All Bike Parts FAQs
How do I check if a replacement part is compatible?
The easiest way is to check the details already on your bike. Things like tyre size, wheel size or model numbers can save a lot of guesswork. If you're ever unsure, comparing the old part with the new one usually points you in the right direction.
Do bike parts vary by wheel size or frame type?
They do. A part that works perfectly on one bike might not fit another, even if they look similar at first glance. Wheel size and frame design can make a bigger difference than many riders expect.
How do I choose the right bike tyre?
Think about where you ride most. If you're mainly on roads, a smoother tyre tends to roll better. For trails, something with a bit more grip usually feels more confident. Most riders end up choosing tyres based on the type of riding they do week in, week out.
