ROTOR INspider MTB Shimano Powermeter (BCD100x4)

The ROTOR INspider MTB Shimano Powermeter BCD100x4

New arrival at ROTORstore, the ROTOR INspider MTB powermeter with Shimano compatibility. Suitable to work with the BCD100x4 Chainrings.

ROTOR INspider MTB Shimano Compatible powermeter is one of the most sophisticated MTB power meters on the market, now compatible with Shimano MTB cranks: XTR 9100, XT 8100 and SLX 7100.

The competitive advantage over other spider power meters compatible with Shimano cranks would be the BCD 100, which allows the use of chainrings starting from 30T, even oval ones.

The new INspider MTB Shimano Compatible also stands out for its lightness, weighing 99 g without counting the chainrings.

Keep in mind that although both chainrings and bottom brackets are optional, there no more compatible chainring options at the market. So we strongly reccomend to include the chainrings at your order. Upgrade now your Shimano cranks with ROTOR.

ROTOR Round Chainrings MTB BCD100X4

ROTOR and VELOPRO Chainrings specially designed for the ROTOR INspider MTB 100X4. The ROTOR chainrings feature Universal Tooth technology, which ensures compatibility with 1×12 and 1×11 Shimano® and SRAM® Eagle® chains. Possibility of mounting chainrings from 30 teeth upwards for all types of users. VELOPRO FlatTop chainrings are compatible with 1×12 SRAM® FlatTop® chains.

 If health and/or performance are important to you, we recommend the oval Q RINGS chainrings. These enable you to pedal more efficiently, maximising the power you develop while pedalling. This ensures better traction on uneven terrain, and less pressure on your knees, resulting in healthier pedalling.
