The useful one. Castelli Undersaddle XL Seatpack. OK its not big, its not trendy and really it's the bag you never ever wish to even open. But as insurance policies go the Castelli Undersaddle XL isn't a bad one.

The XL is designed to carry a couple of tubes a multi tool a pump or C02 system and maybe a few £££s. Held on my molded magic Velcro (with a seatpost stabilizer ) the bags simplicity is also its biggest asset. Water resistant fabric water resistant zips internal mesh pocket and well that's it. Just high quality minimalism.

Castelli saddle bag xl

Nice bag,superb quality holds a tube, tool ,2 gas canisters and pump head no problem ,fitting under the saddle rails is ok but velcto fixing for seat post is too short for oval type seat posts,pinarello prince/dogma etc it’s just to short , it’s ok on round standard posts, with just fixing under saddle it should be ok ….we will see sorry castelli 3 stars

Spare Tyre and Tools

Castelli XL Saddlebag

I now own two of these for my main bikes. They're excellent and not that XL either. Perfect for road training on my race bike. Will take 2 tubes, levers and a small multi-tool perfectly, with space for emergency cafe money. They are very easy to fit and remove for racing. It has a sleeve to take a micro pump too and is very secure, as I hate bulging jersey pockets and like to carry two bottles on longer training rides. Rode my previous one through last winter and LEJOG, where contents remained dry. Recommended for any roadies. This is a quality saddlebag.
