Swap Campagnolo Pista 175 chainset for 165

[flash]

I’m trying to swap Campagnolo Pista 175 chainset for 165, it's the rarer 151 bcd set and I have a fairly tired 50t chainring I can include.
Or 165 track chainset wanted

[bmx dude]

-would a 42 toothed -as- ring foit
as i have one so wont need yours

 

[flash]

Thanks, mine are the fluted ones, but I'm not keen on your TA ones, I'm hoping for Campag or Stronglight

 

[bmx dude]

hello

i have some 170's like in the pic -campag strada
and 2 52 toothed rings

for swpasies,

i need some self extracting crank bolts

and a campy 68 -108ishmm bb

 

[flash]

Sorry, I'm after 165mm, as I am building a race to work fixed bike and 165's clear the pavements when I cut down inside traffic, 170's don't, plus I have a bit of toe overlap, so the shorter the cranks the bette. If I sell the others you'll get 1st refusal.
