evolve CIMA Speed Artist
FrameThe 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' and a Raw Carbon option planned for May/June 2026. 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 teased a gravel version, the Cima GR, which is aero-shaped, ultra-light (750g for M-size unpainted), and has clearance for 50mm tires, with a limited edition yellow/pink color shown at the Shanghai 2026 show. Bundle deals with wheels and components are available, and the ride is described as comfortable, stiff, and fast, with sharp handling. A riser bar is also in development for the GR. 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. 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.
AI Summary
Pros
- High build quality and attention to detail, with excellent packaging and a detailed manual.
- Comfortable ride quality, described as less harsh than some competitors like Winspace or Pardus, while still being stiff enough.

+9 more
Cons
- Significant toe overlap due to short front center geometry, especially concerning in larger sizes (e.g., ML, L, XL).
- Initial paint schemes included a widely disliked 'Nature chooses' slogan on the downtube, though 'no quote' options are now available.

SEKA Spear
FrameThe 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), 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. Quality control issues include misaligned components and seatpost wedge fit problems, but warranty support is available.

SEKA ExAero GR RDC
FrameThe 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.

Pros
- High-quality carbon construction and excellent build quality, with well-aligned BB and clean internal routing
- Aero design with integrated storage (downtube and top tube) and sleek aesthetics, appreciated for gravel racing
