Pros
  • 2 bolts, 2 nuts and 2 washers for Thomson seatpost
Cons
  • No instructions

Pros
  • Only 12 grams
Cons
  • The list is getting long.

They are more or less identical to the original in size and shape. Just in case, I used a blue fixative and tightened to 5.4nm. If anything changes I will update the review. Shipping was damn fast but I made sure to…
