Dunlop Biofibre M2.1 Tennis Racquet Review

Dunlop introduced a radical new design in 2015 with the debut of the iDapt racquet line. Rather than bank solely on that innovation, they have also refreshed some of their traditional models like the revised Dunlop Biofibre M2.1. This racquet plays like an advanced player frame but cuts some of the weight from the Tour model for a faster feel. It carries over technology from the previous 2.0 model such as a Biofibre shaft for better vibration damping, Aeroskin CX for faster swinging and MoS2 grommets for more spin and power. Here’s a look at how the update performs in on court testing.

Groundstrokes
Control and accuracy are hallmarks of the Dunlop M2.1’s game off the ground. The 95 inch head played with high accuracy and nimble response from either side. I found the sweet spot to be a bit small and the power level dropped a bit off center. This led to a few more mishits and short balls on my forehand side than I typically see with larger, more forgiving frames. The power level of this racquet was largely dependent on string selection. With low power poly, players are going to need to be able to supply the racquet head speed needed for pace. A softer string or lower tension should add a bit more pop to the frame. The racquet’s solid 11.6oz strung weight allowed me to hit a heavy ball and keep opponents pinned deep when my timing was on. Spin production from the 16x19 pattern was about average for a smaller head size and I did miss the extra spin from more open patterns, even other 16x19 ones. The trade off was that this frame was great for stepping into the court and flattening out the ball. I had great capability to step in and drive backhands down the line. My backhand slice was also very effective as the weight helped keep the ball low and skidding away.

Volleys & serves
Net play with the M2.1 was very rewarding. The head light balance and manageable weight provided quick maneuverability, allowing me to position it quickly during exchanges. I found plenty of punching power to finish high volleys. There was enough feel on contact for me to feel comfortable mixing in touch and drop volleys to keep opponents off balance. I also found the smaller head and nimble feel to be effective at creating a wide variety of angles, allowing me to continue attacking as I came forward.

Pinpoint accuracy was the highlight of my time serving with the Dunlop M2.1. The lack of free power made it a bit more challenging to go for powerful flat serves. I had better luck using the excellent directional accuracy to pick aggressive targets and move my opponents out of position. I found solid spin for second serves but I didn’t quite have the same high bouncing kick as other frames can produce. I found myself using more slice second serves because the weight behind the ball kept them low and I was able to place them very wide, especially on the ad side. Overall, this racquet will do well for players who rely on variety and accuracy to win service games.

Feel/Comfort
The feel of the M2.1 was a nice middle ground for Dunlop’s recent offerings. I found it less stiff than their previous versions, but it did still offer a crisp, firm response. There was a bit more vibration off center and it became easier to notice the stiffness of the frame. There was a good, connected feel on contact, which further increased my confidence in the racquet’s accuracy. While I didn’t find the racquet uncomfortable, players with sensitive arms will want to use a softer string to help ease the blow on off center shots.

Overall
Advanced players who want the performance of modern player frames without all the weight associated with them, will enjoy the Dunlop Biofibre M2.1. It offers a low powered, precise response perfect for controlling the court with accuracy. Combined with its fast net play and scalpel like serving, it is an attractive option for attacking players who want to go after aggressive targets.
