Fancy cross-country mountain biking? Want a waif-like carbon steed to help you to a step on the  podium? But you do not want to spend a crazy amount to make this happen? We have built you your dream frame then. Our M17 carbon fibre XC mountain bike frame is just for you.

We have used aerospace grade carbon fibre to make sure that the ride quality of the M17 frame is out of the world. We also know that even if a frame is comfortable that alone will not win races, so we have worked hard to make sure the frame is light and super stiff where you need it to be stiff. We even made sure that your cables stay hidden through our internal routing.

To create a more substantial bottom bracket area we have used a BB92 bottom bracket shell. This gives our engineers more space to play with and look at the size of our chainstays, and down tube, your pedaling effort will not be flexing ant of these carbon tubes. Our chain stays run all the way to a 142 x 12mm rear thru axle, meaning your wheel will have no room to move it will be held tightly in place.

The downtube mates up with our tapered headtube, you will have no problem finding a fork to fit this XC beast. This frame will then go precisely where you point it, and it will not let you take B-lines you will be A-line through all the courses. Our carbon seat stays, and top tube though are designed to help manage the stiffness from below and cancel out any vibrations, adding a bit of vertical compliance to your ride.

Orange Ball Endless Dog Zoomies
Color: ‌Tangerine - 3.15Inch
My dog was immediately curious about this ball, and it quickly turned into one of the toys that gets pulled out multiple times throughout the day. The movement keeps things interesting and encourages chasing in a way that a regular ball doesn’t. I like that it keeps my dog occupied when the weather isn’t great for long outdoor play sessions. The textured surface provides a decent grip when carrying it around the house. It has bounced off furniture and walls a few times and still looks surprisingly good afterward. The size worked well for my medium-sized dog and was easy for him to grab. There were a couple moments where it got stuck in tight spaces, but that’s more a result of enthusiastic play than a problem with the toy itself. The activity level definitely increased when this ball started moving around. It’s been a fun way to add a little extra excitement to indoor playtime.

Easy to charge and bounces nicely on the grass
Color: ‌Tangerine - 3.15Inch
Getting the kids' backpacks ready usually means the dog gets ignored for a bit and starts pacing. I turn this ball on and toss it out the back door. It has a surprising amount of bounce on the grass, and the random movements keep him running circles trying to catch it. Pushing the button to switch the rolling modes is straightforward. The battery gets me through a few play sessions before it needs to be plugged back in. The outer shell gets pretty dirty outside, but wiping it down with a damp rag cleans it right up. It’s got a decent weight to it, so it doesn't just get stuck under the lawn chairs immediately.

Beware of poor quality issues!
Color: Orange - 3.15Inch, Color: Orange - 3.15Inch
Got limited use out of ball, seemed to have quite a strong motor and was going to be a good buy. But upon going to recharge it for the first time, discovered the USB port was completely loose/not attached. Will steer clear of this brand going forward.

The Ball Never Gets Boring
Color: ‌Tangerine - 3.15Inch
My dog was immediately curious about this ball, and that curiosity turned into a surprisingly long play session. The movement keeps things unpredictable enough that it holds attention longer than a standard toy. I liked that it encouraged activity without requiring me to constantly throw something across the room. The textured surface also seemed easy for my dog to grab and carry around. One thing I noticed is that hard floors allow the ball to move around much more dramatically than carpet. It feels sturdy enough to handle enthusiastic play and occasional chewing. The bright color makes it easy to spot when it inevitably ends up under furniture. Charging was simple and didn’t become a hassle.
