4600 is 10 speedJust reading this ...... I know I've been in contact on another forum, but Tiagra 4600 is 9 speed. Tiagra only became 10 speed with 4700 and these have a different pull ratio to other 10 speed kit, so probably not what you need
If you intend to keep your existing stuff, you are restricted to 5600, 5700, 6600, 6700
Edit and DA 7800 & 7900
Well, blow me, just done a search and it looks as though there is a 10 speed 4600 as well as the 9 speed version. Apologies4600 is 10 speed
Thanks for letting us know. That little detail has eluded me. As if Shimano hadn’t made things complicated enough!Well, blow me, just done a search and it looks as though there is a 10 speed 4600 as well as the 9 speed version. Apologies
There is no 9-speed version of 4600. 10-speed Tiagra 4600 superseded 9-speed Tiagra 4500 in 2011/12.Thanks for letting us know. That little detail has eluded me. As if Shimano hadn’t made things complicated enough!![]()
I'll bow to your expertise. The official Shimano site didn't mention the number of gears, I looked at some forum discussion.There is no 9-speed version of 4600. 10-speed Tiagra 4600 superseded 9-speed Tiagra 4500 in 2011/12.
Swap this for some shifters.I'll bow to your expertise. The official Shimano site didn't mention the number of gears, I looked at some forum discussion.
I'll leave it there, I'm already about to hire a JCB to dig myself out
