SILCA Speed Capsule TT

Used this for the Dirty Kanza and did not disappoint! Easy access aero and generally slick..and i think both of the DK 200 2019 winners used them as well (mens for sure). The compartment is big...could be a touch bigger and/or maybe have some slick low-pro side pocket but worked well. Zipper works but does pull at the end when you zipp it all the way (so don't do that) i put in a little plastic divider to divide my gels from my blocks (screwed it down and extended the base which made it stiffer and helped with the zipper issue)...test it out and see what works for you before the big day but a must have for any endurance event where aero and look'n good (i'm not gonna spend $$ on a coll bike and then slap a cheesey bento box on it) counts.

I just purchased a new bike with a top tube mounting location, and I wanted something that would hold a energy gels, bars, etc. The Silca TT bag is perfect -- large enough to hold some nutrition, narrow enough to not cause interference, and aero enough to be low-profile. Exactly what I wanted.

This was easy to attach and fits great on the top tube of my Salsa gravel bike. I can fit some small snacks in there for my rides.

Love this thing Looks cool too matches my bike

I little on the small side, but works well to hold a few snacks, keys, etc.

Couldn’t fit much. Not worth it.

Product is much smaller than expected, not much going in this bag.Bag is way over priced!Be careful what you place in the bag as the mounting screw heads are exposed and scratched multi-tool case on first ride!
