- Reach Reach is the horizontal distance from the center of the cranks to the center of the head tube, measured at head tube level.
- Stack Stack is the vertical distance from the center of the cranks to the center of the head tube, measured to the top of the head tube.
- Effective Top Tube Effective top tube is the distance from the center of the head tube to the center of the seat tube/seat post, measured parallel to the ground.
- Seat Tube Center to Top Seat Tube length is the measurement of the seat tube, from the center of the cranks to the top of the seat tube.
- Head Tube Length Head Tube Length is measured from the bottom to the top of the head tube.
- Head Tube Angle Head Tube Angle is the acute angle between the head tube and the ground (measured towards the rear of the bike)
- Seat Tube Angle Seat Tube Angle is the acute angle between the seat tube and the ground (measured towards the rear of the bike).
- Bottom Bracket Height Bottom Bracket Height is a measurement taken vertically from the ground up to the center of the cranks.

Great first gravel bike
I currently own a Cannondale Synapse that I bought from REI about 10 years ago. The bike is great but a little challenging and rough when on local DC area bike routes with my family. I bought the Cannondale Topstone 3 as my first gravel bike to use on these rides and so far it’s been a great decision. The trails are more manageable and my confidence on the Topstone is day & nite from the road bike. I get the position and feel of my road bike with the confidence of a hybrid or light mountain bike. Plus it’s a Cannondale which is a superb brand and solid performance. Highly recommend this bike to those looking for a gravel bike.
Great All Rounder
I've been brainwashed into thinking thinner tires were faster and was a little worried about what I would experience. I was looking for comfort and this bike seemed to fit the bill. Personally I cannot tell the difference between thin and thick here. For me being able to add fenders was a great plus. If you are between sizes like I was, perhaps opting for the smaller one would be better. I chose the bigger one since the smaller one was out of stock. The reason I say this is because I feel like getting a shorter stem would make the bike perfect, and because the seat post will not go all the way down without chopping it. Grateful for the micro adjust, but you will need 2 differenct hex wrenches to adjust the angle and the height. Not sure if this was a Cannondale thing or not but front derailer needed adjusting right after leaving the store, the steering tube just five days later. Also, check the tightness right after purchase, some of my mounting bolts were loose. Finally, the bottom bracket bearings are offset inside the bottom bracket flange, a sure dirt/mud catcher but also will make servicing problematic. Take a close and see if you can live with this.
