RaceFace Crank Boot Protectors

They perfectly fit on my RaceFace and SRAM cranks!

A little big for my crank set but look sweet!

The Race Face crank boot protectors are a simple yet superbly effective solution for protecting a mountain bike crank arm from damage. What you get are molded rubber-like covers that are nice and thick, offering protection from scratches and impact that clear-type "skins" cannot match. Installation is as easy as removing your pedals, slipping the boots on, then re-installing your pedals. I have used these on SRAM/Truvative X9 and X0 cranksets and they fit perfectly.Two things to note: first of all, there is no mention of a specific left or right side on the products, and you would assume that all crank arms are identical in shape at the ends, but if the Race Face boots don't wuite slip all the way onto your crank arm, swap the left boot for the right boot and they should be centered and all the way on (I experienced this with both cranks I tested). Second note - upon reading other reviews here, some say they fit other brand/model cranks, some say they don't - but if you take a look at the Race Face website, they actually have a list of what cranks they know are compatible:(from Race Face website)Fits:Race Face:Next/Next SLSixcRespondSram:XXXONoirFSA:GravityGravity LiteShimano:SaintNotice though that my X9 and X0 crankset is not listed - yet they fit perfectly - so if you do not have any of the cranksets listed the only way you can find out is to try them. Not that big of a deal to experiment since it's only $9 a pair, which is a value considering you are protecting your $250-up crankset from rock strikes and damage.

Seems like a good product just not for Shimano fc-m8120

They do prevent damage and scrapes to your crank arms. They also soften the blow from rocks and boulders that make you cringe. It's just a little added protection if you care about the cosmetics of your bike.

The boot itself is a snug fit for SRAM Red crank tips. However, the spindle holes don’t like up exactly. If you remove a small amount of plastic from the top of the outer hole, you’ll get an excellent fit.The inside hole for the hex driver doesn’t line up perfectly, but it’s close enough that you can get the tool in there if you lightly wedge the plastic to the side. I suppose you could enlarge the hole a bit, but that doesn’t seem necessary.I’m surprised SRAM doesn’t make boots for their road cranks since they are used for gravel, but this is a totally workable solution.

RaceFace makes three different boot covers for the following cranks types. I did the resarch to make this east for your. Take a few minutes to read this information.NOTE: When ordering these boot covers you will receive the Carbon Crank Boots (size medium). Read on for details.1. NEXT SL G4 CRANK BOOTSThese are built specifically for the Next SL G4 cranks. Also, these crank boot covers have the word “NEXT” printed on them, whereas the other boots only have RaceFace on them.2. CARBON CRANK BOOTS (this is the version you will receive if ordering here).This is the MEDIUM SIZE boot cover.The carbon crank boot covers are compatible with:- Next SL Cinch (G3)- Sixc Cinch- Chester- Respond- Next/Next SL (24mm Spindle)- Sixc (24mm Spindle)- Also, most other popular carbon MTB cranks and assorted alloy DH cranksThe carbon crank boots are sold under the following part numbers based on color selection. The part number will be printed on a sticker affixed to the package you receive so you can verify what you received.A10066GRY = greyA10066BLU = blueA10066RED = redA10066TURQ = turquoiseA10066YEL = yellowA10066GRN = greenA10066PIN = pinkA10066ORA = orangA10066BLK = black3.

However, they are all made from the same material, so I am giving five stars for quality of product.I installed the Alloy Crank Boots (size small) on my Stumpjumper which has Aeffect cranks. They fit good. The only thing I noticed is that the hole were you put your Allen key is a little off, but the boot cover is playable enough that I was able to install it with no problem.

Very high quality, but they didn’t fit my bike because the vendors description sucked

after exhausting searches on google which only brought up crank boots for the praxis carbon version i decided to give these a go. For the price it was worth the risk!Not a perfect fit and getting allen key into pedal axle to tighten pedal from behind isn't the easiest but once they are on, they are on and do what they are designed to do.Only wish i fitted em sooner.

Mon vtt et gravel.

Ottima soluzione per proteggere le pedivelle, sopratutto se si percorrono tratti scassati; la Taglia delle protezioni è M e le ho installata su pedivelle SRAM X1.Unica pecca il colore, l'immagine indica verde fluo, in realtà è un verde oliva opaco; contento comunque in quanto riprede il verde del telaio della mia MTB.

Son imprescindibles para proteger las bielas de mtb

Sitzen leider auf den Kurbeln zu locker und schlackern daher hin und her.Etwas enger und aus einem mehr gummiartige Material wäre besser gewesen!
