Hello everyone,
I bought a fischer viator 2.0 about a year ago and since I really enjoy riding my bike I was thinking about potential upgrades.
Since my viator is the version that has NUTT brakes I was thinking about upgrading them and maybe the wheels?
Do you guys have any other suggestions or do you think I should skip upgrades on this bike and safe the money for a potential better bike in the future (wont be the near future probably)
Thankful for any input.
