Shadow ders and Tiagra 9spd STI shifters
Any reason why these 2 wouldn't work?
Currently have a stock Vaya build with Tiagra 9spd STIs and a Long Cage Deore LX der. Would either an XT or XTR Shadow der work with the Tiagra brifters?
Don't see any reason why not. On my vaya I use an xt m770 RD and dura ace 9sp bar end shifters. They work perfectly. With brifters you'd probably want to stick to top normal to avoid confusion.
If you don't already have the RD though there is no reason to get a shadow model (lighter maybe?). Isn't the whole idea of the shadow just to give better clearance on suspension frames?
