The ONIRII One Frameset is a lightweight carbon road bike frameset designed as an affordable alternative to the Specialized Aethos. It features a T800 carbon fiber construction with BSA bottom bracket, 27.2mm seatpost, and disc brakes. The frameset has undergone updates including a fully internal cable routing (ICR) version. Key attributes include a retail price around $840 with shipping, frame weights ranging from 685g to 845g depending on size and layup, and a 30mm listed tire clearance (though users report 32mm tires can fit). The frameset has an 85kg weight limit that concerns some users. It's available through Onirii's AliExpress store and various open mold sellers, with the open mold version being cheaper but lacking some components.

The Evolve CIMA Frameset is a lightweight carbon road bike frame, with users noting a claimed weight of around 650-777g for the frame. It is priced around 3,000 EUR, positioning it as a premium option, though some users consider it expensive compared to alternatives like the Cannondale Supersix Evo Hi-Mod. The frame is made from carbon fiber, with a seatpost battery holder for Di2 systems, and features a UDH hanger. It is produced by the same company behind Elite Wheels, and is available through various retailers including Mantel and PandaPodium, as well as directly from Evolve with taxes included. The geometry is similar to the Specialized Tarmac SL8, with a short front center and low fork offset, leading to agile handling but potential toe overlap, especially in larger sizes. Initially, frames came with a 'Nature chooses' slogan on the downtube, which was widely criticized; the company now offers 'no quote' paint schemes without the slogan and, later, without the trademark symbol (®) on some colorways, though the Rewind color cannot be ordered without the ®. New colors include 'Navy white', a Raw Carbon option (which is actually a matte black paint) released in May/June 2026, and the Billow white with a deep glossy pearl-like finish. Build quality, packaging, and the included manual are frequently praised as excellent, and customer service has been noted as responsive. The integrated Kreuza handlebar is stiff and performs well, though some users criticize its shape for creating a trough before the hoods. Tire clearance is generous: users have fitted 35mm tires (measuring 35.9mm) with only 2mm clearance on chainstays, making it uncomfortably tight for wet conditions; 32mm tires are recommended. Evolve has launched a new website at evolvebicycles.com and released the Cima GR gravel version, available in Sailfish Pearl and Sahara Nude colors, with 50mm tire clearance, a medium frame weight of 820g painted, and a price $300 lower than the regular Cima (without CeramicSpeed SLT bearings). The GR also introduces the Kreuza Apex riser bar. Bundle deals with wheels and components are available, including a 'CIMA Bundle 2026 Summer Sale' for $3698 that includes the frameset, Kreuza Apex handlebar, Elitewheels Drive SL 48D CS wheelset, and an Evolve X Cycling Kit. The ride is described as comfortable, stiff, and fast, with sharp handling; a recent direct comparison by an SL-8 owner found the Cima soaks up bumps better and has slightly less nervous steering, leading him to say he would choose the Cima over the SL-8 if buying today. Notably, Evolve lost a trademark dispute in the EU, leading to deletion of its EU trademark and potential legal issues for EU importers; the website was briefly down for EU visitors but is now accessible again, though intermittent issues persist. Individual customers ordering from China face low risk of seizure. A size Small Cima build with Dura-Ace and Farsport wheels achieved 6.23 kg. For sizing, a rider 181cm with a short torso is recommended to choose Medium over M/L, as the Medium has identical geometry to a Tarmac SL8 size 54. Recent reports indicate stock availability issues, with one customer told after ordering that there was little or no stock and to expect 30-40 days for production plus shipping, potentially totaling up to 60 days; another received wheels in 23 days and frameset in 36 days earlier in the year. Customer service remains responsive, and a user asked about maximum saddle rail incline angle, with Evolve and Panda Podium suggesting rails should be level or slightly down.

The XDS X-LAB AD9 (also referred to as RT9) is a lightweight carbon road bike discussed by forum users. It's compared to the Specialized Aethos, with users noting its competitive weight (around 6.1kg in a ready-to-ride setup with 50mm aero wheels) and potential as a more affordable alternative. Key attributes mentioned include its use of high-modulus carbon fiber to achieve low weight, IS52 headset standard for compatibility, and mixed signals about international availability. Users debate whether it's a direct Aethos competitor or knockoff, with some noting limited production and high costs.

The Seka Spear is a lightweight, aero-optimized road frameset from a Chinese brand, gaining popularity for its performance and value. It features a carbon fiber construction with a unique 'Wind Eye' seatstay design for claimed vibration damping and aerodynamics. The frameset includes an integrated Rapier cockpit and is available in standard and RDC (Race Design Carbon) versions, with the latter using higher-modulus carbon for reduced weight. Key attributes noted by users include competitive weights (e.g., ~800g for a medium frame in Chronos color, ~815g for Large Shadow Black, ~910g for XL Cronos), BSA threaded bottom bracket, and a max tire clearance of 32mm (though some users fit up to 35mm tires on specific rims, with tight clearance). Pricing is generally lower than Western brands like Specialized SL8, but availability can be limited with long lead times. Ride impressions highlight a stiff, responsive feel good for climbing and descending, with comfort praised by many, especially in the rear, though some report a harsh front end, disc brake rub, or road buzz. Users have achieved very low build weights, with complete bikes around 6.2kg and extreme RDC builds as low as 4.96kg. Quality control issues include misaligned components, seatpost wedge fit problems, and handlebar wobble in crosswinds, but warranty support is available. The frameset supports various computer mounts, though compatibility may require adapters for devices like Hammerhead Karoo. A new TT frame with Wind Eye design has been released. Sizing advice varies: some users size down with spacers for agility, while others match geometry to existing bikes.

The Seka ExAero GR RDC Frameset is a high-end, race-oriented gravel bike frameset introduced in 2025. It features an aero carbon design with integrated storage in the downtube and top tube, similar to the Tideace Noah. The frame is offered only in an RDC (Race Day Carbon) version, with a price around €2,999 (or $4,200 CAD including cockpit). It has a claimed tire clearance of 52mm rear and 56mm front, though real-world reports suggest it may be tighter, especially with wider rims. The geometry is described as short and upright, with a high stack-to-reach ratio and a relatively high BB drop (e.g., 72mm for size 54), making it suitable for aggressive gravel racing but potentially less stable for technical terrain. The frame weight is around 900g unpainted (size M), with a complete frameset (frame, fork, seatpost, handlebar) weighing approximately 2,200g. Build quality is praised, but some details like the plastic storage cover and upward-angled computer mount are criticized. Availability has been limited, with delays reported.
