Grebel Posted March 22, 2011 Posted March 22, 2011 Hey RodTi, Have you considered these... Race Face SS
The Drongo Posted March 22, 2011 Posted March 22, 2011 Thanks for all the info Hubbers! But thought I'd revive this now, since the build is imminent! The LX cranks I bought, have been lying in a box, unopened until the past weekend.On taking them out - I had one of those "hmmmm" moments... Read through all of the above again - but cannot get my head around this - can the crank be successfully converted to a SS setup? In the pic below - I've only noticed now how the 'spindle-arms' [what would the correct term be?] - unlike in the XTR range, don't continue up to the outer blade... The big blade bolts into the recess on top, and the middle blade bolts in from the back - but all of it being 'next to' the spindle arm, if that makes sense... Surely if the big blade is removed from the picture, it will leave a very-visible recess where it was clamping in to... More importantly, I'm wondering whether removing the big blade won't reduce the structural integrity of where the middle blade clamps in to...? Wait - I've just looked at the pic closely again - I actually cannot see how this could be done? I will have to go and look properly tonight again... Your thoughts will obviously be appreciated... RodTi Either use a bashguard - Raceface (bless their liquidated heart) did a nice light alu one. Or get shorter bolts from SS. You wont get away with the 'step', but you WILL have less trouble finding chainrings for 104BCD. Although Blackspire do a 102 for XTR.I am running Raceface, with raceface bashguard and 36 ring. Deore are nice and strong too. In fact the Deore on my FS flexes less than the Raceface.
The Drongo Posted March 22, 2011 Posted March 22, 2011 Hey RodTi, Have you considered these... Race Face SS THAT - Be the bashguard. I reckon the Shimanos you have will flex less than the Rf's
RodTi Posted March 22, 2011 Author Posted March 22, 2011 Hey RodTi, Have you considered these... Race Face SS Hey Grebel - RaceFace is closing up shop, no? Nah - didn't want to invest in a SS-specific chainset until I was sure the bug had bitten properly, which is why I bought the LX set in the pic above - for only slightly more than 300 Souf Efrican ronts... Figured it could remain a back-up to my other crankset if the SS didn't grab me. Now I'm wondering whether it would be at all possible to convert it to one blade, and still have it look half-decent?
SteveS Posted March 22, 2011 Posted March 22, 2011 Hi RodTi Got your pm. Attached find a pic of the LX cranks when they were still on my 26" SS (dont know the model number). My LBS made spacers out of a stuffed big chainring. This was a few years ago before the short chainring bolts became available. I am sure you could just do the same conversion as Deanbean

So the recess remains (where the big blade used to connect) - and then simply leave the middle blade as is (and remove the inner)? The middle will still sit fine in the absence of the big blade? And why the bashgaurd? For aesthetic purposes only (in light of my particular crankset), or for the protection etc? The Raceface will fit the Shimano, yes?
whistler Posted March 22, 2011 Posted March 22, 2011 Mount the middle blade in the big blade's position. That's what I did with an older type Shimano LX crank and it works... beautifully...

I have heard that could be the case... Stick around for a going out of business sale!! Seeing as you only paid 300 SER, I reckon you got a bargain! Drongo had a good point about the bash ring. Not sure where to get it separately though.

The bashguard, besides looking Reealy Titty, will take the space of the large chainring, give your chain (and leg) some proteshun, and you won't have to faf with 'shorter' bolts or hacking up an old chainring. Which in itself is not a shabby idea, it's just that I am very keen to: A: See your build Built, and B: Get you in the saddle. ......Finally.

I am sure you could just do the same conversion as Deanbean Thanks Steve! Yes - I'm relieved to see all is not lost with me - I was thinking about that as an option... Did you simply take a hacksaw (etc.) to it? Am I correct in that the black parts on the tips is what simply remains of the big blade - and the middle blade still locks in from behind?
divernick Posted March 22, 2011 Posted March 22, 2011 Rod Ti, 1. Remove all rings from the new cranks.2. Obtain short chainring bolts3. Attach new SS ring on the INSIDE of the crank spider4. Align SS sprocket on the freewheel to get a nice chainline using washers or whatever spacer method.5. Post pics!

I know, I know - you'd be forgiven for thinking I was building a friggin' gauno-powered Enterprise or something, instead of a SS, with the amount of time I've been faffing around! [in my defence - with the arrival of the little one a month ago - time has been rather scarce!] I will pop up pics of the frame in the week - she's going to see some TLC first! Back to the question: Will keep the bashgaurd option in mind - get what you mean now with regards to it 'replacing' the big blade... Will see what else I the Hub can come up with - appears to be some good options so far!
divernick Posted March 22, 2011 Posted March 22, 2011 Good luck with the build, you're gonna love riding it.What cog / chainring ratio are you gonna run? I am loving my 38/20 at the moment.
RodTi Posted March 22, 2011 Author Posted March 22, 2011 Mount the middle blade in the big blade's position. That's what I did with an older type Shimano LX crank and it works... beautifully... Oooohhh. And how did you do this? Any chance of some pics?
