: The Cosmic 3 27.5 is a Hardtail MTB and is built using Alloy. This frame has a slanting top tube which made it easy to get on and off the Bicycle and also safer for the rider on bumpy rides with that extra standover clearance. The frame geometry ensured the rider was upright with relaxed shoulder and wrist positions for a pain free ride.Being a Hardtail the 3 27.5 comes with a stock front suspension fork with an 8mm travel and a mechanical lock-out which helps in better acceleration on flatter surfaces.

: Cosmic have started using Microshift components on some of their Bicycle models. Microshift as a brand is on par with Shimano in terms of performance and quality. The 3 27.5 comes equipped with a 9-Speed Microshift Marvo at the rear along with Microshift Marvo 3-Speed at the front. The Microshift drivetrain on this Bicycle was both quick and smooth in shifting with no lag experienced during the test ride. The 27-Speed gearing system is controlled by Microshift's TS38 trigger shifters.

: The Bicycle which I test rode came in a full Black primary colour with Red, Light Blue and Silver as the secondary colours for the graphics and text. The graphics were bold with contrasting colours which made the Bicycle look bright. The matte finish paint job was smooth and the tube welds were perfectly molded.

The Cosmic 3 27.5 comes in 3 different colour variants
: The stopping power on this 27.5 inch Hardtail MTB from Cosmic is taken care of by a pair of Tongli branded Mechanical Disc brakes. These brakes were of good quality with rotors and the disc plates which were powerful in stopping amidst traffic.This MTB handlebar with a minimal raise was wide and gave optimum control for the rider when riding through fast paced flat trails and also when maneuvering sharp turns.

: This Cosmic MTB comes with Kenda 27.5” x 2.25” MTB tires. These tires have bulky treads and a uniform tread pattern which provided great traction on trails and flat muddy surfaces. This wheelset was ideal for faster rolling resistance as well as being balanced on flat trails.The Stock Saddle from Cosmic wasn’t the most ergonomic in design but had enough cushioning for a soreness free ride.

: This Alloy Hardtail MTB was comfortable to ride thanks to its frame geometry and the wide handlebar. The 8mm front suspension with lock-out made it easy to ride on muddy trails and wet urban roads. The 27.5” Kenda tires were heavily treaded and fast rolling as well. The 27-Speed Microshift drivetrain was smooth in shifting and definitely on par with Shimano. Priced at Rs.26,8(as on 9th November 222) the Cosmic 3 27.5 is an ideal choice for anyone looking to buy an MTB for riding on both urban roads and flat to moderate trails.
