Shimano Tiagra STI Shifters
Quality is good - not as polished as it's more expensive cousins - but sturdy and reliable.
are Shimano's cheapest 10 speed road bike offering (9 speed up till 2012) and are great value for money, sharing similar internals to some of the more expensive Shimano gear shifters!
They brake and shift gear with less effort than Shimano Sora, feel nearly as good as 105 and are only about 100g heavier than Dura Ace.
They are suitable for use with either double or triple chainwheels.
