Does this come from the same school of thought that says disc brakes are pointless on the road?
No, it comes from the school of thought that says a more upright position is safer than using drops, in busy urban areas, and that mtb bars offer better control.
Every time I commute on an MTB, I get annoyed that I can’t filter through small gaps any more, or have more than one comfortable hand position. getting down out of the wind is also more difficult. ‘Control’ seems much the same, as its just riding along the road, rather than doing wkkd sik gnarr.
One, you’re not meant to ‘filter’ through small gaps in traffic, as it’s bloody stupid and dangerous, and two, you could use bar ends or something to give you more hand positions. I’m talking about urban riding of all kinds here, not just commuting along an A-road in berkshire or whatever. And hang on, ooh, who might be an expert in urban cycling, having done it all their life and cycled extensively in urban areas? Oh, that would be me then!
So you are wrong.
Wide risers/flats suck on road. FACT
And you are even wronger now.
