Product Info

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.
