Polygon Strattos S4 (2019): ChooseMyBicycle.com Expert Review

The Strattos S4 (2019) is built on a ALX performance road full alloy frame. The frame geometry is endurance focused and can be safely termed as an all-rounder as the riding posture on the hoods and drops are suited for both flat out speeds and tiresome hill climbs. The tapered fork is super-light and helps immensely in reducing the overall weight of the bicycle.

This road bicycle from Polygon which I test rode came in a full black frame with yellow as the secondary colour. The matte finish paint job quality was smooth with flashy and bright yellow graphics. Internal cable routing for the gears made sure the bicycle looked neat and also increases the life span of the cables.

The Strattos S4 is equipped with Shimnao’s 4700 Tiagra groupset at the front and rear as derailleurs. Tiagra is still the only stock 10-Speed drivetrain available in Shimano’s road component stable. The shifting was quick and responsive during the test ride. The ST-4700 Tiagra shifters have lost their gear indicators and have gone for the latest look which is similar to their bigger brother’s the 105 and Ultegra.

The Polygon Strattos S4’s stopping power is handled by Shimano Tiagra’s BR-4700 standard road caliper brakes. The dual pivots provide light, comfortable performance thanks to Shimano’s significant increase in modulation.

The Entity Sport drop handlebar on this bicycle was comfortable on the hoods and drops. The bar tape was grippy even with wet hands and gloves. The 48-51cm frame sizes come with a 400mm handlebar and the 54-60cm frame sizes come with 420mm handlebar.

The Schwalbe Lugano 700x25C road tires were perfect for racing and climbing on smooth tarmac. The rubber compounds were strong and does give a long life, thus making it value for money.

The Entity Aion stock saddle was designed ergonomically for an endurance road bicycle to make sure the rider can be seated for long hours without experiencing any soreness.
