I think sloped grips are better.
I finally got tired of numb hands , on straight and almost straight bars on my '89 Raleigh and this
Specialized Crossroads. This is my upsidedown '74 Raleigh HB. ( rightside up was too high on this frame). Yesterday I rode about 20 city miles and 61 country miles. My hands felt so good. I tried gloves , but they were tight and numbing also. Bike weighed 41 lbs here. Avg. was 11.89 mph, including a town tour.
3 LBSs couldn't help with the different 22.2 mm mount , so i used a sanded copper drain pipe and PL construction glue. I have no garage or blow torch etc. I chopped the carrier also because i bought it the year before they were designed for disk brakes.
I found out where the CFers go to play. haha
