Trek Domane 4 Series blows past any other carbon endurance race bike in its class, with IsoSpeed for comfort, endurance geometry for stability, and Power Transfer Construction for speed.
Ride and Handling Trek Domane:
Any worries that a lower grade of carbon or verbal description would dilute the effectiveness and performance of the four.3 ar unwarranted – it’s one.8kg (4lb) heavier however conjointly £5,200/US$4,430 but the vi.9, and for £1,800/US$2,499 you get a merely astonishing frame associated an habit-forming ride quality. 
First ride impressions ar fairly typical, till you realise that the same old road chatter and vibration is muted to the purpose of being barely noticeable, though the road feel, thus crucial to specific handling, is unaffected.
Arguably, the road feel was accentuated as a result of the Domane appears to be in touch with the surface a lot of of the time. Turning into corners on roughly patched tarmac was refreshfully unspectacular, the wheels ostensible to finish and bite rather than skipping across the surface.
With such spectacular stability and poise, exploring the Domane’s limits becomes obligatory on virtually each ride. have a look for rough stuff expecting to lose fillings and instead you’re cosseted by a utterly light feeling.
Of course, on the foremost extreme roads there’s still a component of vertical movement, however sudden kicks and general vibration ar removed. Not beating regarding the bush – the Domane’s ride is no wanting astonishing.
Frame and Equipment Trek Domane:
The IsoSpeed system doesn’t have a threshold below that it feels inert. there’s no intrusive movement that might have an effect on your pedalling action, because the active part of the Domane is that the whole seat tube, not simply the seatpost.
The decoupler is essentially a move pivot attaching a lug on the front of the seat tube to the highest tube, permitting the tube to bow and flex on its length in isolation from the frame, with no a lot of result on seating position than a slim carbon seatpost. The magnified active length leads to many times a lot of shock absorption while not the requirement for excessive movement in a very restricted house.
Complementing the seat is that the IsoSpeed fork. This includes a one one/8in to 1 1/2in tapered steerer tube for immense rigidity, and a relentless radius curve that continues slightly sooner than the dropout to maximise its bump-smoothing ability.
Despite sounding sort of a full suspension bike, the Domane sports associate outsized down tube and muscular uneven chainstays, that wrap a merely huge BB90 bottom bracket shell, and combined with the fork’s lateral stiffness build it as responsive as any quick road bike out there.
As ever, at this worth there ar some components we’d quickly upgrade, and with such a lot technology within the Domane’s frame the wheels ar the plain place to start out. The Bontrager Approved hoops roll we have a tendency toll and resisted the worst we might fling them at with no issues, however they arn’t on constant level because the frame and are a bit sluggish.
Shimano’s one hundred and five was immaculate as ever, although Trek still embrace associate integrated chain catcher to forestall it dropping between chainset and bottom bracket. The completely Bontrager finishing kit is all competent stuff, however may gain advantage from even handed upgrading once budget permits.
That said, we’d lief {choose to|prefer to|like better to|value a lot of highly to|favor to|opt to} take the Domane out a lot of typically than more exotic machinery as a result of the frame offers such a lot comfort with no performance penalty. A spectacularly straightforward however fantastically accomplished style.
