Good replacement shifters.

Excellent replacement/upgrade shifters. These are at the lower end of Shimano's range but would definitely be an upgrade to the twist shifters or brake/gear shifter combinations. Nice smooth up/down changes together with the benefit of the the 3-gear multiple shift down facility on the right hand shifter - very useful for those sudden hills! I'm using them on an old 21-speed MTB, as opposed to a 24-speed as it was a lot cheaper for me to get this set than the correct 21-speed set - note left hand shifter is identical, just make sure for the 8-speed right hand shifter that your derailleur limits are set correctly at the back. The included cables work fine although I cannot tell whether they are galvanised or the better stainless steel variety.
