I'm looking for a more comfortable flat bar for my new 29er, but being new to 29ers, I'm not sure what's out there for 'em (& last time I rode with a flat bar was in the 1990's
)
The current flat bar & stem are OK for height, but the bar doesn't have much backsweep (5 degree I think) - not bad when off-road and stood on pedals, but pretty uncomfortable on the longer seated sections of rides.
I prefer aluminium bars and am not bothered about the brand (wouldn't rule out carbon if there are any super bargains about). Any sensible suggestions appreciated. TIA.
