It is a bit niche but for all the cyclists out there on ozbargain this is a really cheap way of getting into the world of wireless shifting for a fraction of the price.
RRP prior to this is $2499 with next to no installation it's a reliable user friendly install.(note no cranks or brakes are included)
Hydraulic Upgrade kit also available for $1899 down from $3399
If you're in WA give Bikebug Perth a call or email and order through them, just looks after the store a bit better.
*EDIT: This is a 12 speed groupset and unfortunately not backwards compatible with 11 speed due to smaller cassette spacing. (almost too many shift options now)
