Hello, I currently have a Shimano 10-speed derailleur. Could I replace it with the Envolio automatic hub?
If you want to paint over scratches in a bicycle frame, apply a clear coat, then a clear coat, and so on. But when do you need to apply primer, or do you even need to apply primer first? Or is it possible to do without?
Hello, For my birthday, I wanted to buy a gravel bike, but I've come to the realization that all entry-level gravel bikes (€1200-1600) with aluminum frames only have a carbon fork… My father isn't sure about it, as he considers carbon to be unstable… I've read up on it a bit, but I still don't…
Hello folks! I'd like to buy a used bike for up to €200 that won't let me down easily. The frame size would need to be around 46 cm (if you're interested). I'll probably be using it pretty roughly, riding through mud and over bumps (without wanting to feel every single bump deep in my…
A few days ago, oil got on the rear brake disc of my bicycle when I tried to oil the chain. It's been a few days now, and I've already used brake cleaner. The braking effect is still very weak. What else can I do?
Question to all motorcycle fans: Do you prefer MotoGP or World Superbike? I think both have their advantages and disadvantages, so it's hard for me to decide.

Carbon cannot be permanently deformed. Even if a deformation is so strong that the inner layer structure is damaged, it springs back into its original shape. A lasting deformation due to destruction would clearly be recognized by cracks and fracture edges. And apart from that, this is not a very heavily loaded place at the frame.
Whereas a small cavity at the place may have been absolutely necessary, because someone has noticed in practice that the space between the bottle holder thread and the pipe bend is not enough for a bottle holder, but you did not want to make the ( expensive!) negative shape for the frame completely new. At the place a little material is applied into the negative shape, nicely ground, gives a little more space for the bottle holder without needing a new shape.
