I bought a £700 second hand Trek Domane and upgraded it to see how good it could really get.

RYET Bicycle Saddle Ultralight Racing Bike Full Carbon Bike Seating Saddles Road Sports Cushion Cycling Accessories
Created: February 16, 2026The reviewer mentions swapping the stock saddle for a 'Riot saddle'. They state they could not use a super light carbon saddle due to the bike's clamping mechanism not supporting oval carbon rails, so they had to use a steel-railed saddle instead. They describe it as 'a bit heavy' but found it 'really comfortable riding'.
AI-Summary
Pros
- The reviewer found it really comfortable for riding.
Cons
- The saddle is described as 'a bit heavy'.
- The reviewer could not use a super light carbon saddle as intended because the bike's clamping mechanism does not support oval carbon rails, forcing them to use a steel-railed version.
Key Points
- It is a steel-railed saddle.
- It replaced a stock saddle the reviewer disliked.
- The bike's clamping mechanism prevented the use of a lighter carbon saddle with oval rails.

They state they are swapping the bike's original heavy, rusty skewers for these 'nice lightweight titanium AliExpress ones.'

- Titanium construction
Cons
- Not the lightest option available (they were replaced on another bike for lighter ones)
Key Points
- Brand is ZTTO
- Source is AliExpress
- Material is titanium
- They are lightweight
