OK, glad it's sorted.

Ah so not everyone has STi levers on their road bikesI am glad as the bike I am waiting to take delivery of has thumb shifters on the flat part of the bars.
Sora is STi - just configured differently to Tiagra et al.
On Sora (and 2300) the large lever in front is a combined brake & shift to bigger cog lever. Downshifting (in terms of cog size) is carried out by the use of a thumb lever at the side of the hoods.
Campag's Ergo system places this where it can be operated from drops or hoods. Unless it's been changed since I last used it, Shimano's versions do not (possibly to avoid action by Campag, as they came up with the design first, iirc) unless you have pretty long, flexible thumbs.
On Tiagra and "upwards" the downshift is accomplished by a lever behind the large lever. It's easily operated from hoods or drops.

Maybe you were THINKING it?
/hard stare.
I think Shimano say the lever position doesn't matter on 2300 & Sora, because people using these groups will be riding on the hoods most of the time.

I think mine is different again. It looks as though the shifters are on the flats (almost as though it has had a downtube shifter conversion). Still at the price I can't complain

Perhaps it was a misrepresentation of the opinion but in the Braking from the hoods thread, in answer to a question comparing Shimano STI and Campag Ergo, the reply I quoted previously was given as advice.

Angelfishsolo, they sound like friction shifters which were very popular before indexed shifters were around.

I once had a bike with shimano 2300 shifters and the thumb lever was frustrating, you could only shift up from the hoods, and shift down on the drops, very frustrating. I now use 9 speed tiagra and 10 speed 105 from the drops quite happily.

This is what I thought but the advert states "This Giro D'Italai lightweight Aluminium Race Bike has a Shimano 14 speed index gearing system". Oh well I shall find out soon enough

They will be indexed it is just that the shifter is on the tops , i have seen them about , not to my taste personally as your hands will be away from the hoods /brakes when changing but they will do the job.

Front is friction, rear indexed. Not ideal I agree but I will get used to them I am sure. What is the possibility of upgrading to integrated brake / shifters?

I think i answered that on your piccie thread , unless you go second hand off ebay you will not get sti for a 14 speed i think, could be cheaper to buy a second hand bike than to upgrade the bike to a better spec.
You can pick up a 16 speed sti bike for what £150 second hand?

Yes it is answered now. I did look for second hand but I lost out on the ones I places bids on. As I am quite impatient I found this bike on a buy it now and went for it.

SIS = Shimano Index System - Gear shifters click when selecting, been around since the 80s (Had them on my MTB in 1989) Had them on downtube shifters on my Claud Butler 1990s road bike. Still around today with the A050 7 Speed Road Bar Shifter here:
http://techdocs.shim...69830609201.pdf
STI = Shimano Total Integration - Shift Levers and Brake Levers integrated into one unit. Tiagra and above have a paddle behind the main lever for shifting to smaller cogs, the brake lever pivots to shift to larger cogs. Sora and below use a small lever on the hoods to shift to smaller cogs.
7 Speed systems may still use a screw fit freewheel cassette on the rear, not a freehub like the 8 speed stuff, they're cheaper, but require a different tool to remove.
