Rated 2 out of 5 by I have had nothing but trouble with my pair. The RH one kept breaking cables every 3 -4 months, always at the same spot just inside the shifter. One time the cylinder end broke off and fell down inside the housing so I had to partially dismantle it to get the end out. After only 3 years the locking tabs of one of the sprockets snapped so I had to replace the whole lever. Luckily Chain Reaction sell them individually because Shimano will only sell them as a pair. 24 August 2012
Rated 1 out of 5 by After just 1000 miles on my road bike the left-hand shifter has broken, leaving me with a £250 bill on an £800 bike. Despite hunting I could not find an individual shifter so had to buy the pair. Then there is the compatibility issues with the different models of what is essentially the same thing. The hassle I have had with this would normally have made me reconsider my choice of drive train if it had not been for the fact I have been using shimano for 15 years on 5 different bikes. 07 May 2011
Rated 4 out of 5 by I am a very active road rider with an ambition to ride outdoors even in the coldest winter. On my two summer bikes I have Shimano Ultegra 6600. My winter bike is a former hybrid with race bike dimensions. I switched the straight bar to a road bar, the V-brakes to cantilevers and the triple chainset to a compact double. My choice of groupset was Shimano Tiagra (except for the Altus brakes). Everything has worked very good this winter and I can hardly tell the difference in performance between my Ultegras and the Tiagra shifters. OK, it's 9 instead of 10 gears and just a little bit less smooth but the function is great. 23 February 2011
Rated 5 out of 5 by These were fitted to my Scott Speedster bike when I bought it and I've riden alot of miles (over 6000 miles in first year) with them all through winter (every day) and done nothing to maintain them (no oil no grease) and they work perfectly still. 23 November 2009
Rated 5 out of 5 by For the price point, these shifters are great. Easy to set up and I've ridden over 1000 Km with them through hilly terrain, shifting constantly. Also used them on the bike/trainer (Spinerval interval training)this past winter with no problems. They have stood up very well and provide very smooth shifts, even mated to worn components. 26 July 2009
Rated 2 out of 5 by i've now broken 2 sets in 8 months - these are clearly made of cheese. avoid if possible. before they break, they're ok. 12 June 2009
Rated 5 out of 5 by I got the Tiagra 4500 shifters to replace old Shimano 105 (9 speed) shifters on my training bike. The Tiagra shifters seem slightly bulkier than the 105's but the hood area is a bit narrower making them easy to grip. The shifting is positive and the design feels solid. I like the gear-display that gives an idea of which gear you are in (helpful at night). The kit also included gear-cable inners and extra spacers to adjust the reach of the levers. 04 November 2008
