A couple of quick questions from a newbie (Clydesdale) at bike mechanics. I purchased a European budget city bike a few months back to start commuting to work (actually to see if I could pull it off). After three months, and close to 500 km of cycling, I've decided to upgrade some of the questionable components on an otherwise fine bike (see pic below).
1st question- The bike has stock factory v-brakes which aren't too shabby, but for safety's sake, I wish to upgrade them to something better (quality-wise); preferably Shimano brand. Can someone suggest a compatible set of v-brakes and brake levers; or inform me if the following are compatible with each other (found them on a Greek site):
Shimano Deore V-Brakes BR-590 (set)
Shimano Deore Brake Levers BL-M590
2nd question- The bike came with a stock Shimano 6-speed setup (14-28) which doesn't cover my needs. After looking around the local web shops, I found a 8-speed cassette (11-32) which seems ideal (Shimano CS-HG 30-8). Can anyone suggest something similar and all the required hardware (derailleur, gear shifter, etc) so I can swap out my current gears?
3rd and last question- Can you please recommend anything else that might need swapping out? (putting tires/rims and accessories aside which seem to be good quality)
Thanks for all the help so far, and I hope I haven't taken up too much space and time on this forum!
