Scott Scale SL

I thought that MTB are not meant to be light because of the heavy duty work they do in the mountains and would typically be in the order o 13 to 20 kg.   Big tires, big frame, big cogs and heavy duty BB and axle.    However, MTB can be made as light or lighter than road bikes.

Here you can see an MTB that tips the scales at 6.54 kg or about l4 lbs.  My Fuji road bike would be 16 lbs.   Light Scott MTB

Making your mountain bike lighter  from From Wikihow

Some how to:

1.  Consider lighter frames:   carbon fiber, titanium, aluminium in that order

2.  Switch to lighter wheel set

3.  Remove the third chain wheel and have extra large cogs

4.  Switch to ligher tires.  Some tires can weigh as much as 900 grams. Some tires tip the scales at 300 grams and you save 1.2 kg on tires alone

4.  Remove all unneccesary accessory that add weight

5.  Switch to ligher pedals say carbon fiber.   My pedal at road bike is mere 88 grams for the pair.  Other pedals are about 400 grams for a pair

Cannondale FSi weighs mere 18.6 lbs but cost $4,500

4 ways to lighten your bike

1.  Lighter tires

2. Go tubeless

3.  Reduce body weight

4.  Lighter used fork
