105 Front Derailleur with Tiagra Groupset

[BenTheDesigner]

Hi,

I'm looking to replace my front derailleur and was wondering if I'll be running into problems using a 105 10sp (5600) with my current Tiagra 9sp (4500) groupset. I know the 10sp chains are slightly narrower but expect there will still be clearance. I'm unsure what "Applicable chain line" means, as the 2 derailleurs vary - Tiagra 43.5mm, 105 45mm.

Thanks in advance.

A 105 FD will work fine
I think the 45mm chainline is only for triple

That's great PpPete. Thanks for the info

Just to let you know, chain reaction cycles are currently selling the black brazed in version of the 105 front mech for 10.00!

Bought myself one from Chain Reaction yesterday actually. Thanks for the heads up. Ribble are selling the 5600/5650 chainsets for as little as £63.96 too! Anyone know why 105 is going down in price so much? It's cheaper for me to buy it than replace the Tiagra currently on my bike!
