Hi calla ~

I checked out the Dolce Sport online, and it has standard Shimano STI shifters (aka "brifters" because the breaks and shifters are integrated). This type of shifters are pretty much standard on all new stock road bikes these days. I suppose there are a few that use Campagnolo Ergo-power shifters, but Shimano definitely has the lion's share of the market here in the USA. You'll love 'em once you get used to them - and it won't take long!

Downtube shifters and bar-end shifters ("barcons") are older methods for road bikes and still have their afficionados.

I have a variety of shifters on my three bikes: STI on my Terry, Campy on my Aegis (which I had built up from the frame), and barcons on my Bike Friday touring bike (so I could use V-brakes and fatter tires more effectively). They are all very easy to use - but changing back and forth between all the different methods can get a bit confusing at times!

Hope you can get the bike you want!
