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 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.

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.
