Have the 9 speed Tiagra on my 2011 Oppy A4 which I bought new specifically to go on the TACX Bushido Ergotrainer (so it have never been ridden on the road and gotten grimy), and whilst the levers are not as comfortable as my Campys the changes are certainly decent. I think if you had the Tiagra you would certainly not be disappointed - my only issue is dropping down a gear instead of up the first time I change gears (and sometimes the next couple as well if I ain't had enough coffee).Stuey wrote:That's interesting, and strange. It'd be so easy for Shimano to copy the pivot position, given the performance advantage. I guess they still sell enough!
Can't comment on the Tiagra brake performance as have not used them in anger.
