LTWOO RX / R9 Disc 2x12s / 2x11s Road Hydraulic Disc Brake Groupset, 6 kit, Benchmark R7170 R8170
Groupset
The reviewer discusses the LTWOO (referred to as 'L2' or 'L2 group set') R9 disc groupset, which they state costs 108 quid on AliExpress. They explain that while cheaper groupsets like this are rarely as good as Shimano equivalents out of the box, with specific tweaks they can come incredibly close to Shimano levels of performance. The video is dedicated to sharing tips for improving the performance of this and similar budget groupsets. The tips cover mechanical shifting, cable routing, component wear, shifter rattle, and the specific process for bleeding the hydraulic brakes, including unique features like a grub screw on the brake lever. The reviewer also mentions that newer LTWOO groupsets have a tension adjustment screw on the front derailleur.
AI Summary
Pros
- Can come incredibly close to Shimano levels of performance with a few tweaks.
- Very low cost (108 quid on AliExpress).
- Uses mineral oil for brakes (not DOT fluid).
+2 more
Cons
- Out of the box, it is rarely as good as Shimano equivalents.
- Shifting can feel vague or mushy compared to Shimano due to tolerances and return springs.

SENSAH EMPIRE HRD 2x11s Road Bike Hydraulic Disc Brake Front Derailleur Rear Derailleur Carbon Shifter Bike Parts
Groupset
The reviewer mentions the Sensah brand several times throughout the video, but does not specifically discuss the 'SENSAH EMPIRE HRD 2x11s Road Bike Hydraulic Disc Brake Front Derailleur Rear Derailleur Carbon Shifter Bike Parts' as a complete, named group set. They refer to Sensah group sets in general, sharing tips applicable to them and other cheaper groupsets from brands like LTwoo. Specific mentions include that Sensah shifters can rattle, that Sensah hydraulic groupsets use mineral oil, that the bleed port on Sensah shifters is recessed and at a funny angle, and that Sensah front derailleurs lack a built-in tension adjustment screw.
AI Summary
Cons
- The reviewer states that Sensah shifters can rattle, a common issue with cheaper shifters.
- They mention that the bleed port on the Sensah shifter is recessed quite far and at a funny angle, making bleeding trickier.
- They note that Sensah front derailleurs do not have a built-in tension adjustment screw, requiring an inline barrel adjuster on the cable run.

QUICK PRO GR:ONE Carbon GRAVEL Bike FRAMESET
Frame
The reviewer built their dream gravel bike using the QUICK PRO GR:ONE frameset. They discuss several features and experiences with it. They note the seat post cutout provides noticeable flex and contributes to a comfortable ride at the rear. They mention the frame's tire clearance, stating the 44mm Tufo Thunderos inflate to about 46.5mm, which is near the maximum the frame can take, and express a slight desire for the option of wider tires. A significant initial issue was the lack of a zero-offset seatpost option, which they later solved by installing a zero-offset seatpost from Quick's AR:ONE model, though it lacks the matching spread-tow weave and the compliance cutout. They praise the bike's overall ride quality, describing it as comfy, fun, fast, and a machine they want to spend all day on. The complete build, including this frameset, is noted to be lighter than comparable complete bikes in the same price range.
AI Summary
Pros
- The seat post cutout provides noticeable flex and contributes to rear comfort.
- The frame offers good tire clearance (accommodates ~46.5mm tires).
- The bike rides brilliantly and feels fast.
+3 more
Cons
- The reviewer's biggest initial issue was the lack of a zero-offset seatpost option from the manufacturer.
- The available tire clearance, while good, leaves little room for wider tires, and the reviewer would have liked the option for more.
- The zero-offset seatpost they sourced as a solution (from the AR:ONE) does not match the frame's spread-tow weave finish and lacks the compliance cutout of the original.

Frame
The reviewer has used the Winspace T1600 as his primary race and training bike for approximately seven months, covering around 6,000 kilometers. He states the bike has been completely faultless, raced in Germany, the Netherlands, and the UK, and tested in a wind tunnel. The frame is described as extremely sensitive to wheel choice, and the integrated handlebars are highlighted as a significant source of aerodynamic gains. The build quality is praised as flawless, and the bike is noted for being extremely stiff. The reviewer mentions the bike comes as a frameset including the fork, handlebars, stem, and seat post, with the rest being bolt-ons. He also discusses the bike's geometry, noting the XL size has a longer top tube than expected.
