I used to have a Topeak saddle bag which always felt a bit bulky and ugly on my sleek carbon bag. This one is lovely. Initially it looks and feels annoyingly small but I managed to get a tube, 2 tyre levels, multi-tool, a puncture repair kit, and a CO2 inflator in mine!!!! For some reason Castelli put a stupidly long care instructions label inside. This made it difficult to test how much I could fit in when I was deciding whether to keep the saddle bag or not. Obviously if you keep it you’d remove it, but it’s annoying when you are testing it out. Overall I’m really pleased with it. It holds much more than you think, looks sleek, and feels very secure. My only concern is the strength of the zip. Care should be taken when open and closing.

Perfect and unatrusive, big enough for a tube, multi tool and a couple of tyre levers. Waterproof also and minimal mountings, simple loop strap. Very happy

Q & A
1 question answered
Will it hold 2 tubes, multi-tool and 2 tyre levers only - nothing else?
Hi Bill, We've found you can only fit one tube, a multi-tool, the smallest CO2 inflator and tyre levers in this item and we find it that would be the limit. Perhaps, this would be a suitable saddle bag: https://www.sigmasport.co.uk/item/Specialized/Wedgie-Saddle-Bag/2W69 I hope this is helpful. Kind regards, Nathaniel.
