Mine is on the way to becoming a full commuter. I also have a light now (not in the picture). I would like to change tires though - the current stock ones are 860 grams each. I could easily drop 1 kg by spending about $60 - but before I do that I plan to change the pedals - a kind BF member donated hybrid pedals - I just need to buy tools to change the pedals, and the shoes themselves.
So three changes planned, as and when I can put money together:
1. Change pedals, get SPD shoes
2. Change tires
3. Switch to trekking handlebar for longer runs. Bar ends are an option, but it looks like a trekking bar is really way more bang for the buck.
