I currently have shimano M590 deore cranks on my Meta, Never really use the big ring... i have taken a punt on a SLX bash guard to replace my big ring. Will it just fit? Also i am using a MRP triple chain device, can this now go? Will i need anything else, like a stinger or such device?
Thanks,
Andy
Sorry to be the one to give you the bad news, but the Shimano SLX M665 bash won't "just fit" your M590 cranks (or any other cranks except the specially designed M665 ones for that matter!). Although the BCD of 104 is the same, the inside diameter of the bash is slightly smaller than a standard outer chainring. You can make it fit, but you'll need to file about 1mm off the bash where each of the spider arms fit.
You'll also need longer chainring bolts as the bash is significantly wider than an outer chainring.
Can't comment on the chain devices - never found the need for one meself if everything else is set up properly - ie. chain right length, medium cage RD, double FD, properly matched chainrings, and correct chainline...
ah! thats rubbish. Oh well.
I did something similar to my 456 but it already had SLX cranks. I did however just use the front triple stuff and wound the H limit screw in works fine.
Not saying you can't convert a triple to a double - done it myself and so have plenty others on here... its just that the M665 bash wont fit your cranks without a bit of filing - its specifically made for the M665 cranks. Any aftermarket bash like E-13, raceface etc. will fit your M590 cranks fine, and look a whole lot better than the Shimano one 😉
Ah ok cheers dude, I'll look into that.
anyone know anywhere having a sale on bashguards that will fit? 😉
ha ha... didn't fit... up for grabs in for sale section. 🙁
