I agree with the reviews that complain about the pack shifting or even coming open during a ride. I had this problem for the first couple of weeks. I finally figured out that I needed to pack it with the bare minimum--two CO2 cartridges with one connected to nozzle, one tube (700cx28), one Parktool tire lever, one Parktool GP-2 patch kit, one Parktool I-Beam mini tool. Arrange all contents into roll as flatly as possible. Fold roll loosely so that the both side of the velcro strap line up exactly. When securing to seat rails, ensure that the velcro strap and the padding used for the BOA wire are pressed together. The friction between the two surfaces is key to keeping roll fixed in place when riding. Once I figured this out, I had no problems but feel Silca should have given these instructions rather than learning through trial and error. This should make sense if you give it a try.
Love this bag. Tons of room, compact, and easy to get on and off. During a repair, I can pull off and get to everything with the bike upside-down then easily reattach and be on my way. I converted all my bikes to this bag.
With the advent of COVID - and the lack of long distance "event/charity" rides, I decided to re-think my packing strategy. With this, I can carry a tube, co2 inflator, cartridges, a multi-tool, and a couple of tire levers. That's all I really need for rides that terminate at the house; a more serious breakdown, and it would be a 'phone home' rescue :-)
I've had no issue packing this into the roll. The BOA closure is genius - it is super snug. There's no rattle, no movement of the pack.
I have not yet had to use it "in the field", but I like the concept.
When/if we get back to longer group/event/charity rides, I'll continue to use this, but I'll throw in a couple of other things into a ziploc bag, in a jersey pocket.
Construction quality is quite good. Haven't ridden in the rain, so no comment about water-proof-ness.
All-in-all, as long as you don't need to pack the kitchen sink - this (or the slightly smaller Premio) are a really good alternative.
Likewise - it's easy enough to switch between bikes if you have a common set of tools/tubes/etc
This pump is WELL worth the money. It's really compact, easily fits in my handlebar bag, and strikes the balance between heavy enough to feel durable but light enough to not add unnecessary weight. It extends out a surprisingly long distance which helps make it a really efficient hand pump. Unlike most of the pumps I've owned before, the hose on this pump does not feel delicate and flimsy and the locking, interchangeable chuck is both efficient and convenient. This really is a thoughtfully designed and well made product.
