The All-Rounder
4 years ago
I primarily ride/race a mix of gravel and pavement daily, with the occasional 2-track/singletrack thrown in. I also commute to work daily and wanted something that would eliminate my need to have multiple bikes and further annoy my wife with my "hobby" (or realistically, obsession). I purchased this bike knowing it wouldn't do every different type of riding perfectly, but I wanted something that would come close to being the perfect all-rounder. And it is. Gravel: I've fit 40C WTB Nanos with room to spare! The riding position with the stock stem height is plenty comfortable for several hours on gravel. Coming from my previous steel gravel bike, this thing blows it out of the water. Smooth, comfortable, fast. Road: I have a separate wheelset with 32C gatorskins for road riding. Even on the road, this thing will keep up with nearly any other midrange road bike on the flats. You can snag KOMs from your smug local strava nemeses on this, all while they worry that a small insect is going to break their carbon frame. The gearing made climbs a piece of cake, making long rides much less tiring. CX: Haven't had a change to race CX yet. Apparently there's some sort of pandemic going on? I'm excited to try these brakes out though. Hydraulic is the real deal. Cons: My cleat position on the size 54 creates some minor toe overlap, which is a bit annoying on technical trails. The weight is ok. I have it at 23 lbs after adding pedals, 40C tires, bottle cages, lights, and converting to 1x. Bottom line: This bike is the ultimate all-rounder. It can handle whatever gravel you throw at it. It will embarrass 50 year old dentists on $10000 Specialized Venge's. You can cover it in mud and it will ask for "a bit more, please". I love this bike. It does anything I want it to do and surprises me (in a good way) everyday.

I was a fixed gear loyalest for the longest... I don’t know what I was fighting for 23CM tires have a place, but it’s not under me. Already have done some local trails what a wonderful experience to cruise to the trail hit the train hard then ride home comfortably. The smoothest bike I have eve ridden.

Great all around!

As advertised, this bike does it all pretty well! In the year I have had it, I have used it for 40+ mile road rides, gravel and fire roads, and cyclocross events and I have yet to encounter any issue of consequence with it. The breaks are great in any condition, the geometry doesn't cause me any pain on long rides, and it rolls very smoothly. This is the first bike that I have spent considerable money on and I couldn't have asked for a more well rounded machine right out of the box. Very excited for another season on this bike!

Most fun I’ve had on a bike in a long time.

This bike is a blast. It can move like a road bike but crush the bumps in the road like a full gravel bike. Super smooth and a great aggressive geometry that doesn’t leave me in pain after 40 miles. A bit heavier than some other gravels out there but not enough to regret the purchase.
