Lil Help Needed Here

[DrDaveTampa]

^^4 bolt mine is 5 bolt

i was going to jump on that L side crank that DrDave posted that would be perfect(and cheapest)

i really want to keep same gearing those rings much shorter gears (44t/32t/22t) than mine

 

[DrDaveTampa]

Haha it's riveted anyway. The fake bolts had me going there

The other thing about that first one is, what to do about the black chainring. I still haven't found a great way to de-anodize stuff other than sanding the crap out of it; EZ off doesn't do a thing for me, and I bought the cheapest crap I could find

DrDave

mentions EZoff but also 2 other chemicals

Spa Cycles in the UK carry a full range of 94/58pcd rings from TA.

Ugh
Sorry, more help needed
(I don’t have a crank puller and after days of trying to adjust rear mech….I took to bike shop to have both done)
So shop says
That granny gear 24t and outer gear 46t will work
But the middle 36t one will not despite the correct BCD
Explained to me(and I saw the minor difference) that the BlackSpire chain ring has 2 lips on either side instead of 1 lip and a ‘ramp’ on inner side
Ring for single speed (per say)
“Front mech (XT pull down) wouldn’t shift out of middle ring”
Can anyone confirm ?
These are best pix I found to explain ……

 

[89RingleAddict]

Lip
90 degree cut
(This is on both sides of the middle ring in question)

 

[89RingleAddict]

Ramp (needed per shop)

 

[89RingleAddict]

Like I said I saw/felt the difference
But after 30mins with tech, he got that this is 30yr old bike and limited options available to keep gearing
He will try to install and shift and report back to me

Any opinions?
Thanks again all
