A couple of years ago I bought a rather cheap racing bike after my mountain bike was stolen. I didn't use it much at first. Now, with corona I spent a lot of time on my bike and probably did around 1000-1500 miles in the last 3 months.
What do I need:
Now the chain isn't that stable anymore and I guess I need new chainwheels. I went to a forum and asked about details on how to measure the size to replace them. The users were mostly amused/shocked about how used my chainwheels look but did not really answer my question. There was one good suggestion to directly invest in a crankset, which makes sense.
What do I need it for:
Like I said my bike was rather cheap ~315 pounds (https://www.decathlon.at/rennrad-triban-500-rot-id_8377759.html). But I am perfectly happy with it, since I can do my daytrips of 20-60 miles or multiday trips 250-400 miles and I don't care much if my bike is 2 pounds more or 10% slower.
First I spent quite some time researching chainwheels and how to replace them. But I am also fine, changing the whole crankset (if they include new chainwheels :)). I found that cranksets are much cheaper for mountain bikes than for road bikes. Might be due to the weight but I also read that MTB cranksets might also be used on road bikes, so I am not sure.
The price range seems to be insane, like 20 - 1000 Pounds and more. I prefer a lower price but am aware that the quality should be good enough that the material does not break too fast.
- Quality Brands:
My research indicated that Shimano has good quality material. But still there also seems to be a wide price range for them
- Cheap alternatives:
If I may add a few examples:
That price range makes perfect sense for my current bike, from my current perspective.
Are there arguments for not using one of these for my bike if I plan to ride around 1-3k miles the next years?
Concerning doubts that I require new chainwheels. Please don't laugh too hard, Biking just started as a corona-replacement hobby and escalated quickly ;)
