I’m putting together a new bike and got a old Diamant frame off this site.
The seller lied and did not include BB as he said he would. http://www.fixed.org.au/forums/f5/diamant-elite-57cm-sq-track-frame-**price-dropped-9629/
I installed a Shimano 110mm spindle square taper to go with some nice Sugino Mighty cranks I also bought.
Problem is I think even before I put a cog on the rear wheel that this chainline is going to be very ‘out’
See pics attached to show how far cranks sit from BB on the spindle but also there is only about 4mm clearance from chainring to rear stay.
I know that shimano BB comes in a 107mm, would it be worth exchanging it to bring it in 1.5mm each side?
Maybe I should get another brand BB so the cranks fit up the spindle further?
There were a couple of companies over the world with the Brand Name Diamant including the east germans. The east germans seem to be slightly larger than 26.4 ISO
The variables you have to work with here Azz
The rear chain line
a. different hub or different rear cog . A different cog brand can change rear chain line by a mm or so .
front chain line
a. different crank
b. different axle in terms of length
c.different axle in terms of taper ( the crank will sit differently on Jis vs iso - dodgy though)
d. bottom bracket with some adjustment in it that is a phil woods
I personally think phil woods is the way to go. You have about 5 mm adjustment in them and if you had bought one there would be no problem now. That is unless you like collecting a pile of different axles
Alright lets start from the beginning.
The cups that you have are too small for the head tube.
Now what is the internal diameter of the upper head tube measured accurately and what is the diameter and type of steerer tube. With that information you should be able to work out what will fit
^ you’re being extremely helpful but can you please show me where there is a list of headset cups that are 1-1.5mm larger than a standard 1" threaded one?
Because that’s what I need.
I am not being a smartarse I do appreciate your help but I’ve been to 5 shops, all over the net and come up with nothing.
