Looking to build a gravel/touring bike with drop bars, and after a bit of thought comparing to Shimano/SRAM the Advent X seems to be offering quite good value, given the prices from wiggle. The main appealing points for me is that the rear derailleur is a clutch RD and capable of supporting up to 48T. To get a similar offering (for drops + off road rear mech) its either GRX, Shimano road + hacks, or SRAM - with the brifters alone costing more than the full set.
Microshift cable pull ratios are not compatible with Shimano/SRAM so you will need to get the shifters & RD together.
Downsides? it is only 10 speed, and cable brakes only for brifters, but value for product wise I think its punching above its weight and has good reviews (https://www.bikeperfect.com/reviews/microshift-advent-x-drop…)
The component picks are:
microSHIFT Advent X M100A Dual Control Lever Set $96
microSHIFT Advent X RD-M6205 10 Speed Rear Derailleur $64
microSHIFT Advent X H104 10 Speed Cassette $27
Or the G104 cassette thats 100g lighter for $54
If you want to go flat bar shifters, it is only $19
nice bundle
