2XR Spider
All 2XR spiders are designed to add flexibility to choosing chainline while not locking you into proprietary chainrings. Spiders are interchangeable and fit on any spindle allowing you flexibility in gearing.
1x or 2x on road? Same spider.
Boost? Superboost? Same spider.
Want to use your track chainring on your fat bike? It’s impractical, but possible š
104×4: A spider for mountain through fat bikes for mountain bike chainrings. Chainring can be mounted on either inside or outside position depending on chainring requirements. Also compatible with Gates Belt Drive 104×4 chainrings.
110×4 Shimano Style: A spider has an asymmetric 4 bolt pattern popularized by Shimano road groupsets. This allows you to take your chainrings off your Shimano cranks and install them on the 2XR spider for perfect shifting. Fits 11 and 12 speed Shimano rings as well as many other aftermarket branded chainrings.
Wing Dings can be purchased. These are optional and transition between the chainring and spider.
GRX Spider: Compatible with Shimano’s GRX chainrings! Allows you to swap chainrings from a GRX crankset. Supplied with 8 chainring bolts that fit this spider.
110×5: A spider for road and gravel bikes and chainrings. Can be used 1x or 2x. Mount 1x chainrings on the outside position or 2x on both positions.
*Compatible with Praxis 48×32 tooth sub compact chainrings.
130×5: An oldie but a goodie. Some folks are still using 130×5 chainring or 130×5 Gates belt drive… this is the spider for that!
144×5 Version 2: A spider for track/fixie bikes and chainrings. This spider has a conventional chainring mounting interface and uses standard chainring bolts (not included). Features extra material for maximal strength and stiffness.
See this Instagram post for more visuals of the cranks š
***Fixed gears put forward and backward rotational stress on the spider. For this reason the 144×5 spiders are installed onto spindles using a high strength retaining compound which removes play from the system.
2XR Chainrings (Direct Mount)
Chainring bolts be damned! Direct mount chainrings don’t require all the loose bits and pieces. Instead, attach cleanly to the 2XR Spindle with no hardware!
