    Shimano R440 VS R660 Shifters

    I know these are technically road shifters but they go on a flatbar. What's the difference betwixt these 2 sets of 9 speed shifters?

    The R440 is a Tiagra level shifter...Tiagra is the road version of Deore. The R660 are Ultegra level, which is the road version of XT. So basically it's a matter of the quality of parts...the R660 should be a little more durable and have a little smoother action.
