Alert I am unsure of the right terminology for gear-wheel but I mean the round things near pedals such as 3x9 or typically with 3x7 (3 front, 7 back) mix in commuting bikes.
My current gears are 3x9 (3 front, 9 back) but I plan to change to cheaper, the current gear-wheels are used (about 15k km, 4winters and 3 summer).
- Can I put other gears such as 1x7 or somehow reuse the old gears?
- What should I take into account when choosing other gear-wheels and gears?
There is nothing problem with my current ones, they work fine (a bit slower than as new but not a problem) but I cannot spend too much on upgrading the gears/gear-wheels. I need to know what to look for in second-hand stores or to find some sort of compromise i.e. perhaps to upgrade things slowly part-by-part.
