I built this specially to enter the 2019 Lake Taupo Cycle Challenge. Here in New Zealand this is the major annual cycling sport participation event. I have a few mountain bikes but nothing very suitable for a long road race. So this build was based on a Surly 4130 CroMoly, double-butted main triangle, ED coated, TIG-welded frame and Shimano GRX group set.
I have to admit I’m struggling with the drop bars on this. It’s light, very agile, quiet, and a joy to change gears. But the riding position is uncomfortable on long rides and the directional control is very uncertain almost twitchy. The bars just seem to narrow even though the width is, as recommended, the same as my shoulders.
The gear ratios are on the left, on the road I’ve never use the smaller ring on the crank.

I have since ditched the drop PLT bars and changed to a Giant Contact SL Trail Riser. To go to straight bars meant changing the brifters over to SL-RS700 flat bar road shifters to be compatible with the GRX derailleurs which have road shift pull ratios. The brake levers are now SLX BL-M7100 2-finger.
