Looking for information on components to do a straight bar conversion for an extra road bike that I have. The bike has a 105 rear. Shimano's web page lists shifters and brake levers for straight bar conversions, any other resources? I have an extra set of MTB shifters (deore) but have no idea if they would work with the 105. Any suggestions would be helpful. looking to do this as cheaply as possible. Thanks in advance.
