Title: will these fit on a pair of twin pinch flight cranks?
Post by: griff on November 09, 2010, 11:53 PM
evening all

was mooching around the porkchop site and came across these
http://www.porkchopbmx.com/Chrome-plastic-crank-arm-caps-PAIR-2404.htm

anyone know if these will fit on my redline flight twin pinch cranks?
http://www.alansbmx.com/product_info.php?cPath=116_121&products_id=6700

love the cranks but not massively fond of the black bolts that came with them

if these won't fit any links to alternatives (chrome bolts?) would be appreciated

cheers

griff

If I remember correctly Redline cranks do not have a thread for the crank arm caps to screw into.

griff are they flush mounted black bolts that came with the cranks. if so, rub down the ends with some wet n dry and polish them.

you can get sets of chrome hardware from the US, I got some earlier this year, not cheap but they look the dogs  :daumenhoch:

thought as much - but would have been a bit cheaper than buying the hardware set! (those bolts look nice though bobbysam but aren't they for a single pinch crank?)

cheers

which bolts did you get with your twin pinch as there are at least two types?
the bolts in the link are for single pinch flights and are imperial thread i'm sure (correct me if i;m wrong anyone)
i'm pretty certain twin pinch bolts are metric (again correct me if i'm wrong)

in that case give them a polish as marc say, they come up a treat  :daumenhoch:

I bought them for single pinch, I didn't realise there was a difference, sorry mate :daumenhoch:
