Jonesy Posted October 7, 2015 Posted October 7, 2015 Hi. I can't seem to find locally, a crankset with a 48t large ring. This is for my mtb (carbon frame and fork, 38c tyres) which I use as a commuter/cyclocross, so I need the higher gearing. Does anyone know where I could get one locally?? Better still, larger rings for my XT crankset ? I've heard about fitting a road crank but is that a good idea? I know there will be some mods, but is there anyone out there that can help with the technicalities? CRC has Deore/SLX cranks with 26,36,48t . Should I save a whole lot of grief and just get one of those? Thanks
Sepia Posted October 7, 2015 Posted October 7, 2015 I used to have a 48T lying about for my old commuter.I will have a look. Will it fit the frame though? I have a spare SLX crank which used to go with this chain ring.
Jonesy Posted October 7, 2015 Author Posted October 7, 2015 Hi Sepia Thanks will appreciate that. A 3x should stand out from the frame more so it shouldn't be a problem. Will eagerly await your reply. Thanks Cheers
Mongoose! Posted October 7, 2015 Posted October 7, 2015 I tried it once. A road crank (external BB) on a mtb frame (26" hard tail) Did not work. Chain stays of a mtb frame comes out wider than a road frame causing the crank arms to hit the chain stays / could not even rotate once...
xcd Posted October 7, 2015 Posted October 7, 2015 You might have problems fitting a road crank as the arms do not have as much off set and thus less clearance between the chain stay and crank arms.I have tried it with a Sram crank.The clearance was only about 2mm
brumby Posted October 7, 2015 Posted October 7, 2015 I have the Deore 48,36, 26 crankset from CRC. Really nice crankset and well worth the money.Got mine about 3 months ago . Price has gone up by about R300 since then.

Thanks CheersThe crank I have is SLX with Shimano rings size 48-36-26. As said, used it on my old touring bike and it does not fit my current bike as the 48t catches on the chainstay.

Would you like to sell that to me if it works on my Silverback Storm?

Price has gone up by about R300 since then.Hi Brumby How long did it take to arrive? And what bike is it on ? Don't understand why no one here seems to have one.
Sepia Posted October 7, 2015 Posted October 7, 2015 What is your current bike? Would you like to sell that to me if it works on my Silverback Storm?I used it on Trance and it was the biz. Does not fit at all on a Superfly. I really liked it very much so kept it for use on another bike. I too don't understand why they are not used more often. Great for commuting IMO. 9sp though.
brumby Posted October 7, 2015 Posted October 7, 2015 Took 3 days to arrive from CRC. I've put it on a Giant Escape which has a 135mm rear axle width (same as a mountain bike) .

brumby Posted October 7, 2015 Posted October 7, 2015 Stock front derailleur - no idea what it is. Alivio shifters, Deore rear derailleur and cassette.
Sepia Posted October 7, 2015 Posted October 7, 2015 I would be interested in buying if it's in good conditionWhy not just take the 48T big ring?
Jonesy Posted October 7, 2015 Author Posted October 7, 2015 Why not just take the 48T big ring?Would love to, but I don't think the ring will fit my crank even though it's 104 BCD.Same BCD apparently does mean compatibility. This is complicated.....
