Hi, I’d like to start by saying I’m pretty new to road bikes, but have used a MTB for commuting, and I’m used to doing the basics such as cable changes, indexing and adjustment.
I’ve recently picked up a 2nd hand Specialized Allez sport, I think the 2011 version. I decided switch the shifters from the sora 3400 to 3500, as I didn’t like the thumb levers. Grabbed some 3500 shifters off eBay, and I’m having trouble with the front shifting.
Going up, it clicks once and the mech moves a little to the right, but not changing the gear, if I push it in again, the mech moves enough to shift into the top ring, but there is no click, and letting go of the lever the mech moves back again and it drops into the lower ring. I’m confident it’s not too much cable tension, as it won’t ‘click’ even with very low, or no tension at all on the cable.
Is there something I’m missing? Or is it likely a problem with the shifter itself?
Any help much appreciated.
ps tried to add videos, but I’m not allowed to post links. Anyway I could embed them or something? Been a while since I did any sort of code work.
