This group has helped in the past, so...
I have a Soma Fabrications Double Cross 56cm (a steel frame cyclocross style
bike) that I use for fitness and commuting. It uses a Winwood carbon cross
fork, Mavic Askium wheels, with Cane Creek SCX-5 cantilever/cross brakes.
Right now it has black Kool-Stop pads. I originally choose the cross style
brakes and/or bike so I could run fatter tires -- lots of great rails to
trails in Wisconsin I don't need huge mud clearance -- not a real cross
rider.
Under moderate to hard front braking, the front end of the bike "shudders"
and vibrates a lot -- enough to make me back off the brake IMMEDIATELY when
it happens. The vibration seems to come in the front to back (as opposed to
the side to side) direction, like the front brake is grabbing and releasing,
grabbing and releasing.
I had the LBS guy who built the bike (and who sure seems to be a good
mechanic) take a couple of looks at it. He is an experienced cross rider
and says he has seen similar issues before. He tried different brake pads
(black vs. salmon) and slightly different toe-in settings, but it didn't
really change much.
I originally choose the cross style brakes so I could run fatter tires --
lots of rails to trails in Wisconsin Any insight into alternative things
to try would be greatly appreciated -- different brakes, forks, whatever. I
googled the issue, and found one similar complaint from a Winwood user --
not a lot of information besides that.
Thanks for all help,
Matt
