Holding on, steering and braking are the most important tasks a bike grip has to transmit - and of course, it should also be comfortable. Only a grip which fits perfectly to the hand can perform these tasks.
This is why the SQlab grips are available in different sizes. The SQlab grip size determination allows selection of the correct grip size.
Pressure mapping on the contact interface hand and grip, have shown that the pressure in the outer region is the largest. This is also where the ulnar nerve runs. The ulnar nerve is responsible for the sensitivity of the ring- and little finger.
We have therefore increased the contact area in the outer region of the grip and hence reduced the pressure here.
The carpal tunnel supplies thumb, index and middle finger. Here the nerves exit and branch off to the fingers. A very sensitive area, which can usually be relieved by selecting the correct handle bar sweep for a straight transition from lower arm to hand. Here we should also pay special attention that this area is pressure relieved! Several conventional ergonomic grips have a so-called relieve wing which extends too far inwards. Often this relieve wing is too hard and can cause unwanted pressure to the carpal tunnel pass.
Take a look at your fingers as the wrap around a handlebar...
Correct: pretty square.
This is why we have adapted our grips to this shape and created an ergonomic hexagonal wave form that fits perfectly in the hand and provides an ideal secure grip for the hand.

The relief wing is designed to reduce pressure to the outer palm area of your hands when hands are supporting your weight by resting on the handlebar.
The wing should be positioned such that it points down slightly. The support of the wing should only be noticed with increased weight on the hands.
Do never position the wings too high. This would prevent a sharp bend in the wrist, but it would also compromise the ability to maintain a good grip of the bar at higher speeds and the associated higher loads.
Even with a relaxed riding position and a loose grip, the grips should provide a good secure hold of the handlebar. This is why our wings are as large as necessary and as small as possible and only positioned very far outwards on the grips. The squared-off contour at the front and lower side of the grips considerably increase the ability to maintain a strong and secure hold.
Holding, steering, braking are the main tasks that are controlled through the bicycle grip and while performing these tasks, it should still be comfortable. Only a grip which fits perfectly to the hand can accomplish this.
That is why we have developed a method for determining the optimal grip size. Our grips, depending on the model, are available in two or three different sizes / diameters.
It’s not a given, that all ergonomic grips relieve pressure on the carpal tunnel. But this is precisely where we have placed great emphasis. The relief wing on all SQlab grips is positioned as far as possible to the outside. Additionally, this results in improved grip, especially when supporting the body weight at the front. All SQlab bicycle grips are made of at least three different materials and are naturally free of harmful substances.
For an optimal fit between the hand and the bike grip, we recommend getting the free "grip & fit" measurement which is available here or on-site in specialist bicycle shops.
