Lezyne Bicycle Saddle Trainer 2,973,059,801 Road Case Caddy, Black, 45.5 x 34.0 x 26.5 CM, 0,35 litres, 1–Sb-Rdcaddy-V104

It’s not cheap, but it’s very well made, unlike my old £6 cheapo one that fell apart. There’s sufficient padding to stop any rattling when on bridleways. I can get a mini-pump, a compact Topeak tool-kit, puncture parches and a small adjustable spanner in, and the velcro strapping seems very robust and well stitched.

Fits snug under the saddle, just big enough for a full puncture repair kit and could fit in another few bits and pieces, allen keys etc.But fiddly to put on and off but it's not something I (hopefully) need regular access to.

Not tried fitting a tube in there yet, but plenty big enough for 2 x CO2, valve adapter, tubeless repair kit and multi-tool.

I purchased this because I liked the clean look and it would not obstruct my rear light.I managed to fit 1 x tube, 2 x CO2 16g cannisters, CO2 valve, 2 tyre levers and a small Park tool patch kit.I think I could replace one cannister with a small tool. Also there's some gaps to slide some loose allen keys in.its tight in there, but it fits!Its ideal for short rides.

Great saddle bag for keeping your tools and repair items. I am using on a dropper post and its not rubbing on the back wheel when I lower the post.It won't hold a tube but I have a frame strap for that.

Looks so smart underneath the seat. Nicely tucked away from site and big enough for a tube and levers.

Really good. I wanted something very small and sleek. This did the job. I can get tube, mini tool and tyres levers in. I did have to get some new flat tyre levers. My old Park Tool ones didn’t fit.

Perfect size for road riding, quality materials and very well made. Secures well to the bike.
