FIT AND PERFORMANCE

The carbon Service Course SL seatpost is specifically tuned to be more shock absorbing than the “comfort” seatposts on the market, while still passing our strict internal MTB strength test. Flex engineered into the lightweight carbon tube keeps the rider comfortable over any terrain. Better fit means better performance, and if your saddle is out of position, you’ll waste energy with every pedal stroke. The secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt head accessibility. With 0mm and 20mm setback options, it’s possible for nearly any rider to achieve the perfect fit, and the clamp works with all saddle rail types.

My dog loves these
Theme: 2 Pack, Size: Medium
My dog loves these balls. I would just keep in mind that large dogs will be able to chew them and rip the ball apart due to design. Just something to keep in mind if you have a chewer. Great that they glow in the dark. Fun for dusk or night time ball

Good for playing catch with dog in failing light.
Theme: 2 Pack, Size: Medium
Several pluses with this product. On start, the downside for some is shorter distance throwing wiffle ball effect. Now the very good points. Glows from UV light exposure for dusk, second part is easy for dog to breathe when running around with it. Works with the Nerf lighted launcher also with it it "charges" them up along with the "Chuckit" handle. The original one for the Nerf one lasted 3 throws before busting. . . Belgian malinois so no surprise. I'll definitely be ordering more in the future.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!
