Product: Shimano Ultegra R8000 Cassette 11 Speed 11-28T, 11/28
Brand: SHIMANO
Color: Gray
Description: Shimano's Ultegra group is one of the most popular out there with good reason: it's the perennial favorite when you factor the performance-to-dollars equation. With different demands for drivetrain ranges required for road, gravel, and CX riding, Shimano has created cassette ranges designed to allow the R8000 drivetrain to easily satisfy the needs for a variety of riders. The Ultegra CS-R8000 Cassette ranges as high as 32t, so you can set up the new Ultegra (or Dura-Ace R9100) with the range you need for gravel epics, 4 corner crits, hill climbs, junior nationals, and everything in-between. Shimano's experience in forging, machining, and engineering allows for an enormous amount of technology that goes into tooth design, shaping, and shifting ramps. The cogs themselves are constructed from a nickel-plated steel that prevents corrosion and is slow to wear. Ultimately, this leads to cassettes that shift smoother and more precisely--and last longer--at a price that's friendly to the self-sponsored racer. The top five cogs are grouped as three and two, respectively, and are riveted to anodized aluminum spiders that add stiffness to improve shifting. The remaining six cogs are individual with spacers between, and an anodized aluminum lockring screws into the freehub to hold the entire assembly together. One spline of the cassette is wider than the others and corresponds with the splines on the freehub, so the cassette cogs can only be installed with the right clocking of the shifting ramps, timing them for perfect chain pick-up and release. This innovation is true to Shimano's Japanese culture, which uses the term "poka-yoke" to refer to features--like these guiding splines--that serve as built-in wards against user error.
Cog Sizes: 11 x 25t, 11 x 28t, 11 x 30t, 11 x 32t, 12 x 25t, 14 x 28t
Cog Material: nickle-plated steel
Freehub Type: Shimano 11-speed road
Carrier Material: aluminum
Claimed Weight: [11x25] 8.2oz (232g), [11x28] 8.9oz (251g), [11x30] 9.5oz (269g), [12x25] 8.6oz (243g), [14x28] 10.6oz (300g)

Product: Runbell - Handheld Running Bell - Japanese quality brass bell delivers a harmonic ring to warn others of your approach. Useful for trail running, running stroller, unicycle, classroom (For Him Copper)
Brand: Runbell
Color: Rose Gold
Description: AVOID SURPRISES AND COLLISIONS DURING YOUR RUN
Your feet pound the path. Your breathing is deep but steady. As you lengthen your stride the trees along the path become a blur.

Then, a hundred yards ahead of you, you spot the blockade—three people walking abreast and chatting cheerfully. They probably don’t even realize they’re blocking your path.

You clear your throat, but the pedestrians are engaged in conversation and do not hear you.

What do you do? It feels rude to shout, and even ruder to barrel your way between them.

Runbell lets you communicate your presence in a polite way. The clear ring of the bell cuts through traffic and conversation noise to get the attention of others who share the trail or sidewalk.

WHAT OTHERS ARE SAYING
“The greatest fitness accessory on Kickstarter” – OUTSIDE ONLINE

“The runner’s version of the classic bicycle bell” – Runner’s World

SIMPLE YET INGENIOUS
Runbell lets you alert pedestrians, bicyclists, and other joggers that you are drawing near, without having to shout a verbal warning. It produces a bright, clear “ring! ring!” that cuts through ambient noise. It is also a more polite solution than a warning shout or a last-second, grunted, “Coming through!”
ADJUSTABLE TO YOUR FINGERS
We designed Runbell to be slightly oversized, to fit even large hands comfortably. Two pairs of silicone inserts are included with every Runbell, so you can reduce the ring size to fit YOUR finger perfectly. On cold days, leave out the insert and wear Runbell over your gloves.

HOW TO USE:
STEP 1:Fit Your Fingers
Slide Runbell onto your index and middle finger. Adjust with removable silicone inserts.
STEP 2: Ring Ring
Reach with your thumb, push the hammer forward or pull to the side, release. Enjoy Runbell’s signature ching!
STEP 3: Say "Thank You"
JUST RUN WITH IT - Runbell works. Try it and see. Walkers often complain that runners overtake them in surprise. Give warning before you pass and make your run easier.
MUSICAL - A high quality brass dome produces a loud, powerful, musical ring. You'll love the ring so much, you'll ring it more than you need it!
LIGHTWEIGHT – Weighing only 1 ounce, Runbell is small, stylish, and lightweight. Running with a Runbell has never been easier. You'll barely notice your new running gear
ADJUSTABLE - Slightly oversized with two pairs of silicone inserts, adjust to fit YOUR fingers. Cold outside, then wear gloves because Runbell is oversized for the average fingers.
QUALITY GIFT - Runbell comes in a beautiful packaging and makes a very unique gift for the runner who has everything. Plus Runbell is proudly made in Japan. Enjoy quality craftsmanship from the land of the rising sun.
