Overview

One of the closest practical matches for an aero, relatively light, very-wide-clearance build, but it remains a purpose-built race-gravel chassis rather than a road-geometry frame.

Best for: premium aero racer

TEST - Seka ExAero GR: The Chinese gravel racing bike that's driving everyone crazy

Italian-language hands-on test covering the ExAero GR platform on varied terrain; treat ride impressions separately from official specifications.

BiciDaStrada · 2026-03-12. This is a professional publication test; the product-supply and commercial terms were not independently verified. Disclosure basis.

Takeaways

  • Repeats a maker claim0:27Repeats SEKA's claims: one-piece monocoque frame of Toray T1100G and M46J at 980 g raw in size 54, a seatstay 'wind eye' that lets the rear flex about 16 mm, 423 mm chainstays, and 56 mm front / 52 mm rear tire clearance (Italian, automatic captions).
  • Build note3:15FIDLOCK-latched down-tube storage with a supplied bag that opens one-handed, rubber chainstay and down-tube guards, threaded T47, and a mount for 2× as well as 1×.
  • Price at publication5:26Sold only as a frame kit (frame, fork, Gladius GR integrated cockpit and seatpost, 15 bar/stem combinations, straight or 15 mm setback post) at €3,099 in March 2026.
  • Measured5:34The top-spec size-54 test build weighed 7.9 kg without pedals and just over 8 kg with them.
  • Ride impression6:08At 172 cm the tester found the 54 compact and racy; it climbs like a road bike and is fastest on flat gravel, but is stiff and demanding on rough descents, so he recommends lower-profile wheels and careful tire pressure for rough terrain.

SEKA ExAero GR Unboxing: My 2027 Gravel Race Bike

Unboxing and weigh-in of a size-58 SEKA ExAero GR frameset bought for a 2027 gravel race season.

Dwayne Pedals · 2026-10-16. US SEKA dealer Power Meter City sent the frameset, and the presenter promotes the dealer in the video. Disclosure basis.

Takeaways

  • Support0:10The presenter waited about six months; in the US the frame was stocked by a single dealer at the time (October 2026).
  • Build note8:00Needs an outboard-bearing T47 bottom bracket; the box includes down-tube storage bag, bottom-bracket, down-tube and chainstay protectors, UDH hanger, a front-derailleur mount option and a titanium top-cap bolt.
  • Fit check12:16SEKA's figures cited here: 56 mm front and 52 mm rear; fitting a front derailleur may reduce usable tire size.
  • Measured14:14The size-58 frame weighed 1.22 kg as unboxed, the zero-offset seatpost 185.5 g and the Gladius GR bar (110 mm stem, 38 cm) 425 g.

SEKA ExAero GR Gravel Bike - Everything You Need to Know

US dealer's buyer guide to the SEKA ExAero GR after a year of racing: tire-fit caveats, standards, cockpit and price.

Power Meter City · 2026-09-08. Published by Power Meter City, a US SEKA dealer; the presenter has raced the frame for about a year. Disclosure basis.Watch on YouTube

Takeaways

  • Repeats a maker claim2:06SEKA's 980 g claim for a size 54 is unpainted; the dealer expects about 1,100–1,200 g painted. The seatstay 'wind eye' is claimed to flex up to 16 mm.
  • Build note4:39It needs an outboard T47 bottom bracket (inboard versions do not fit), UDH, 12×100/12×142 axles, and zero-offset or setback seatposts; the thru-axle hex holes were tight and grabby on his frame.
  • Fit check5:37SEKA rates 56 mm front and 52 mm rear, but the dealer knows riders who could not fit that: on 32 mm-internal rims a 50 mm tire can spread to about 52–53 mm and fail to fit the rear, so check rim width and tire together.
  • Price at publication8:48In September 2026 the frameset (frame, fork, seatpost) retailed at US$2,799, or US$3,299 with the Gladius bar, which he found stiffer than SEKA's road bar.

I am SHOCKED by this SEKA Gravel Bike! *SEKA ExAERO GR*

Size-56 SEKA ExAero GR built with SRAM Force XPLR and 29×2.2 in mountain-bike tires, with a weigh-in and clearance walkaround.

GC Performance · 2026-07-03. Build walkaround by a US shop-owner YouTuber; how the frameset was obtained is not stated. Disclosure basis.Watch on YouTube

Takeaways

  • Measured0:15The size-56 build with SRAM Force XPLR, Drive G42 wheels, 29×2.2 in tires, pedals, power meter, cages and mount weighed 8.61 kg.
  • Fit check3:28His 48T ring left enough room that he thinks a 52T would fit with spacing; a front-derailleur mount allows 2×. 29×2.2 in tires (about 55 mm by his estimate) fitted front and rear with room at the stays, above SEKA's 52 mm rear rating.
  • Ride impression5:20He found the reach comfortable at 25 mm of spacers with a 120 mm stem, and the long, shallow Gladius drops a comfortable alternative position on straight roads.
  • Finish and faults11:40No paint on any mounting surface, a cleanly chased outboard T47 shell and brake mounts that aligned easily; titanium hardware throughout and a proprietary alloy out-front mount.

