Description

SRM gear shifter set Lite Version

The Lite version of the SRM shifter set is exactly the same as the full version but without all of the extras.  With parts becoming more expensive and difficult to get this new version is easier for me to make and is a way of keeping a really great price.  The actual shifters are exactly the same.

Unlike other shifters available at the moment ours can be customised, upgraded and parts can be replaced.  Most shifters are sealed and it is not easy to replace parts.  Our shifters can be opened up easily and most parts can be replaced.

Beautifully made from Aluminium which is lightly sandblasted before being anodised to give the highest quality finish.

Dual buttons on a custom PCB.  Using dual buttons inside the shifter ensures that the arm will not rock from side to side, it also provides redundancy.  The buttons we use are mechanically rated at 1,000,000 clicks and even when they wear out, you can simply replace the PCB with a new one from our spare parts catalogue.

Shifters have no fixed wires.  There are two plugs on each shifter so you can easily replace the cable or change it if you need to fit the shifters to a different wheel.  One plug is underneath the shifter and the other is at the back, either can be used. The plugs on the shifters are JST PH 2.0, 2 pins.

We are confident that these are some of the lowest and most compact gear shifters on the market.

Don’t be put off by the price of these gear shifters they are very high quality and made from machined Aluminium.

Specification:

•          Weight: 48 grams with 5mm tall magnets and the Aluminium arm but excluding the paddles.
•          Height: 25.27mm
•          Width: 28.80mm
•          Magnets: N52 5mm
•          Material: Aluminium
•          Changeable Aluminium arm (Carbon Arm is not included)
•          Adjustable travel (Via 2 grub screws)
•          Dual switch buttons on replaceable PCB
•          Button mechanical life 1,000,000 gear changes **
•          Removable cable
•          Dual bolt mounting pattern

** We have tested a set of shifters to 500,000 gear changes using a mechanical solenoid to press the shifter repeatedly with a force of 24nm, so, far more force than we would expect them see in real use.  This is the equivalent of 25,000 laps of Silverstone GP circuit or just under 100,000 miles.  There were no signs of wear to the shifters after this.
