The MCS 110BCD 5 Bolt Spider is a black, five-arm alloy spider with a 23.8mm center hole and five 110BCD mounting holes, designed for use with 1-piece bicycle cranks.

Description

The MCS 5 bolt spider is a 110 BCD alloy spider that carries the drive from your cranks out to the chainring. It is 5mm thick, machined from aluminium, and weighs 64.3 grams.

The 23.8mm bore fits 1 piece cranks as it comes. If you are running 19mm cranks you will need a 23.8mm to 19mm adapter, which is sold separately.

Features

5 bolt, 110 BCD. A standard 5 bolt 110 BCD pattern, so you can bolt on the chainring and tooth count that suits your gearing.
Made for 1 piece cranks. The 23.8mm spindle hole fits 1 piece cranks as it comes, with no extra parts needed.
Runs 19mm cranks too. Add a 23.8mm to 19mm adapter, sold separately, and it works with 19mm spindles.
Alloy, 64.3 grams. Aluminium construction at 64.3 grams keeps the weight down out at the cranks.
5mm thick. A 5mm thick spider to get power from the cranks to the ground.
