Why is Shimano taking so long to roll out 1x for CX/gravel/road?
There's clear demand for it, the number of people running DIY 1x setups. I'd certainly adopt 1x on my TT bike and a CX bike (when I get one!).
There's the usual rubbish about the gear range being too small, the gear jumps too big and the chain line not being optimal - but these really have no effect when you consider how they are used.
My TT bike, for example, I only ever use the 52t big ring with an 11-28 (ok, I used the little rin when I was rolling round a car park waiting for my mates to arrive), a wide range of gearing isn't needed, so losing the lower gears doesn't matter. Conversely, for a CX bike (when I had one), I was rarely topping 30mph (and when I did it was usually downhill on a road getting to or from some CX terrain) - so any gearing allowing you to go above 35mph can be dropped - the resulting gear jumps can be kept more or less the same as a 2x setup.
And don't for a minute think I'm suggesting doing away with 2x setups completely - definitely not! I have 52/36 11-28 on my Canyon and I use every gear pretty much every ride, means I can comfortably cycle between speeds of 6mph to 45mph without grinding or spinning too much. Similarly, the 50/34 11-32 on my Whyte is great for endurance riding and commuting, where speeds tend to be a little lower (gives me a range of 5 mph to 43 mph).
Am I alone in wishing Shimano would bring 1x to CX/road? For now, the Wolftooth conversion will suffice my planned CX build (and maybe my TT bike!).
