Making my Mountain Bike lighter — Part 2
In part 1 we moved to 1 by setup and upgraded to a Carbon fiber saddle, losing around 600 grams with just two modifications.
Tools and Spares
When I started this project I used to carry my tools in one of those tool bottles. It was a very simple and waterproof setup, however, it also meant that I could only carry one bottle with me which is a big no-no for longer rides. It wasn’t until I weighed the bottle itself when I decided to focus on what I’m carrying on the bike. The bottle with tools and spares in it was over 700 grams!
This was one of the first things that I changed when I started the projects. In my tool bottle, I used to carry a very cheap, poor quality multi-tool. It also weighed 160 grams, which is nearly as much the TC road bottle cage with all tools included! Despite its weight, the only extra socket it had was 8 mm Allen key wrench, which wasn’t even a proper wrench but rather an adaptor that fits over the 6 mm Allen key wrench.
Weight lost: depends on the setup, in my case over 100 grams.
In the tool bottle, I also had a very basic 29er inner tube. Thick and reliable, but also heavy at 225 grams. Since I’m running tubeless and will only need the spare tube for getting back home, it wasn’t a big deal to change it to a Maxxis Flyweight 29er inner tube. It’s definitely less reliable and fragile but will get me back home. Coming in at just below 120 grams (without the wrapping around it), it helped me lose over 100 grams off the bike. It was also a lot more compact which made it much easier to strap onto the bike.
Weight lost: <100 grams
Alongside the tool bottle, I used to carry one of those cheap supermarket pumps. It was very bad quality and also heavy at over 150 grams. I must admit I went a bit overboard with the pump choice since while the Blackburn Airstick SL is super light, it also s*cks at pumping up mountain bike tires. Luckily I have only needed it once in the last few months. Either way, it was still almost 100 grams lighter than the original pump.
Weight lost: 90 grams.
Lighter bottle cage
Back then I also used to have aluminum cages. While the weight lost when moving onto a cheap plastic bottle cage from eBay was minimal at 30 grams, for less than 2€ it still had the best price per weight lost value.
Weight lost: 30 grams.
Going a bit too far before moving onto a hydration pack
Eventually, I wanted to see just how light could I go with very minimal tools. Yes, in the picture on the right that’s a single hex key strapped to the seat post with a piece of an inner tube. The hex key had both 4 and 5 mm Allen wrenches on it, so it had the most common bolt heads on my bike covered, but still not the best idea. I was going way too far with this and any more serious mechanical issue would have meant a hike back home. Just recently I moved onto a Camelbak Classic (Reviewed) which meant all the tools and spares are stored in the pack for now.
What I learned is to definitely pay attention to what you’re carrying on your bike. You don’t need to go too far, but a few simple changes may help you save a decent amount of weight without spending too much money! In my case the bike is over 800 grams lighter than the original, meaning after part 2 the bike weighs in at around 12.8 kg. Stay tuned for part 3!
