We liked the primary iteration of the Ventum GS1, a lot in order that it acquired our Editors Selection award for 2020. It was not with out its shortcomings, although, and the world of gravel and gravel racing has modified quickly up to now three years. What appeared like an ample quantity of tire clearance then is now equal to a cyclocross bike. The identical is alleged for developments in gravel geometry. Plainly Ventum was listening, gathering concepts, and prototyping.
After a lot suggestions from their gravel racing athletes and the driving world at massive, Ventum shortly up to date its flagship gravel machine. In pursuit of making a quick gravel race bike, Ventum opted for bigger tire clearance, an extended wheelbase, and tweaked the geometry for higher dealing with off the pavement.

The earlier mannequin shared extra traits of a cyclocross bike, whereas the brand new model appears like an aero-gravel design. Essentially the most notable being the swooped seat stays, a beefed up entrance finish, and an extended wheelbase.
Ventum GS1 2023 Body Particulars
For this iteration of the GS1, Ventum pivoted from excessive gloss paint to matte however caught with the earth (gravel) tones. The matte paint hides scratches and mud higher than the gloss end in my choice however lacks a few of the pop of the earlier providing.
The brand new GS1 is obtainable in 4 colorways; Sage, Moss, MOAB, and Storm.
Extra Room for Enjoyable
The GS1 now clears as much as 700c x 48mm and 650b x 2.1″ with some room to spare. The geometry is tweaked barely with a further 10mm of attain and wheelbase. The up to date entrance finish neatly shops cable in a barely completely different headtube design recessed into the body.

Preliminary impressions
Ventum is direct to client, and the bikes arrive to the purchaser in tip-top form for meeting. I used to be greatly surprised by my final overview of the care taken within the pre-build course of, and this time was no completely different. I’ve seen all method of pre-built bikes, and more often than not, you need to test each single bolt with a torque wrench or rebuild fully.
The Ventum GS1 arrived totally dialed, shifters paired, and brakes mattress in. The one factor I wanted to do was set up the stem and dial within the match. I nonetheless checked it over with a torque wrench, however the construct high quality and a focus to element are very good.
The longer attain meant working a shorter-than-usual stem to get my match proper. The bike arrived with an 80mm stem, which turned out proper on the cash. Coming from the earlier mannequin, the brand new GS1 has an aggressive really feel. After doing the headset spacer dance, I landed on a snug match. The Enve Gravel bars are wider than the 42cm conventional bars I trip which means the setup and flare can take a bit to get used to, particularly for these coming from a extra conventional setup.
The up to date GS1 headset and cable administration system took a while to good, however I discover this a headache on most bikes. It sits very flat on the body and offers an excellent clear look, and it’s a pleasant replace. Notably, you may change the stem and spacer place with out having to mess with the cables. Although like many trendy bikes with inside routing by means of the headset, altering the headset bearings is much extra difficult.
Journey impressions
The GS1 arrived simply as we have been experiencing a winter warmth wave in Pittsburgh. The as soon as frozen strong gravel roads turned to power-zapping slogs. I took the Ventum GS1 out for its inaugural rides on these roads, not solely testing my winter form however the energy switch within the up to date gravel race machine.
On the pavement, the GS1 rides like an aggressive street bike with all of the response you’d count on from a performance-focused body. The steering is a departure from the street really feel, rolling down sweeping descents and tight roads. The GS1 is extra of a gradual and regular driver. I used to be nonetheless getting used to the trip, however it was clear this bike excels extra chugging on the flats and fewer slicing/dicing on the turns.
Once I lastly hit the gravel, the GS1 got here into its personal. The chatter I anticipated on the blown-out gravel roads was extra of a hum. Whereas descending, the GS1 feels planted, even on gentle, unfastened gravel. The lengthy and low feeling soaks up small bumps, and the regular steering is an asset on sketchy gravel descents.
The place the GS1 outperforms different bikes is on flat or rolling gravel. The up to date geometry put the rider in a barely extra aggressive place, however not out of the consolation zone. The place seems like a mixture of a street and cyclocross match, extra focused on energy manufacturing, and the bike plows ahead.
Most of my overview rides have been a mixture of gravel, street, and a few single monitor. The GS1 does nicely on all terrains however is most at house on gravel. The bike shortly responds to energy on the pedals, and the reconfigured rear triangle soaks up bumps and not using a lack of feeling.
The broader tire clearance is a welcome replace, however I felt snug on the 38mm tires of the earlier model. My native gravel isn’t very loopy, however I felt the body of the GS1 did many of the heavy lifting for smoothing out the trip.
Last ideas
The extra I amassed miles on the up to date Ventum GS1, the extra I preferred it. The body is responsive and might maintain its personal on the flats and climbs. The burden alone will entice some gravel weight-weenies. However its most excellent function could be the snug trip the GS1 provides at a race tempo.
Rolling onerous on gravel, I wasn’t holding the bars for pricey life; I used to be in management, driving the bike and searching forward. We take these items with no consideration on a trip, however when race day comes, all of the fatigue that comes from being jackhammered by gravel roads takes a chew out of your total efficiency.
If something, the GS1 is greatest described as a devoted gravel race bike. It performs nicely on the street and trails, however gravel is the place it’s house.
