DaveG40 Posted February 21, 2008 Report Share Posted February 21, 2008 Inside the b/b thread there doesn't seem to be anything about my frame. I bought it on Monday and need a new b/b fitted.In my noob thread someone mentioned it was a saracen x-ess / x-ile frame, circa 2001.Pic:I removed my cranks to find the l/h side is completely knackered - so after some hunting about i found 2 crank sets i like the look of and in my price range.The first is a suntour duro dirt which fits ISIS b/b's only... these look strong(er) than my second option and have a heavy duty guard.If i can fit an isis b/b i will buy the suntour duro cranks but if I cannot fit an isis b/b I have also found a standard square taper crank set. This is the m-ighty x single ring 33 tooth crank set. Can anyone help me out? Will i be able to fit an isis b/b or will i end up needing the m-ighty x 33 toother?Many ThanksDave Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted February 21, 2008 Report Share Posted February 21, 2008 If you are wanting to build this up bit by bit into a trials bike, then you can pick up a set of Middleburn cranks on here cheapish (I've bought 2 sets, £35 each) second hand.Both of the cranksets you've mentioned will be ok for a very short term fix, but are cheap and as such are made poorly/from worse materials.If you're looking to end up with something ridable, it's worth spending a touch more (it doesn't have to be a lot, I've just built a full bike for £130, including Pro II, Maggies, 'burns etc) in the long run Quote Link to comment Share on other sites More sharing options...
DaveG40 Posted February 21, 2008 Author Report Share Posted February 21, 2008 I'm not looking to make it into a trials bike. I just like this forum!My aim is to have a 9 speed commuter with this frame.Not going to be used for jumps etc - just for a bit of both road and off road use, i use underpasses and go over a couple of off road bits of terrain.On further inspection isis b/b's are far too expensive for me...Looks like i'll need a square taper replacement after all....Shame Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted February 21, 2008 Report Share Posted February 21, 2008 go square taper and get a un52 shimano model...It might be worth you checking out www.bikeradar.com ...they have an xc section that might be better suited to your questions....

Tomm Posted February 21, 2008 Report Share Posted February 21, 2008 If it's just for a normal mountain bike just get some deore hollowtechs. Cranks + rings + BB for £45, brand new. You won't get much better than that. http://www.chainreactioncycles.com/Models.aspx?ModelID=22924What's actually wrong with the bike at the moment? Why do you need both crank and a BB?

Why do you need both crank and a BB?ThanksWhen peddling the arm had play on the l/h side...I thought it was just the b/b but after removing the arm I found the square taper was ok on the outer side but on the inner side the square hole was worn and had started to weaken the metal making it head toward being a diamond shape instead - lolI think i have the same metal arm on my other saracen so maybe able to use that as a stop gap on a slightly worn b/b.Will that kit fit my bike?Dave Quote Link to comment Share on other sites More sharing options...
DaveG40 Posted February 21, 2008 Author Report Share Posted February 21, 2008 Also forgot to mention I'd rather run a single chain ring crank without a front derailleur as they are horrible for my trouser legs when they get caught!Sorry about all this - just wanna get it back on the road!

Tomm Posted February 21, 2008 Report Share Posted February 21, 2008 I'd be very surprised if the bottom bracket it actually damaged. BBs have steel axles so they're strong and they don't deform as quickly as the soft aluminium tapers on the crank. Just get a replacement left hand crank from somewhere and you'll be fine.By the sounds of it, neither of those other cranksets you're looking at are worth 'upgrading' to.
