The Frog Chelsea 27.5” is built around a hardtail Alloy frame. The Alloy frame has a conventional frame geometry, which was comfortable to ride. This frame was capable of taking in vibrations of the surface on rough trails and urban roads. This lightweight Alloy frame made it easier to accelerate and to ride on inclines.This hardtail MTB comes with Zoom 389 front suspension fork with an impressive 8mm travel. This travel was smooth in working during the test ride and the mechanical suspension lockout feature was helpful in making the fork rigid for a smoother riding experience on flat surfaces.

The Frog Chelsea 27.5” comes equipped with Shimano Tourney TY5 at the front and rear as derailleurs. These are entry-level gearing components in Shimano's MTB hierarchy and they performed to their limits during the test ride. On rough urban roads and flat trails, these derailleurs were ideal for quick and short gear changes. The Shimano EZFire 21-Speed Shimano trigger shifters were easy to use and in easy reach from the handlebar grips.

The Chelsea 27.5” from Frog, which I test rode came with Black as the primary colour with Blue and White as the secondary colours for the graphics and text. The matte finish paint job was top notch in quality. The Blue brake and gear cables were a nice touch to make them colour coordinated. The Blue/Black saddle with bold text and the England flag is definitely eye catching. Chelsea is a popular football club in London. With the same colour scheme of Chelsea F.C, this bicycle's design is sure to be popular amongst football and Chelsea fans.

This MTB's stopping power is handled by a pair of Zoom Mechanical Disc brakes at the front and rear. These brakes were powerful, safe and balanced on rough and smooth roads. Both interval and jamming of brakes felt in control when used during the test ride.The Alloy handlebar on this bicycle was both comfortable and wide enough with a raise from the middle to give the rider an open chested riding posture.

The 27.5” x 2.2” MTB tires on the Frog Chelsea 27.5” were heavily treaded to generate a lot of traction on rough surfaces. The 27.5” circumference made it easy to ride over rough trails and urban roads. The stock saddle was wide and had enough cushioning to keep the rider comfortable on bumpy rides.
