Great pouch

Review by Dave W. on 31 May 2025 review stating Great pouch

Great pouch for the bike, just the right size to conveniently store gels and food for the bike stage of triathlons.
Straps are a good length to be able to cut to size, fits well to the bike

Bought as a gift for my husband - I’m told it was really easy to use while he was out on the bike and holds quite a few snacks/gels during longer rides.

Top tube bag

Review by Angela N. on 5 Sep 2024 review stating Top tube bag

Excellent size for nutrition for long course. Stays firmly in place and zip is easy to use with one hand.
Confused by very long straps which I cut down.

Just the right size

Review by Michael B. on 27 Aug 2024 review stating Just the right size

Small enough to not get in the way, big enough to store 4 hours of nutrition. Material is a lot tougher than other bags on the market.

A: Hi, To fit fasten to the handlebar post and top of the frame, You can cut the straps if you please however we recommend keeping them incase you want to use it for another bicycle.
