The one piece of Si we love to see on their bikes is the one-piece SpideRing chainring on their lightweight Si cranks. It’s not as dramatic here, but as a package with the frame, it all seems to work quite well to mute the physically draining white noise of crappy roads. On some flex posts, I can look down while pedaling and see the saddle’s nose bobbing up and down. The last piece of the SAVE puzzle is their 25.4 seatpost with built in flex. All done to keep the ride quality consistent across the the line, whether you’re riding a 44 or 61 (58 tested). Not noticeable are the three different fork offsets, lower bearing sizes and frame layups used across the size spectrum.

The frame is rated to clear 32mm (measured) tires, it’s shown here with the stock Vittoria Rubino Pro 700×28 tires. Others do this, Cannondale’s been doing it longer, and it shows through in the ride quality. More to the point, the Si takes the form of functional improvements like modular cable ports that can be swapped for Di2 junction box holders on bike equipped with electronic shifting.Īnd flattened, shaped stays and fork legs designed to improve vertical compliance without losing lateral rigidity. The seat tube is offset to the left to clear the front derailleur and maximize cross section, and the chainstays are shaped differently to improve tire clearance and use a double chainring. Well, technically, it is an asymmetric design, but only in that driveside and braking areas are reshaped and strengthened to handle those stresses. No, there’s no asymmetric rear end or wheel builds here, letting you swap in any modern thru axle disc brake wheelset. And both get some of their “Si” Systems Integration, though nowhere near the level of the latest SuperX or Scalpel bikes. Both versions benefit from their SAVE micro suspension at the seat- and chainstays, fork, and seatpost. The 2018 Synapse is offered in two frame trims – the HiMod at the top, and this Carbon model with BallisTec layups. Here’s how it performed… 2018 Cannondale Synapse Carbon Disc Overview Add in much improved looks over earlier models, sleek cable routing and a hidden seatpost binder, and it looks very much like the total package riders who just like to ride a lot. Whether you wanted to go fast or go long, or both, its combination of a stiff but forgiving frame, big tire clearance, and intentional compliance could deliver.
Introduced last year, the 2018 Cannondale Synapse was designed as an endurance race bike.
