess I may need to get shifter replaced under warranty

Thanks!
