Rated 4.8 out of 5 by 4 reviewers.
Rated 5 out of 5 by Does what it is supposed to Great bash guard - fits my Shimano Deore XT FC-M785 perfectly, extra long bolts needed to fit this were also supplied. Easy enough to fit, would have been easier to fit had I split and removed the chain first but managed to do it without splitting chain, once fitted had to make a minor adjustment to my deraillleur. 05 September 2014
Rated 5 out of 5 by Superb piece of kit! Super lite and easy to fit. Does exactly what it's meant to do and looks well on bike. 09 April 2014
Rated 4 out of 5 by Indestructible Not only is this a beautifully machined piece of Alloy from Blackspire but its simplicity is its selling point. It bolts straight onto your spider via the same 4 boltholes as the chainrings with larger bolts provided. For something so 'big' its light as a feather. Available in custom tooth sizes. 23 March 2014
Rated 5 out of 5 by good quality Bash guard and easy to fit as all parts needed are in the kit. not many options around for 120 bcd 2x10 bash guards , but this is perfect and although a bit pricey its a very good add on for your sram XO crank set. 14 December 2013

Answer: 
This bashguard will not work with SRAM’s 2x10 S2210 chainset due to the spider fitting design. There is no mounting position for a bash unless you replace the largest chainring. Which would limit your options for a suitable chainring size to be ran (as you would only have a choice of the smallest chainring position.)

Answer: 
Depends on the number of bolts on the spider (where nuts go thru crank to chainrings) and the bolt circle they make up. Its meant to fit most new Sram/Truvativ rigs (with the appropriate bolt circle sizes) and Shimano XT. If in doubt ask your LBS.

Answer: 
I have the XT FC-M785 Double Crankset and you will be pleased to know this bash guard fits like a glove as I have one on mine. It was designed specifically for the XT double groupset and has a variety of tooth options (make sure you get the right size). All you have to do is swap out the 4 bolts on the large chain ring for those supplied with the Blackspire guard. This is a quality piece of kit that will last for years. With the use of a Shadow + rear mech - it should negate the need for a chain device.

Answer: 
Yes it will - I have one on mine. Blackspire Defender 38t. Please see attached photo for clarification. Make sure you get correct tooth size as there are several. This is only made specifically for new XT groupsets with 104mm cbd. No rock or bashguard or chain device just a Shadow + rear mech.

Will this fit a SRAM X7 Double Chainset

I have a X7 with 28/42 rings. The spacings are 120 and in theory this is the correct size, but will it definitely fit/attach without any issues?

Answer: 
The 120mm Bolt Circle Diameter (B.C.D.) bash guard is the required sizing for the SRAM X line of crankset's. The 42tooth variant will be required to protect the chainring's on your crankset.

Item: 'sku344174' (120mm, Black, 42t) is the recommended product for protecting the chainring's sufficiently.

Answers

Answer: 
This is really a 2 x 10 drive train bash guard ring. Its main purpose was for new XT cranksets with 120mm bcd. The largest size is 42 teeth so if your M590 has a 120mm bcd - it may fit but I suspect you may have to remove the largest ring - thats a huge ring for that bike! This is not a chain ring just a guard.

Answer: 
This bash guard should fit fine, although the possibility of needing slightly longer chainring bolts for the outer chainring is quite likely.
