So apparently aheadset's zerostack headset didn't fit on my 727tr headtube . The thing looked like it fit , but it wasn't going down all the way . Here's the specs of the aheadsets's Zerostack Headset:
size 1 1/8"
bearing 5/32 Ball
top stack height 10mm
bottom stack height 4.5mm
So to my understanding another website is stating that FSA's ZS3 headset is the only headset that will suite the 725/727tr frames. Here is it's specs:
TH brand 36/45 degree Micro Angular Contact Bearings (blue seal)
7075 aluminum crown race
Laser etched FSA aluminum top cap
Stack Height* - 9.8 + 3.3 = 13.1mm
Black anodized finish
Weight - 80 grams (1 1/8")
Now can anybody help me ? I just wanna start ridinggggg . Thanks !
