OSPW
The reviewer discusses an AliExpress OSPW (Oversized Pulley Wheel) system, which is a generic or unbranded alternative to the Ceramic Speed OSPW. They installed it on a Shimano Dura-Ace 12-speed rear derailleur with an 11-speed chainring. They state the shifting is smooth, the transmission works smoothly and freely, and the part feels high quality and spins nicely.

ZTTO Ultimate 11/12 Speed Road Bike Cassette 11s 12s 11-28/30/32/34/36T ULT Sprocket Freewheel 112g~141g Road Gravel K7 HG
Cassette
The reviewer analyzes a super lightweight cassette from AliExpress, which is the ZTTO Ultimate model. They describe its unique two-piece construction, with the front sprockets milled from a single block of steel and the rear sprockets milled from a single block of aluminum, pinned together to save weight. They weigh it at 122g and compare it to a heavier, standard 11-34t steel cassette. They note they have used an identical gold version for about 1,000 miles, showing visible wear on the aluminum teeth but with shifting still perfect. They caution that durability is a trade-off, as the aluminum teeth will wear quickly if used frequently in hilly terrain. They mention the price has dropped since launch, and they purchased it for just over 60 pounds.
AI Summary
Pros
- Extremely lightweight (122g)
- Unique, weight-saving two-piece construction
- Shifting performance remains perfect even after 1,000 miles of use
more pros in the video
Cons

Elitewheels Velo Six II
Wheels
The reviewer tests and reviews the Elitewheels Velo Six II (Vevel 6 version two) wheel set. He states that the primary issue with the original version was poor lateral stiffness, which has been significantly improved in version two, making it nearly three times as stiff without added weight. The wheels are one-piece carbon, 50mm deep, with a 21mm internal width, weighing 1628g. They are designed for triathlon and road riding, offering high aerodynamic performance, a very stiff and responsive ride, and a distinctive, loud freehub sound. However, the ride is harsh on rough roads, and they are susceptible to crosswinds. The reviewer has ridden them for over six months and praises the bearing durability and anodized aluminum axle. They are not UCI-legal for road races.
AI Summary
Pros
- Looks great and is a head-turner
- Significantly improved lateral stiffness in version two (nearly 3x stiffer than original)
- No weight increase despite stiffness improvement
more pros in the video
Cons
- Lateral stiffness was a major issue in the original version
- Ride is harsh on rough roads due to zero vertical compliance
- Catches crosswinds due to large side profile, which can be unnerving
more cons in the video
Key Points
- Model: Elitewheels Velo Six II (Vevel 6 version two)

Winspace G3
Frame
The reviewer discusses the Winspace G3 gravel bike, comparing it to the G2 model. They find the G3 to be a nice road bike with responsive steering, despite a slack head tube angle. They note it is less comfortable than the G2 but prefer its handling and appearance. A major improvement is the traditional steer tube and larger bearings, which prevent headset loosening. However, they experienced a seat post issue due to a tapered clamp interface, resolved with carbon paste and proper torque. They recommend a two-bolt rail clamp for better security.
AI Summary
Pros
- Responsive steering, feels twitchy but good for road bike feel
- Traditional steer tube and larger bearings keep headset tight
- Improved headset stability over G2
more pros in the video
Cons
- Less comfortable/compliant than G2
- Seat post clamp interface is tapered and can slip under load
- Seat post shape proprietary, limiting adjustment options

LTWOO eRX Road Electronic Groupset, eRX 2x12s / 2x11s Electronic Groupset, ERX Replaceable Battery, APP Programming
Groupset
The reviewer purchased and installed the LTWOO ERX (referred to as L2, L2 V3, L2 ERX, and ERX) electronic groupset on a winter training bike, replacing Dura Ace Di2. They tested it for approximately 5 months. The reviewer states the rear shifting is fast, reliable, and crisp, comparable to other electronic groupsets. The front shifting is noted as noisy, clunky, and slow, reminiscent of older generation products. The app offers extensive customization, including selecting 11 or 12-speed operation and micro-adjusting individual sprockets, but the initial setup was challenging with a default Chinese language setting. The groupset uses a semi-wireless design with USB-C charging via the front mech, which is praised, and battery life is reported as good. The brakes require non-standard adapters for flat mount frames, which the reviewer dislikes. The groupset is significantly heavier than Dura Ace, comparable to Shimano 105. The price is a major advantage, coming in considerably cheaper than Shimano 105 Di2 when factoring in additional drivetrain components. The reviewer concludes it is a solid competitor to 105 Di2 for tinkerers and self-builders, but has compromises compared to top-tier groupsets.
AI Summary
Pros
- Rear shifting performance is fast, reliable, and crisp.
- Extensive app customization: can be set to 11 or 12-speed, micro-adjust individual sprockets.
- USB-C charging via the front mech is convenient and uses a universal charger.
more pros in the video
Cons
- Front shifting is noisy, clunky, and slow, not on par with Dura Ace.
- Brake calipers use a non-standard mount requiring ugly adapters for most flat mount frames.
- The groupset is heavy, comparable to Shimano 105 level, not lightweight.
more cons in the video
Key Points
- Model: LTWOO ERX (also called L2 V3, L2 ERX).
