Following a recent crash, I am going to need to replace the tiagra double 9spd shifters on my road bike. I am trying to decide over the following options:
1 - simply replace the tiagras
2 - change to 105 shifters - will probably need to change the cassette at next service anyway (thinking of a 12-27 instead of 12-25 for the Lakeland hills), but will a 10sp cassette fit on in place of 9spd?
What are the benefits of 105 over tiagra apart from slightly lighter weight (which I could easily lose myself) and routed cables?
Thoughts?
rear mech 105; front mech tiagra; c/set truvativ elite compact 50-36

105 is better shifting, although I've not tuned it right yet so can't notice the difference yet.
You can use 10 speed shifters with a 9 cassette, as long as you set the limit screws right. I don't think you can do it the other way round.
With 105 you have 10 speed compatability which means you can mix and match with the groupsets above if needed, see bargains etc. The shifting is a lot sweeter and a bit more positive under load. The cassette probably will depending on the hubs, but as said 105 levers will work fine with your set up, and the best upgrade you can make to any production bike will be with the wheelset so going this way helps futre proof a move in this direction.
105 (5700 black) shifters
105 (5700) cassette 12-27
105 (5701) chain
These would need to work with my existing components
105 rear mech - not sure if 5500 or 5600
tiagra 9 speed front mech
truvativ elita 50 -36 chainset
Would these above components work well?