NEW SEKA Exaero GR Build With the Chainbox Pro Mechanic

UK shop build of a SEKA ExAero GR after a faulty first frame was replaced, with the mechanic's assessment of finish, routing and clearance.

Ben_skillz · 2026-02-20. UK rider's build video with his mechanic; how the frameset was obtained and any sponsorship are not stated. Disclosure basis.Watch on YouTube

Takeaways

  • Finish and faults2:41The first frame had an unspecified fault, so the mechanic declined to build it; SEKA shipped a replacement from China in just under a week.
  • Build note9:05The mechanic found the build smooth apart from routing hoses through the one-piece bar; he praised the channelled fork routing, flat-faced brake mounts, T47 threads that ran in by hand and a clean frame interior.
  • Build note11:34Split clip-off headset spacers let the stem height change without disconnecting the hoses; the long seatpost must be cut because insertion is limited.
  • Fit check16:37A 50 mm rear tire on Zipp 303 XPLR S wheels was close but cleared; the front Thunder Burt had plenty of room.
  • Fit check17:15With this crankset the chainring sat only about 2 mm from the chainstay; the mechanic put that down to the chosen crank offset, not the frame.

    Official brand source for the premium aero gravel platform.

  2. SEKA ExAero GR

    SEKA · Manufacturer product pageProduct facts: High · accessed 2026-08-28

    Official exact-model page supports 56 mm front and 52 mm rear clearance, a 980 ±35 g unpainted size-54 frame claim excluding paint and hardware, Toray T1100G/M46J carbon, true one-piece molding without joined or bonded frame sections, 106 N/mm rear vertical compliance, up to 16 mm seatpost movement, T47 68 mm and the full 49–61 geometry table. The page links an official Taobao route but did not expose a current CNY checkout in this pass.

  3. SEKA warranty policy

    SEKA · Manufacturer warranty pageProduct facts: Medium · accessed 2026-08-27

    Official policy states lifetime coverage for the frameset category, five years for carbon-fiber components and two years for spare parts, subject to the policy's eligibility and exclusions.

  4. Compiled China carbon gravel market research

    China Bikes · Research noteProduct facts: Medium · Price: Medium · accessed 2026-08-06Archived evidence; no public link

    Cross-checked compilation of public product pages, marketplace references, Chinese industry sources, and dated price observations. Approximate values require fresh verification.

  5. SEKA road ExAero identity boundary — not ExAero GR

    SEKA自行车 public account · Manufacturer community postProduct facts: Medium–high · accessed 2026-08-27

    Exact road-model post reports an 820 g frame, T1100/M46J carbon, one-piece molding, seven race-oriented sizes and Gladius or ALTA cockpit options. The current official product page independently matches these specifications. When referenced by an ExAero GR record, this is rejection/disambiguation evidence only and supports no GR specification.

  6. SEKA official online store

    SEKA Bikes · Official storefrontProduct facts: Medium · accessed 2026-09-01

    Current official online store lists the exact ExAero GR frameset at US$3,299 with Shop Now. Storefront scope is US and Canada; prices include applicable import duties, taxes and tariffs and orders over US$299 ship free. It does not establish mainland China checkout terms.

  7. SEKA ExAero GR store route recheck

    SEKA · Manufacturer storefront recheckProduct facts: Unverified · accessed 2026-09-25

    The current homepage lists standard ExAero GR at US$3,299, but its Shop Now path leads to the distinct ExAero GR RDC frameset page, which showed sold out. RDC availability does not establish an active purchase route for standard ExAero GR. Mainland China terms were not verified.

  8. Seka ExAero GR review

    Cycling Weekly · Independent editorial reviewProduct facts: Medium–high · accessed 2026-08-28

    Exact-model large-frame test reproduces SEKA's vertical-compliance and lateral-stiffness figures, then reports normal behavior at 200–270 W but enough rear lateral flex above about 360 W to disrupt shifting across four wheelsets. This is rider/build-specific qualitative evidence, not a universal threshold.

  9. SEKA ExAero GR current manufacturer page recheck

    SEKA · Manufacturer product page recheckProduct facts: High · accessed 2026-09-23

    The current exact gravel model page reconfirms an unpainted size-54 frame weight of 980 +/- 35 g excluding paint and hardware, six sizes, 423 mm chainstays and size-dependent 70-74 mm BB drop. The linked geometry chart is image-only; the retained manufacturer chart extraction remains the basis for the full geometry table.

  10. SEKA ExAero GR

    SEKA · Manufacturer product page recheckProduct facts: High · accessed 2026-09-24

    Current exact GR page specifies Toray M46J and T1100 carbon and one-piece monocoque construction. No ply schedule is published; this is distinct from road ExAero.

  11. SEKA ExAero GR current stiffness and compliance statement recheck

    SEKA · Manufacturer product page recheckProduct facts: High · accessed 2026-09-25

    The manufacturer page states up to 16 mm seatpost movement and 106 N/mm rear vertical compliance, claiming this improves vibration damping without compromising power transfer or lateral stiffness. This vertical-compliance figure is a different axis and test basis from Cycling Weekly's single large-frame lateral-flex observation; no universal stiffness score or threshold is supplied.
