@slickci. I'm glad you're enjoying your Lefty. I have 8,000km on mine and it's still going strong. I now have 5 bikes, so my Lefty doesn't get the kms that I'd like, but it's still one of my favourite rides.
i've done a lot of upgrades to mine and my favoute has to be the Ritche drop bar that I installed. For some reason the stock drop bar made my hands go numb after riding for more than 25km.
I swapped over to a flat bar, which I liked, but eventually I went back to a drop bar setup. For me, the Ritche bar is near perfect and my finger numbness has decrease substantially.
I also got rid of the stock tires after riding on them for only 3 or 4 months. I found them to be noisy and slow. I now have a pair of
Specialized 2 bliss Pros (47mm) and couldn't be happier.
They don't have the stock tire's grip, but they are way, way faster on the pavement, which is where I do most of my riding.
Where do you live in Canada? I'm on Vancouver Island.
