As ever the Evo Tech quality is second to none. I have noticed a slight drop on vibration through the bars but this is subjective as different people suffer different levels of numb hands. The score would be 5 stars if I'd eradicated the pins and needles but sadly not. It has improved though. Perhaps a guide note in the box to confirm if thread lock and torque setting is necessary would be a nice touch. Very happy with the quality and delivery. Thumbs up recommendation.
