The front mech appears to be non-functional already, despite that bike only having done around 4k miles at most since then. The problem seems to be that the spring to return the front mech back to the inner ring is just not pulling any more, and I have to get off and push it with my (dodgy) thumbs to try to move to the inner ring. Rather annoying.</p> <p>I've given it a good clean with water, then tried GT85 and WD40 to loosen it up, to no avail, this thing seems to be done.</p> <p>Is that lifespan for a Tiagra front mech normal? </p>
