This Equator Sensei G4 neatly combines classic titanium bike style with modern fast gravel bike performance tech. And it does both at a reasonable price point to create a well-refined evolution of an all-road-inspired gravel bike that still packs enough tire clearance to make it plenty versatile for everything from road to bikepacking adventures. If I could only have one gravel bike, this is the kind of bike I would want.Plus, after Equators headquarters and workshop burned to the ground just a couple of months ago, they are already bouncing back strong. And they have a very limited edition of this bike, their more adventure-focused Yasei, and a couple of wavy carbon wheelsets commemorating the historic Building 34 that they used to call home!2026 Equator Sensei G4 titanium gravel bike(Photos/Cory Benson)A few years back, I previewed Czech wheel & bike brand Equators two affordable titanium gravel bikes, already on their second generation the all-road-leaning Sensei and more adventure-focused Yasei. Then, I spent a couple of years riding the 3rd gen Sensei, even loading it up and riding the bike to the launch of Schwalbes G-One RX gravel tires. It even made my 2024 Editors Choice Award as the best value gravel bike I tested that year. The Sensei is a solid all-rounder for pretty much any mixed-surface riding. Just probably not deep backcountry bikepacking they have the Yasei for that. Or pro-level gravel racing because, lets be honest, everyone wants an aero carbon bike for that anyway maybe even a 32 one from next season, too.The Sensei mixes snappy all-road-like geometry with enough clearance to fit pretty wide gravel tires. It has tons of adventure-ready mounting points. It feels fast on hardpack and roads, but is still plenty stable and predictable when hitting loose gravel fast.And of course, its affordable titanium with framesets from just 2440 & complete Di2 bikes from 6350. For the same price as a mid-level carbon bike, you get the classic forgiving ride of titanium. And a bike that you dont have to be precious with, probably a frame that will last forever.Ride anywhere, in any conditions, on any type of terrain. Then, rinse and repeat.Whats new since the previous generation?new Sensei G4 (left)Most of the fourth-generation updates are really just refinements that Equator has come to, based on rider feedback and their own efforts to optimize their two gravel bikes. For example, the latest Sensei gets a 20mm taller headtube. Even though this is a fast-feeling gravel bike, most buyers of round-tube ti gravel bikes arent looking for a slammed road cockpit position. I rode gen 3 with 25cm of spacers under the stem, with a pretty aggressive fit. Now, I could go with fewer spacers, which also frees up more space in the main triangle for a bigger partial frame bag above my big 1L Zfal bottles. Anyone who wants to get lower can still #slamthatstem, or even fit a steeper stem too, if needed.new Sensei G4 (front)The G4 Sensei also uses incrementally smaller but no longer butted seatstays, which Equator says had no impact on weight or comfort, but seems to have improved lateral stiffness. Having ridden both generations, I couldnt notice any loss in compliance. The straight ti stays still soaked up plenty of gravel chatter.Equator Sensei g3 with Ortlieb Quick-Rack out back & Jack The Rack up frontAnother small but functional change: the rear rack mounts are now in line with the rear axle, meaning they point out perfectly sideways. Its a minor change vs. the previous rack mounts, which had been perpendicular to the seatstay itself. But the update means mounting for removable racks like the Ortlieb Quick-Rack that I used is now much smoother & easier. Perfect for having a rack, then quickly taking it off, leaving just its small mounting posts.Updated cable routingnew Sensei G4 (front)One of the only things I didnt really love about the previous generations of this frame was its routing, first in the downtube then through the side of the headtube. Theoretically, I dont want to love fully-integrated cable routing through the headset. But on a bikepacking-ready gravel bike, it just makes sense. Conventional internal routing just doesnt play nicely with a lot of handlebar bag setups. Going fully internal looks tidy, but also means your cables arent in the way of bags. Yes, setup takes longer, as does replacing/upgrading a groupset, for example. Yes, replacing a headset (which youll only do every few years) becomes extra work.Continuing the fully internal thing, the rear shift cable is also now fully enclosed in the chainstay, where it used to be partially exposed through its machined chainstay yoke behind the chainring. That yoke is now 3D-printed ti, allowing it to be hollow, better protecting your shift housing.Other routing updates include a new hole in the seattube for 2x Di2 compatibility, and a cleaner hose exit on the left chainstay for the rear brake line.Tech details3Al-2.5V seamless, butted titanium framefull carbon, tapered steerer fork (adventure fork with 3-pack mounts available, on request)integrated fully internal cable routing through the headsetovalized toptube & chainstays, CNC-machined headtube with engraved logo, plus 3D-printed chainstay yokesize-specific seatstays tuned to typical rider weight ranges (16mm on my M, vs. 17mm on L)oversized 3D-printed T47 threaded bottom bracket with removable access door for easy routing away from the BB axleUDH, T-type compatibility1x and 2x compatible, when used with band clamp front derailleurmechanical or electronic drivetrains, including