The Shimano GRX RX820 2x Crankset is built for gravel riders who want tighter gear steps — the kind of control that matters when you're managing pace on a long mixed-surface ride or pushing hard through a gravel race. The 48x31t chainring combination sits squarely in gravel territory, giving you a usable top end without sacrificing the low gearing you need when the road tilts up.
The arms are constructed using Shimano's hollow forging process, which keeps weight down while maintaining the rigidity needed for efficient power transfer. Available in 170mm, 172.5mm, and 175mm lengths, you can dial in the fit rather than defaulting to whatever ships on a build kit. The RX820 crankset sits at the upper tier of the GRX range, and the build quality reflects that — this is a component intended to hold up across seasons of hard use.

Very nice patio umbrella stand
Size: 1-Piece, Color: Black
Very sturdy, easy to assemble and fill with water. I love the water filled stands because it's easy to empty and move around my yard. Highly recommended.

Stable and Easy-to-Use Umbrella Stand
Size: 1-Piece, Color: Black
💧 Water-Filled Design
The ability to fill it with water makes it lightweight to move around when empty but very stable and heavy once filled. It holds the umbrella securely without tipping, even on windy days.
⚙️ Build & Compatibility
The stand feels sturdy, made from durable plastic, and the black color is neutral and fits well with most outdoor decor. It fits standard umbrella poles nicely, and the tightening mechanism is easy to use and keeps the pole firmly in place.
🚚 Portability & Setup
It was easy to set up — just fill with water (or sand if you want extra weight) and insert the umbrella. I like that it’s less heavy than concrete bases but still very effective.
✅ Pros:
Lightweight when empty, easy to move
Very stable when filled with water
Simple to use and adjust
Durable plastic design
Fits most standard umbrella poles
❌ Cons:
Needs regular refilling if you use water (can leak slowly)
Plastic may show scratches over time

Nothing wrong. Stands are just to large for my tables!
Size: 1-Piece, Color: Black
I want you to know that there is nothing wrong with product. It is way too big for my table. I just need to return both stands for a refund. Thank you so much.
