Tri Bike Face-Off: Cannondale Slice 5 Vs. Quintana Roo Lucero

Not only are the Slice 5 ($2,149) and the Lucero ($2,650) similarly priced all-carbon tri bikes, but they also have nearly the same geometry. We performed a side-by-side analysis to find what differentiates these two similar-fitting rides.

Frame fit

Both bikes are designed for a moderately upright and comfortable triathlon position. The most important fit dimensions of the S, M and L Lucero frames are within millimeters of the corresponding Cannondale sizes. The Lucero comes in four sizes; the Slice comes in six.

Component function

Slice 5: Although the Shimano 105 kit with off-brand Microshift shifters isn’t the most glamorous, it executes surprisingly precise rear shifts. The FSA Gossamer Pro crank is effective, but doesn’t shift as crisply as the Lucero’s Ultegra crank. The Fizik Arione Tri 2 saddle was a welcome up-spec on this price-sensitive build.

Lucero: The Lucero boasts top-notch shift performance. The mixed-level Shimano kit shifts flawlessly in both the front and rear, highlighted by the sharp front shifting thanks to the outstanding Ultegra crank. Testers found it difficult to get comfortable on the stock saddle.

Ride experience

Slice 5: The Slice is unfailingly steady. It predictably tracks a line when cornering, riding out of the saddle or pushing a hard tempo in the aerobars. It mutes road vibration effectively.

Lucero: The Lucero is quick and nimble. Its agility and willingness to turn does, however, require the rider to stay vigilant through sweeping corners. The frame is more than adequately stiff but the bike flexes slightly more than the Slice when sprinting.

Fit adjustability

Slice 5: The Profile Design T2+ aerobars add a massive range of fit adjustment. The extensions and elbow pads can be moved substantially in the fore-aft direction. The pads are positioned high above the basebar, which allows the Slice 5 to accommodate a taller, more conservative position but prevents the elbow pads from being lowered close to the top tube. The seat post can set the saddle at a 78-degree effective seat tube angle.

Lucero: The elbow pads on the Vision aerobars can be dropped substantially lower than the pads on the Slice’s T2+ bars and can be lifted vertically by two centimeters. These bars are a better match for the rider wanting to progress into a low position but the reach distance to the pads and extensions cannot be adjusted. The seat post allows the effective seat tube angle to be positioned anywhere between 75 and 81 degrees.

Pick your match: The Lucero offers unmatched component performance for the price. The Slice has a tighter ride feel and extra fit adjustability.
