wheelz Posted September 4, 2008 Share Might be a stupid question, but anyways why cant you use a road crankset on a mtb?? the crank lengths are the same, just the chainring sizers differ, but surley you can get a chainring in whatever mtb size you want,eg 44-32 Link to comment Share on other sites More sharing options...

TNT1 Posted September 4, 2008 Share Different Bolting circle. Yeah, but the road carnkset would fit the mtb BB? Yes? How about a compact road with a 33/50 or so? If I don't want/need a triple on my mtb? Link to comment Share on other sites More sharing options...
wheelz Posted September 4, 2008 Share Different Bolting circle. yes but cant you get smaller(eg 33-42) road chainrings? im just thinking aloud Link to comment Share on other sites More sharing options...
Ox_Wagon Posted September 4, 2008 Share On BB first. It will fit if the cranks use that same BB (Square tape/octalink/isis etc) BUT the MTB BB axel may be wider to accommodate a triple crank set which will increasing the Q-factor.<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" />The BCD determines the smallest chain ring that you can fit. To quote Http://www.sheldonbrown.com/harris/chainrings.htmlCampy road = 135 BCD = 39Shimano road = 130 BCD = 38Road Compact, MTB STD (old type) = 110BCD = 33MTB Compact (on all new MTB, 4 arm) = 104 BCD = 32 (29)There is also ?supposed? to be a small difference between the spacing of the chain rings. Shimano recommends that you use their ?special? flatbar shifter instead of normal MTB shifter.http://cycle.shimano-eu.com/catalog/cycle/products/group.jsp?FOLDER%3C%3Efolder_id=2534374302049903&ASSORTMENT%3C%3East_id=1408474395181667&bmUID=1220548200443 The 2x9 MTB setup is a relatively old idea(Cannodale's coda cranks etc), but they fit a 29 instead of a 32. 29 are just very hard to find expecialy in ZA. http://www.chainreactioncycles.com/Models.aspx?ModelID=30179http://www.chainreactioncycles.com/Kits.aspx?ModelID=3345Ox_Wagon2008-09-04 11:12:28 Link to comment Share on other sites More sharing options...
Ox_Wagon Posted September 4, 2008 Share I have an old XT, 5 arm, 110 BCD crank that has a 46/38/24 on it. They came out standard with 46/36/24 . I am considering removing the granny and replacing the chainring and then using it as a road crankset. Ox_Wagon2008-09-04 11:02:49 Link to comment Share on other sites More sharing options...
Ox_Wagon Posted September 4, 2008 Share There is more?..<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> MTB chain stays widens faster and more to accommodate the larger tire so you will have to check if there is space to install a larger chain ring (clearance problems). As far as I c<?: prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />an remember it was one of the big reasons that everybody moved to the current Compact MTB cranks. Where is all that guys that say only girls ride compacts, they should explain the compact cranks on their MTBs. Link to comment Share on other sites More sharing options...
