Castelli Undersaddle XL

Fits a tube, co2, a mini pump and multi tool. Cant believe others don't make bags this size.

Fits well under saddle, secure and good storage for fairly compact bag

Fantastic saddlebag. Plenty of room inside with a nice compartment underneath to put a pump. Also the reflective logo is a nice touch. The only thing stopping me giving it a 10 is I'd like to have seen the strap that fits around the seat post a tad longer, as it just goes round my aero post. However, highly recommended.

Pros & Cons

Fantastic saddle bag, deceptively large enough for two inner tubes, tyre leavers, multi tool, and room for snacks, it's like a tardis! Very well made and looks great on the bike.
