As above,is it a straight swop or do i need longer/shorter chainring bolts?
Cheers.
E13s used come with bolts in the past, dunno if the newer ones do. Don't thinkt he standard Shimano bolts will work.
A bit off-topic, but have you already bought the E13 bash? If not, I have a brand new, still packaged black one you can have for £30 posted if you like?
Yep,already bought a 2nd hand one.No bolts with it hence the query.
From memory I had to use washers with the standard Shimano double n bash ones.
Having gone this route (and back again - but that's another story - see below) I can say its pretty much a straight swap. The E-13 Turbo is about the same thickness as the SLX bash, so if the bolts you have at the moment are long enough for the SLX, they'll be fine on the E-13. Standard SLX chainring bolts are 8mm long, and the ones that come with the M665 double & bash are 12mm long. So, as long as you have the 12mm ones you'll be OK. Even if you don't, a new E-13 Turbo will come with longer chainring [i]nuts[/i] - same effect, its all about having enough thread engaged between the bolt & nut despite the greater thickness of the bash ring over a standard chainring - so you either use longer than standard bolts, or standard bolts with longer nuts.
Just one thing to watch out for...
Although the SLX bash and the E-13 are both the same 104 BCD, the inside diameter of the SLX bash is smaller. The Shimano SLX M665 Double cranks have shortened crank arm spiders to match this, so if you then fit the E-13 to them there will be a small (only an mm or so) gap between the inside edge of the bash and the lugs on the crank arms its supposed to sit on. This shouldn't normally be a problem, as the bash is still held firmly by the chainring bolts. But, I found after a few good hard clunks on logs, the plastic bash split around each of the chainring bolts on my E-13. Had no such problem with the original SLX bash as it was both held by the chainring bolts, and supported on the crankarm spider's 'lugs'. For that reason alone, I changed back to the SLX bash, despite it being so much more ugly than the E-13.
Note: If fitting the E-13 to a SLX M660 triple, XT M770, Deore or pretty much anything other than the modified SLX M665 double, you don't get this problem, and the E-13 bash sits snugly on the crankarm lugs.
Sorry - long answer to a simple question, but having been thru this myself I thought I'd share my experiences...
Cool.Thanks for that.
If they don't work get some RaceFace poly bolts for about £5 they work.
