SRAM’s newest household of Eagle Transmission derailleurs hyped their sturdiness, however nothing is indestructible, and MRP thinks their new Cage Guard is the right insurance coverage coverage. Positive, it’s just a bit $30 piece of engineered plastic. However MRP is aware of a factor or two about conserving mountain bike drivetrains secure. And primarily based on the dents & gouges in my very own Transmission derailleur after only a half a 12 months of using, I really feel like mine might use a bit of additional safety…
MRP Cage Guard protects SRAM Transmission derailleurs
MRP has been within the enterprise of making bash-guards and low-friction sliders to guard our delicate drivetrain, actually because the beginning of technical mountain bike using took maintain within the Nineties. So seeing them determine to make a bash guard for a number of the costliest mountain bike derailleurs ever mass-produced appears fairly logical to me.
Machined in-house in Grand Junction, Colorado from sturdy & slippery Delrin thermoplastic, MRP created the 8g Cage Guard “to guard your SRAM T-Sort derailleur pulley cage from expensive harm brought on by rocks and particles“.
MRP says the brand new Cage Guard does double-duty of first stopping influence harm, and secondly of conserving your alloy cage from snagging when it hits a pointy or particularly abrasive rock.
Bounce off, and glide over rocks. As a result of in the end, limiting cage harm ensures the most effective shifting efficiency out of your premium SRAM Transmission.
Do you really want a bash guard in your SRAM MTB Transmission Derailleur?
Look, making a derailleur that works with a 10-52T unfold is all the time going to imply a protracted cage hanging down inside attain of trailside rocks. I do know an enormous a part of SRAM’s newest direct-mount Eagle T-Sort Transmission derailleurs was simpler serviceability. And the spin-off cage trick actually makes changing a cage quicker & simpler, that’s if in case you have a spare mendacity round. However these large angular cages do appear to stay out greater than even the earlier technology of Eagle derailleurs, making them extra susceptible low-hanging-fruit for hungry rocks.
Positive, the brand new T-type design means you possibly can simply exchange the quick-release alloy GX cage for round $100, a shiner alloy XX cage for about $150, or the flamboyant carbon XX SL cage for $200. However which means the most affordable substitute Transmission cage will nonetheless value you greater than 3x the value of the MRP Cage Guard. So, perhaps with $30 of Cage Guard prevention, it’ll by no means come to that.
Sure, it’s perhaps debatable whether or not 8g of plastic is basically going to stop a well-placed rock strike from killing your derailleur cage. Nevertheless it actually gained’t damage, proper?
I can say that I’ve hit a whole lot of rocks, bashing my path & enduro bikes by way of rock gardens. And I additionally fondly bear in mind greater than twenty years of bashing crankarms and chainrings onto rocks with MRP guards defending me.

This new little Delrin plastic MRP Cage Guard sells for $29.95, immediately from Mountain Racing Merchandise. And sure, that’s a fairly costly piece of plastic, however it’s so much cheaper than any substitute T-type derailleur cage.
