Giant has launched a brand new Trinity Advanced SL time trial/triathlon frameset, in addition to the parallel Liv Avow Advanced SL ladies’s model. It claims that the brand new frames supply decrease weight, improved aerodynamics and extra management, in addition to better adjustability.
The earlier technology 2016 Trinity/Avow was wanting decidedly old fashioned, and Giant has swapped to disc brakes from rim brakes and re-designed the frameset, cockpit and hydration/feed options for the brand new bike. Tyre clearance is now 30mm.
We first noticed the brand new Trinity below Luke Plapp as way back as April 2024, however the bike is barely now being launched.
Giant claims a 558g weight saving for the Trinity and 433g for the Avow, with a 4.36kg frameset weight, and a 5.9 watt enchancment in aerodynamics over the earlier mannequin at 45km/h for the tri configuration.
At the identical time, it’s up to date its Cadex disc and 4-spoke wheelsets.
There are two frameset choices for the Trinity, the Trinity Advanced SL for triathlons and the Trinity Advanced SL TT for time trials. Liv has to this point solely introduced the tri configuration though it is displaying the TT bike utilized by the Liv AlUla Jayco ladies’s WorldTour staff.
The tri model has an built-in hydration system with 850ml capability for the Trinity (700ml for a dimension S Trinity and for all however the M dimension Avow) that sits low within the body and a bento field with elevated capability that may maintain as much as six gels. The TT frameset has an exterior aero-optimised downtube water bottle and cage.

Giant has switched to its increased spec Advanced SL grade composite carbon fibre from the earlier technology frameset’s Advanced grade carbon, which it says accounts for the 558g/433g weight reduction, alongside a corresponding improve in stiffness-to-weight and, it says, a way more dynamic trip high quality.
At the identical time, Giant claims a smoother trip because of a rise in compliance of 28 p.c on the armrests and one hundred pc on the seatpost.
Both tri and TT framesets profit from a brand new fork, which helps to protect the disc brake calliper. The body tube profiles have been up to date too, including to the aero effectivity.
Greater adjustability
Giant has additionally elevated the match adjustment on supply.
There are 4 seatpost offsets obtainable, as an alternative of the earlier body’s two. The armrests may be adjusted by way of 80mm in stack and 75mm in attain, up from 60mm for each. There at the moment are eight armrest width settings as an alternative of six and 4 width settings for the extensions, up from two. The armrests may be adjusted to 3 totally different angles.
Giant says that its spacer system makes adjustment less complicated and the 2 bolt fixing mechanism makes it simpler to dismantle for transport.
The Giant Trinity SL frameset is out there in 4 sizes, XS to L, and the Liv Avow in 4 sizes from XXS to M.
The Trinity tri frameset is priced at £3,749 / $4,400 / €4,400 / AU$6,999. The Trinity TT frameset is $100 / €100 cheaper, though the identical value because the tri frameset within the UK and Australia.
There are additionally as much as three full bike specs for the Trinity tri obtainable in sure markets, though the Avow seems to be bought frameset-only in tri configuration at current, priced at £3,749 / $TBA / €4,199 / AU$ TBA.
New Cadex 4-spoke and disc TT wheels
At the identical time, Giant’s Cadex efficiency element model has launched a brand new aero wheel-tyre system for triathlons/time trails, with 4-spoke entrance and rear wheels and disc rear wheel.
The Cadex Aero WheelSystems have a 22.4mm inside width hookless design. Cadex says that the design reduces rolling resistance, will increase sidewall assist and improves cornering grip.
The Max Aero Disc WheelSystem disc wheel has a claimed weight of 1000g. Under the 1k carbon weave outer, there are carbon spokes which may be independently tensioned.
Cadex claims that, in addition to being 150g lighter than its predecessor, the brand new disc wheel has over 50 p.c better lateral stiffness and over 20 p.c better transmission stiffness.
The wheels spin on Cadex hubs with ceramic bearings, with a claimed 30 p.c discount in friction.
The Aero 4-Spoke wheels share the 22.4mm width hookless rim of the disc rear wheel and roll on a low friction aero hub, additionally with ceramic bearings.
The entrance wheel has a 50mm deep profile, whereas the rear wheel is 65mm deep. Cadex claims higher aero efficiency and stiffness-to-weight than the Roval 51/321 and Zipp 858 wheelsets, primarily based on its testing.
The new 4-Spoke wheels are claimed to be 6.4 watts quicker at 45km/h within the new Trinity/Avow frameset than the Cadex 65 WheelSystem within the earlier technology body.
Claimed weights are 880g for the entrance and 1,047g for the rear 4-spoke wheels.
Cadex affords a lifetime guarantee and 5 yr incident alternative on all three wheels. It hasn’t supplied costs.
