Troutmoose Underdog Down Tube Bag
Do not underestimate the Underdog. It is the perfect home for those vital items that don’t get used very often but cannot be left at home: repair kit, tools, and spares. Instead of filling up your frame bag with 29er spare tubes, stash it in the Underdog. Made from tough waterproof materials like X-Pac and ballistic nylon.
- Ballistic nylon backing so it will last a long time
- X-Pac construction to keep water out of your stuff. X-Pac is tough and super light.
- 3 Rubberized non-slip contact points to avoid movement and protect your frame
- Tough nylon straps
The bag is designed to be used on the underside of a down tube, meaning it has great crank and chainring clearance even when used very close to the bottom bracket shell. It fits a wide range of tube widths, from skinny steal top tubes to thick carbon down tubes.
Things you can fit into it:
29er spare tube, multi-tool, mini pump, repair kit, tire levers
27.5 Plus spare tube, multi-tool, mini pump, repair kit, tire levers
Spare parts, tubeless sealant, multi-tool, mini pump
700c spare tube, multi-tool, mini pump, CO2, repair kit, tire levers, other bits
Water filtration system, spare parts/tubeless sealant
You get the idea, you can fit a lot of different things in this accessory bag.
