Preliminary impressions
Ventum is direct to client, and the bikes arrive to the purchaser in tip-top form for meeting. I used to be shocked by my final evaluate of the care taken within the pre-build course of, and this time was no totally different. I’ve seen all method of pre-built bikes, and more often than not, you wish to examine 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 operating 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 journey 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 provides a brilliant 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 via the headset, altering the headset bearings is way extra difficult.
Trip impressions
The GS1 arrived simply as we had 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 journey, nevertheless it was clear this bike excels extra chugging on the flats and fewer slicing/dicing on the turns.
After 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, free 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 looks like a mixture of a street and cyclocross match, extra focused on energy manufacturing, and the bike plows ahead.
Most of my evaluate rides had been a mixture of gravel, street, and a few single observe. The GS1 does effectively on all terrains however is most at residence on gravel. The bike rapidly 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 journey.
Last ideas
The extra I gathered miles on the up to date Ventum GS1, the extra I preferred it. The body is responsive and may maintain its personal on the flats and climbs. The burden alone will appeal to some gravel weight-weenies. However its most excellent characteristic could be the snug journey the GS1 provides at a race tempo.
Rolling exhausting on gravel, I wasn’t holding the bars for pricey life; I used to be in management, driving the bike and looking out forward. We take these items with no consideration on a journey, 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 effectively on the street and trails, however gravel is the place it’s residence.
