Will a Profile BB fit modern Redline flights?
« on: March 28, 2006, 09:28 PM »
Alright guys, please let me know if the Profile BB pictured will fit the modern (2000's) Redline Flight cranks.

I think they are both 19mm. I prefer the Profile BB as they are chrome and will look better on my chrome TA resto.

Assistance appreciated as always.

Nope  :crazy2:

swap the bearings

-they dont fit as - a reline spindle is smaller than a profile chainring hole
-you have to file the spacer to get a profile chainring on.
-thats what i did.

Thanks Steve and Billy.

The seller of the Profile BB says they fit a 19mm spindle.

I have measured the Redline BB and its 19mm too. Also on amazon its says the chainwheel is 19mm, see the link below:

I think they should fit. But I could be wrong, as I am not an expert.

Cheers

I recently had to swop some flights over to profiles on a bike and I had to change everything over, the spindle was not compatible with different bearings  :(
