Sora gear shifting.

Just bought a road bike second hand with the Sora groupset. Had a wee scoot about and it seemed to me, a moutain biker, that the gears may not be indexed properly.
However, I got to thinking that it might not be as intuitive or easy as using MTB trigger shifters. For instance I was struggling to get it to catch onto the large front cog, is there an optimum back deraillieur position to get onto the big cog or should it shoot up in any gear?
Hope someone understands.

Any gear should be fine but if your in the larger cogs at the back it might be a bit slower shifting up at the front.
To shift onto the big ring on the front you may need to push and hold the lever a little until it moves up.0 -
Hmmmmm was holding it in, just wouldnt make the final jump. Will have a longer ride tomorrow see whats what. Might just throw in and get it indexed but the lad said it had just been serviced. :roll:0

it's quite easy to adjust, for sora you'll find all the info needed here...

the best thing i would suggest is to keep your chain in as straight-a-line as possible ie big and little/little and big if that makes sense, this should also pro-long the life of your chain and cassette this will also stop most of the rubbing noise people get on the front mech, but yeh set-up is the first key thing0

What's the back derailleur to do with shifting at the front? Set up the front derailleur using the cable control at the side of the shifter. If it doesn't reach up and onto the big ring, adjust the H screw on the derailleur. Pull the gear wire tight so that the derailleur is out as far as it will go.Then experiment with the H screw to set the limit - clockwise will move it in, anti-clockwise will move it out. One you've done that you can check the chainline runs true and straight from the smaller cogs at the back.0

Are you pushing the lever all the way across? It has a double-push movement, which allows a part movement, for trimming.0

Moving from mtb to road myself, and having Sora as my first groupset, it is hard to shift from middle to top chainring when on the top three cogs, any other it was fine, chainline seems to play quite an issue.
It also probably depends on what gruppo your used to on mountain bikes.
My new SRAM will shift to both chainrings on all cassette positions but is nowhere near as easy and smooth as a XT, LX, SRAM cassette setup on my mtb.
You runnin triple or double/compact chainrings?0
