I have a touring bike with road shifters. My front Tiagra shifter is starting to skip at particular areas and the mechanic advices me to look for a new one. After a bunch of googles ended up getting a good idea on a pair of 105 shifters. I just got them installed yesterday.
With new shifters and new handlebar wrap, it justs feels like a new bike. It seems very smooth. So happens they put the same colour as the original wraps so it actually brought me back to the point in time when the bike is new and I was so happy!
So do yourself a favour, spend a little money on handlebar wrap and you can make a 5 -year old bike brand new again.
