I bought a 2013 Specialized Secteur Elite with a Tiagra Groupset at the beginning of the year, from the Concept Store at Fort Dunlop in Birmingham. After a few months I noticed I could not get it to go onto the smallest sprocket (whilst on the big chainring). Sometimes the chain would eventually move if I stopped pedalling and re-started. I know about the adjustment you can make on the shifter, but this doesn't work as there is no more play. I had a bike mechanic friend of mine look at it and he thought that the gear cables crossing under the down-tube a bit strange.
Since then I've done some punting around on the internet but can't find anything specific to my bike or groupset. I'm fairly new to the modern road bike scene so I'd like to garner some opinions from the more learned readers of this forum.
Thanks in advance
