- Lightweight for an aero frame (sub-1000g)
- High-quality build, fit, and finish with clean cable routing
- Excellent tire clearance (up to 38mm measured)
Cons
- Steep seat tube angle (74°) may cause fit issues for riders needing significant setback
- Limited seatpost setback (8mm stock; 15-20mm not yet available)
- Crosswind stability marginally worse than some competitors
- Fork design has an upward-angled ridge that may affect aerodynamics
Key Facts
- Price: $1650-$1900 USD for frame, fork, seatpost, handlebar, and custom paint
- Weight: 930-994g (size M, unpainted); 961.9g (size L painted without hanger)
- Tire clearance: 35mm official, fits up to 38mm measured tires
Reviews & Ratings
The reviewer discusses the XMCS VRT frame and wheels, noting that the wheels have a problematic spoke lacing pattern (radial lacing on the rear disc side) which is known to put more pressure on spokes, leading to a spoke breaking within a month. The reviewer lost confidence in the wheels and cannot recommend them, suggesting they should be avoided. The frame is described as having a slender head tube, T47 bottom bracket, UDH, and tire clearance up to 34mm measured (likely fitting 38mm measured tires). The frame is priced around $1,700 USD for frame, fork, and seatpost, or $1,900 with handlebars and custom paint option.
AI Summary
Pros
- Frame has T47 bottom bracket
- UDH compatible
- Can fit up to 38mm measured tires
- Custom paint option available
- Uses FSA ACI headset system for wide stem/handlebar options
Cons
- Wheels have radial lacing pattern on rear disc side, which is weaker
- Spoke broke within a month of use
- Reviewer lost confidence in wheels and recommends avoiding them
- Wheels cannot be relaced due to spoke hole drilling
- Frame's head tube design may affect aesthetics (bearings sit above top tube)
Key Points
- Frame and wheels are from XMCS, a brand known for value high-quality wheels
- Frame originally intended to be called 'Aries' but trademark issues led to 'VRT'
- Frame price: ~$1,700 USD for frame, fork, seatpost; ~$1,900 with handlebars and custom paint
- Tire clearance: claims 34mm measured, but can fit 38mm measured with 1x setup
- Wheels use Sapim spokes (reviewer unsure if spoke or lacing pattern is the issue)
- XMCS moving to different spokes (Alpena) for future wheels
The reviewer discusses the XMCS AERYS:VRT (unreleased), now renamed XM Carbon Speed VRT or XMS VRT, a frame set from XM Carbon Speed. They highlight its price ($1,900-$2,000 USD), wind tunnel results showing it outperforms the QuickPro ER1 and is comparable to the Cervelo S5, especially with rider-inclusive testing where it achieved the lowest drag. The reviewer notes excellent build quality, fit and finish, and recommends the frame after 1,000 miles, but cautions about geometry fit due to a steep seat tube angle (74°) and limited seatpost setback.
AI Summary
Pros
- Competitive price ($1,900-$2,000 USD) for frame, cockpit, and custom paint
- Wind tunnel results show lower aerodynamic drag than QuickPro ER1 in all configurations
- Comparable aerodynamic performance to Cervelo S5 in bike-only testing
- Achieved lowest rider-inclusive drag among tested bikes (VRT with Carbon Speed wheels)
- High-quality fit, finish, and paint; easy to build with clean threads and cable routing
- Accepts up to 35C tires (measured at rim), with clearance for 38C on 1x setups
- Feels fastest in a straight line, especially in tailwinds; responsive and nimble
- Excellent value for aerodynamic performance
Cons
- Seat tube angle (74°) may not suit riders preferring traditional saddle setback; reviewer struggled to achieve ideal fit
- Seatpost has only ~8mm setback, though a 15-20mm setback post is planned
- Crosswind stability marginally worse than QuickPro ER1 and Scott Foil RC Pro
- Brand cache and racing pedigree less established compared to QuickPro ER1
- Geometry requires careful verification to ensure proper fit
Key Points
- Frame set, cockpit, and custom paint cost $1,900-$2,000 USD
- Renamed from XMCS AERYS:VRT to XM Carbon Speed VRT or XMS VRT due to paperwork issues
- Wind tunnel testing at Silverstone at ~45 km/h; aerodynamic drag accounts for ~85% of resistance
- VRT with Carbon Speed wheels achieved lowest Cda (0.0742) among tested combos
- Rider-inclusive testing: VRT with Carbon Speed wheels had Cda of 0.3313, fastest overall
- Frame tested with 32C Continental GP5000 tires (measured 34.5mm at rim on 26mm internal width wheels)
- Seat tube angle: 74°; seatpost setback: ~8mm (15-20mm version forthcoming)
- Frame size 56 weighed 7.4 kg all-in (including pedals, cages, computer mount, power meter)
- Recommended for riders comfortable with forward saddle position
The XMCS AERYS:VRT is a new aero road frame from XMCS, initially priced at $1650 USD (frame + hardware) but updated to $1800-$1900 including handlebar and basic custom paint. It weighs approximately 930-994g (size M, unpainted) with a painted size L frame at 961.9g (without derailleur mount/UDH hanger); fork uncut 470g, cut 439g; seatpost uncut 192.1g, cut 167.1g. The frame offers 35mm tire clearance (can fit up to 38mm measured tires), is made from carbon fiber using a monobloc mold, and features a 2-bolt saddle clamp, zero and 15mm offset seatposts (20mm setback expected soon), and compatibility with mechanical and electronic shifting. It is designed for aerodynamics with a deep headtube, narrow front profile, and completed wind tunnel testing at Silverstone. Results show the VRT is aerodynamically competitive with the Cervelo S5 and Quick Pro ER:One; with rider, it was slightly faster than the S5 in some configurations. The frame is available in sizes M, L, and XL (XS not yet), with full size range expected Summer 2026. Early reviews highlight excellent straight-line speed, responsive climbing, and comfort slightly better than the Scott Foil and Quick Pro ER:One, but note crosswind sensitivity and fit challenges for riders needing significant saddle setback due to the 74° seat tube angle. The fork design has been critiqued for its upward-angled ridge, but overall quality and engineering are praised, with positive feedback from aero engineers at Eurobike. A full review video has been published by patliean1, but the complete wind tunnel PDF report has not yet been made public. The Eurobike demo bike weighed 6.48kg (excl pedals).
