JohnTM, when you say STI shifters, are you talking about those that you nudge inwards towards the centreline of the bike to change gear? (excuse my ignorance on th e terminology). Also, what was your old bike? A hybrid?
STi (I think it stands for Shimano Total Integration, so it's not really a generic term) basically means shifters integrated into the brake levers. Sora uses the brake lever to shift to larger chainrings/sprockets and a thumb lever (that you can't reach from the drops

) to change to smaller. Tiagra and onwards uses the brake lever and a "paddle" type switch on the inside of the lever in the same way.
My old bike was a 2nd hand £50 road bike I bought to see whether I liked drops and skinny tyres (do I ever

) Nice old bike, steel frame with bags of character in the ride, but downtube friction shifters, and heavy compared to the SCR. Prior to that I rode a hybrid (Raleigh Pioneer Elite) that I still use for nipping to the shops etc
As much as I love my Sirrus, I'd love to get a road bike some time in the future.
Well worth trying - I wouldn't go back to a hybrid for covering distance, I think, although the riding position etc of a drop bar bike isn't for everyone.
