Cresswell_d Posted February 20, 2011 Report Share Posted February 20, 2011 Hi all! I got a limey 1 of a friend a couple of days ago. Ive just started to build it up with parts from my other bike. (t-rex) The problem is the chain-ring is is hitting the frame has anyone had this had the same problem? The problem is either: My b.b is too small. (I've measured it and its about 127mm.) or, My crank set up is too big. (Ive got a 20 tooth chain-ring on a threaded bash ring.) Can any one help me please Thanks Darren Quote Link to comment Share on other sites More sharing options...

Cresswell_d Posted February 20, 2011 Author Report Share Posted February 20, 2011 (edited) What cranks, bro? Echo, square taper. Edit: They are old though. Edited February 20, 2011 by Cresswell_d Quote Link to comment Share on other sites More sharing options...
Revolver Posted February 20, 2011 Report Share Posted February 20, 2011 Trouble is, 127mm bb is the longest BB, so really you could only fix it the other way, get a smaller sprocket on the front. Quote Link to comment Share on other sites More sharing options...

I run a hope pro 2 on the back and that is a 15 tooth. Do I need a 18 on front or do I need even smaller? If I do need smaller what is the idea ratio?

Revolver Posted February 20, 2011 Report Share Posted February 20, 2011 20 15? Is that not too hard? 18:15 is normal, or 18:16. Quote Link to comment Share on other sites More sharing options...

Krisboats Posted February 21, 2011 Report Share Posted February 21, 2011 well i have 18:12 but it will be to light for you i think He rides a big wheeled bike though. I run 18:15 on my limey with a 128 and trialtechs and i have loads of room. To remove your cog you'll realistically need a vice. Quote Link to comment Share on other sites More sharing options...
