Which crank is the ergomo^® sensor compatible with?

 ISO square (Campagnolo standard) 
 Ocatlink (Shimano) 
 ISIS

     Does the ergomo^® sensor fit a 73 mm bottom bracket housing?

Yes, the ergomo^® spin fits the 73 mm housing. As well, there will be ergomo^® pro ISIS Sensors available with 73 mm as of November 2007.

 ergomo^® pro ISIS BSA 118 mm
 ergomo^® pro ISIS ITA 108 mm
 ergomo^® pro ISIS ITA 113 mm

 Which materials are used in the ergomo^® sensor?

The axis of the sensor is made of hardened special steel. The hull of the sensor is made of hardened aluminium. All made in Germany.

 Why is the width of the 102 mm ergomo^® sensor 107 mm?

The smallest possible width of axis at the moment is 107 mm. This is due to the necessity of measuring within the inner bearings. This version is compatible to 102 mm.

 What has to be kept in mind while calibrating?

Please note  the K-factor (K, cal) (written on the sensor) before installation. The K factor needs to be programmed in the ergomo^® pro computer followed by the offset. To do this the right crank is to be accelerated steadily. Best results can be achieved when the biggest chain ring is used in combination with the smallest sprocket.

 Is the ergomo^® sensor water proof?

Yes, it is 100% water proof! The sensor is water secured in several different ways and no moisture and/or dirt can get inside.
