About The SRAM Apex XPLR D1 12-Speed Medium Cage 44t Max Black Rear Derailleur
The SRAM Apex XPLR D1 is a cable-actuated 12-speed 1x rear derailleur for cassettes with a 44t large cog. It pairs a clutch and X-HORIZON parallelogram with a medium cage sized for gravel gearing.
It works with SRAM 12-speed mechanical Apex and Eagle shifters and SRAM 12-speed Flattop chains, and mounts to a standard derailleur hanger. Chain wrap capacity is 34t.
Who It's For
- Gravel and all-road riders building a 1x 12-speed mechanical drivetrain with a 44t cassette.
- Owners of Apex 12-speed mechanical shifters replacing a derailleur.
- Consider the Apex Eagle long cage if you want a 50t or 52t cassette, or an AXS model for wireless shifting.
What to Look For
- Chain: Uses a SRAM 12-speed Flattop chain, not an Eagle chain.
- Cassette: 44t largest cog; 34t chain wrap capacity.
- Shifter pull: SRAM X-Actuation 12-speed mechanical.
Key Features
Clutch. Controls chain tension so the chain stays on and quiet on rough surfaces.
X-HORIZON parallelogram. Horizontal-only movement that SRAM credits with preventing ghost shifts and lowering shift effort.
Cage Lock. Locks the cage forward for wheel changes and chain installation.
Medium cage. Sized for 44t cassettes rather than the 52t Eagle range, keeping the cage shorter for gravel.
Rider Intent Summary
- Biggest strengths: Mechanical 1x simplicity with a clutch and 44t range.
- Tradeoffs: Requires a Flattop chain; tops out at 44t.
- What makes it different: A mechanical gravel derailleur that uses road chain standards with mountain-style chain control.
Victory's Take
We fit the Apex XPLR on gravel bikes where the rider wants cable shifting they can service on the road. Victory Bicycle Studio can check chain and cassette pairing before install.

Frequently Asked Questions
Do you offer free shipping?
We do offer free shipping on non-bike orders over $100. We do not offer free shipping for bicycles unless it is a one time promotion. Generally, bike shipping will cost $150 and that covers just the shipping of the bike with no assembly. If you were to bring that bike to your local mechanic or bike store, you would pay them their assembly fee. If you choose our Professional Assembly option for $200, our service technicians would assemble the bike before shipping and then re-pack the bike safely for transit. When you receive the bike you would attach the front wheel, attach the seatpost/saddle, and raise the handlebars and clamp them. Those three items do have to be detached to minimize or eliminate the chance of damage in transit.
How much does shipping cost?
For orders of parts, accessories, apparel, etc. on orders under $100, shipping is a flat rate of $9.99. Regular bike shipping without assembly is $150, bike shipping with Professional Assembly is an additional $200 (so $350 in total which includes the $150 of regular shipping). Our White Glove Delivery option is $699 and that will cover the assembly of the bike and our White Glove Delivery partner delivering your dream bike to your front door, ready to ride!
How can I track my order?
When you place your online order, you will receive an instantaneous email update with your order number and order details, and shortly after, you will receive a follow up order email with the tracking number for your order. If you still need assistance with your order, feel free to email us at online@victorybicyclestudio.com and we will respond asap.
