3. How to Measure a Mountain Bike Frame: Embrace Your Inner Handyman (or Handywoman)!

Whether you’re on the hunt for a new MTB, or you’re just plain curious about your current two-wheeled steed, understanding how to measure a mountain bike frame is a skill worth having. Let’s break it down:

  1. Ensure your bike stands proudly on a flat surface.
  2. Your eyes should spot the crank (where your trusty pedals attach) and then drift upwards to the top of the seat tube (the home for your seat post).
  3. With measuring tape in hand, gauge the distance between the centre of the crank and the top of the seat tube. And there you have it – your frame size in glorious cm or inches!

A word to the wise: if something feels amiss with your bike frame, trust your instincts. Your body knows best.

4. Mountain Bike Size Up or Down? The Ever-Present In-between Sizes Conundrum

Hovering between two sizes is a bit like being caught between a rock and a hard place – or in this case, a small frame and a slightly larger one. Do you mountain bike size up or down? Here’s a tad more insight:

  • Size Down: Picture yourself weaving through technical terrains, favouring tighter control, and savouring a nimble feel. If this sounds like you, perhaps consider sizing down. Smaller frames tend to offer that bit of extra manoeuvrability.
  • Size Up: Dream of seamless stability, especially during those exhilarating descents? Or perhaps you’ve been blessed with a longer torso? Going up a size might be your golden ticket.

Remember, at the end of the day, it’s all about how you feel. When in doubt, trust your gut (and yes, your bum).
