A November 2025 review of a fourth-generation Domane SL 6 with 105 Di2 and Bontrager carbon wheels on the same Gen 4 SL frame as the SL 5 recorded here, with a weigh-in, clearance, storage and ride impressions. The recorded SL 5 uses mechanical Shimano 105, so its weight and wheels can differ.

Takeaways
Price at publication0:36The SL 6 with Shimano 105 Di2 cost £3,900 at publication, with the range starting at £2,800; he noted a Giant Defy with the same groupset and similar carbon wheels was £600 less.
Fit check3:53He gives 38 mm tire clearance without mudguards and 35 mm with them; the bike came on 32 mm tires, and he expected a 40 mm tire to be tight.
Build note4:42Semi-internal routing keeps a round alloy bar and stem that are easy to swap; there is in-frame storage with a large lever, plus mudguard, top-tube bento and extra down-tube mounts.
Measured6:24His size 56 with 105 Di2 weighed 8.9 kg on his scales, heavier than he expected; he put its Bontrager carbon wheels at nearly 1,700 g, with a narrow 19.5 mm internal width.
Ride impression7:42The IsoSpeed decoupler made the saddle very smooth on rough roads, though it is no longer adjustable, so flex depends on rider weight; the front end felt firmer, a bike of two halves.
Ride impression10:26It lacked urgency: on fast club rides he felt he worked harder to keep up than on a sportier Giant Defy, so he sees it as a bike for maximum comfort and a relaxed fit.

An owner's six-month, 1,500 km review of a Trek Domane SL 5 Gen 4 bought as his first road bike.

Takeaways
Ride impression0:42Very comfortable: he rides 100 km without back pain, helped by the rear IsoSpeed decoupler; comfortable enough that he slammed the stem.
Build note1:21The stock tires were poor; switching to 28 mm Pirelli P Zero Race TLR was the best-value upgrade, followed by carbon wheels.
Build note2:01In-frame storage is the feature he values most; internal routing does not bother him because a mechanic services the bike.
Price at publication3:53He paid about US$3,500 for the 105 mechanical SL 5; the SL 6 adds 105 Di2 and better wheels for about US$1,200 more.
Finish and faults5:50Cons: 105 at this price, on the heavy side because of IsoSpeed and storage, bar tape wearing quickly, a top-frame plug that fell out, and a seatpost that slipped down even when tightened fully.
