The long-awaited and extra inexpensive SRAM Eagle Mechanical Transmission is in any case right here, with each a inexpensive model concentrated on OEM spec and a extra top rate possibility for riders who prioritize simplicity and serviceability.
Many mountain motorcycle riders are enamored by means of AXS, UDH & T-type innovation – me amongst them. However some nonetheless would really like to mix the highlights of SRAM’s newest tech with the simplicity and affordability of a vintage mechanical shift setup.
Smartly, that wait is over.
Those 2 all-new mechanical shift SRAM Eagle 90 & Eagle 70 mountain motorcycle drivetrains ship the entire powerful and easy direct-mount guarantees of Transmission for a fragment of the cost. No Batteries required.

SRAM claimed their T-type MTB Transmissions delivered the very best mountain motorcycle shift. Now Eagle 90 & Eagle 70 each carry that very same efficiency to riders preferring mechanical simplicity over costlier wi-fi electronics.
The 2 new Eagle 90 and Eagle 70 Mechanical groupsets promise the similar painless setup & adjustment, common direct ‘Full Mount’ are compatible, complete transferring beneath load, and modular rebuildability as excellent or higher than SRAM’s most sensible digital transmissions. However now it comes at a a lot more inexpensive worth, and is solely as gentle for the important thing elements.
Plus, you’ll by no means have to bear in mind to rate your motorcycle.
SRAM has completed a forged process of transferring the course of mountain motorcycle drivetrains. First, with vast 1x Eagle as much as 520% vary. Then, the simplicity & interoperability of wi-fi digital AXS. And in any case, a regular the business would in fact get in the back of with the Common Derailleur Hanger that prepared the ground for his or her direct mount T-type Transmissions.
It’s been just about a decade since SRAM innovated with a mechanical shift crew. So, whilst the tempo of era marched on, should you didn’t need to rate batteries or didn’t have a large finances, you had been out of success.
Now, SRAM Eagle Mechanical in any case fills in that hole!
What’s new?

SRAM touts this because the first-ever mechanical groupset with out a derailleur hanger, due to their direct Complete Mount interface the usage of their UDH usual. That suggests the similar tricky and strong design since it’s bolted proper in your body. Setup is straightforward without having for adjustment screws for the reason that frame-derailleur-cassette interface is already outlined and the similar from motorcycle to motorcycle. Mix that with SRAM’s newest cassette ramp design and flattop T-type chain, and it additionally manner crisp transferring even beneath load.
Plus, the brand new Eagle 90 is claimed to be probably the most rebuildable derailleur ever…
Extra modular and rebuildable than ever!

When SRAM introduced their direct mount AXS Transmission, it promised each advanced sturdiness AND new modular development that may help you restore a derailleur that did wreck. We even broke that declare down in an in depth Patent Patrol tale.
Now with SRAM Eagle 90, that in any case involves fruition with a derailleur that may in reality be totally rebuilt. SRAM talks it up like this is usually a mountain motorcycle derailleur that would final a life-time.
The Eagle 90 mechanical derailleur can also be utterly damaged down – isolating out the direct mount B-knuckle, the P-knuckle that homes the take hold of, the parallelogram & its skid plates, the cage in different ranges of disassembly, and the entire bushings it rotates round. SRAM sells each and every of the ones user-replaceable portions in my opinion from $18-85 (20-93€ / £18-83). So, should you injury part of your derailleur or simply need to continuously provider it each and every season, it’s each simple to do and inexpensive.
Hooray!
The Eagle 70 isn’t just about as user-serviceable, however it nonetheless has replaceable skid plates. It makes use of a lower-tech drag-spring damper take hold of mechanism (more potent than the outdated SRAM drag-spring) that isn’t interchangeable. However you’ll be able to nonetheless substitute the remainder of a broken derailleur cage if want be.
Almost definitely quicker transferring than Eagle AXS?
Whilst the theory of transferring beneath load used to be a pleasant new function of T-Sort Transmission, it did require SRAM to decelerate transferring, essentially so ebikes beneath complete energy wouldn’t attempt to shift more than one gears immediately and most likely injury the chain, cassette, or each. That no doubt bugged numerous mountain bikers coming from the faster-shifting earlier technology of AXS.
Even supposing SRAM says they seemed on the numbers (as a result of AXS tracks shifts), with the outdated setup, 88% of all transferring used to be unmarried shift in common use, simply 9% a double shift, most effective 4% a triple shift, and a measly 1% looking to shift 4 gears immediately. (Please forgive SRAM’s rounding, no longer mine.) So with Eagle Mechanical, they determine they might make you satisfied about 96% of the time.
Eagle 90 2-click (l) & Eagle 70 Unmarried-Click on (r) shifters
Now, the brand new SRAM Eagle 90 & 70 Mechanical mountain motorcycle transmissions carry again rapid multi-shifts, no less than for non-ebikes. With 2 shifters to be had for each and every groupset, you’ll be able to select as much as two shifts at a time from the usual MTB shifter. Or there’s a separate eMTB-specific Unmarried Click on Shifter so you’ll be able to’t screw up, even transferring beneath complete energy from the ebike’s motor.
The brand new shifters additionally glance just a little larger/longer. That’s as a result of SRAM optimized the brand new format to take a seat nearer to the bar and to align your cables with Stealth-routed brake hoses for blank and direct cable routing. A facet receive advantages is shorter shift housing and lowered overall cable bend angles for higher shift efficiency general.
Only a word: new Eagle Mechanical transferring elements are NOT backward-compatible with earlier SRAM mountain motorcycle or dropbar shifters.
New quick alloy cranks, too
The brand new Eagle Mechanical teams upload their very own easy solid alloy cranks, adopting the rage of ever-shorter crank fingers. Eagle 90 gives cranks from 155-175mm, plus an eMTB-specific 150mm set. SRAM Eagle 90 options 8-bolt direct T-Sort chainrings, with stamped metal and machined alloy rings to be had.
Eagle 70 is just a little decrease tech (and with fewer duration choices) with 3-bolt direct T-Sort chainring mounting.
Each proportion chainring-mounted bashguards, the similar as with GX & X0 cranksets.

An important word this is that the brand new SRAM Eagle Mechanical Transmissions are extra inexpensive than anything else AXS, and they’re to be had now. Importantly to notice, all T-type Transmission elements also are cross-compatible. So if you are going to buy a motorcycle with Eagle 70 or improve your motorcycle with Eagle 90 these days, it’s good to nonetheless switch to a wi-fi setup with simply an AXS shifter & derailleur down the path.
There are necessarily 4 variants of the brand new SRAM Eagle Mechanical Transmission – 90 & 70 for mountain motorcycles and 90 & 70 for eMTBs. The variations simply come right down to cranks particular to particular person ebike motors and the eMTB shifters that permit just one shift at a time.
An Eagle 90 entire groupset sells for $670 / 730€ / £655, together with the brand new mechanical rear derailleur, mechanical shifter with a clamp, plus a crankset, GX chain & GX cassette. Get your personal backside bracket and new brakeset one after the other.
By itself, the brand new Eagle 90 mechanical derailleur prices $190 / 205€ / £185, the shifter is any other $50 / 55€/ £50, and the alloy crankset $155 / 170€ / £150.
You’ll see the Eagle 70 groupset most commonly already spec’d on entry-level efficiency mountain motorcycles, however you’ll be able to purchase the elements one after the other as smartly. Evaluating it to its more-expensive sibling, the brand new Eagle 70 mechanical derailleur prices $125 / 135€ / £120, the 70 shifter provides simply $30 / 35€/ £30, and the alloy Eagle 70 crankset any other $90 / 100€ / £90.