Di2 wiring ports flat mount disc brakes12mm thru-axles31.6mm seatpost with internal dropper routing for a droppertitanium classic seatpost clamp included2 cage mounts inside front triangle (3-bolt on downtube), plus toptube bag & under downtube mountsrear rack and fender mountschain hanger pin on the inside of the driveside dropout47mm official max tire clearance (which is quite conservative)4 frame sizes available (S-XL)1850g frame weight (size M) and 480g fork weight (uncut), claimed9.64kg actual size Large, GRX 2x Di2 complete bike weight (with 320g pedals)OK, but how does the Sensei G4 actually ride?Sensei G3I rode gen 3 for more than two years as my baseline gravel test bike, on 40-50mm tires mostly. It was one of, if not the most comfortable of gravel bikes Ive ridden in the past few years. Plus, it never felt like I was sacrificing speed or nimble handling for the all-day, all-terrain comfort. new Equator Sensei G4Now, Ive only ridden the new Sensei G4 for just one month. But the ride was very familiar, virtually the exact same feeling of comfort balanced with all-road-leaning agility.At the heart of that is all-road-inspired geometry. Riding a Large-sized bike, I get a 72 headtube and 73 seat angles, 430mm chainstays, a pretty short 379.5mm Reach, and average 607mm Stack height, even with a longer headtube in this generation. Its definitely a bit more compact than most modern gravel race or gravel adventure bikes Ive ridden recently, giving it a more agile sense.I do appreciate the fast & snappy feel. But it should be noted, the Sensei does require paying attention to the ride. (Equators Yasei is much longer and more relaxed, for anyone looking for more of an adventure bike.)Riding fast and looseEven though the geo leans roadie, I feel like its actually best for an already technically capable off-road rider. For pretty much any gravel bike with fast, aggressive road-inspired geometry, you should probably be comfortable riding on the edge of your seat, or the edge of control, before you head off onto techy terrain at high speeds.But thats kinda what I love most about this bike. It goes fast and handles a bit like a road bike. But it also has that unmistakable give and forgiveness that you get from the natural damping character of a round-tube titanium bike.Basically, the Sensei ride was effectively indiscernible from the previous generation. Thats a good thing; really only the seatstays changed. But now it gets much improved integration. The Equator Sensei offers a solid balance of all-around comfort and quick handling. Just like the previous bike, swapping wheels and tires around let me fine-tune the bike to how I wanted it to feel, and where I wanted to ride on the day.Wheels & tires make all the differenceThe test bike arrived for me with 40mm Tufo Gravel Speedero tires mounted to Equators own 21mm internal Wavy 35 carbon wheels. A nice and durable setup, well suited to fast riding on mostly smooth and hardpack surfaces. But maybe not getting the most out of this bikes versatility. So, I also swapped in a set of the big aero WTB Course 52 tires on 27mm internal Rose GC50, still with 4-5mm clearance where it really matters (a bit closer at the front derailleur cage in the smallest gear). The bigger tires and subsequent lower tire pressure delivered tons of grip and more comfort over rougher tracks, while admittedly losing a bit of the bikes precise handling at higher speeds on the road. My real takeaway, though, is again how the Sensei can be such a great platform for however you want to ride gravel. You just have to tailor it to what you are looking for. Now look, it doesnt fit 58mm tires. And it isnt an aero gravel race bike. If thats what you are hoping for, look elsewhere.But if you are hunting a quick gravel all-rounder, you really cant go wrong with this latest Equator Sensei G4.Equator Sensei G4 Pricing, options & availabilityGetting its upgrades first, the 4th-generation Sensei is the most up-to-date of Equators titanium gravel bikes. The adventure Yasei is likely to get a G4 update next year.The Yasei is available as both an S-XL frameset starting at 2415 (a few bucks cheaper than when it officially debuted three years ago). And complete bike builds from 4431 with mechanical GRX, or from 6044 with GRX Di2. Now looking at availability, normally Equator keeps several of their frames in stock, ready for quick complete bike builds. But their workshop and warehouse stock literally burned to the ground at the start of July. And theyve been rebounding ever since. So, itll be a tiny bit longer than usual.Never Not Rise Again(Photo/Equator)And thats where Edition 34 comes in. A small family-run wheel, then bike company based in the eastern half of the Czech Republic, Equator was headquartered in a historic industrial building in Zln. That is, until the historic 1950s building 34 of the Baa shoes factory complex burned down over the first week of July. It literally took more than a week to extinguish the 10-story industrial building, but thankfully no one was injured by the long-smoldering blaze.Back on their feet after a lot of local support (before insurance will hopefully kick in, probably next year), Equator hasnt given up. Instead, theyve continued their plans to update their existing models (and introduce a few new ones in the near futurehint, hint ti MTB hardtail and 32 gravel in the works!) And theyve got a special commemorative 34 Edition of their gravel bikes, with low-key 34 edition graphics bead-blasted on the ti frames.Limited Edition 34 Fire SalePricing is exactly the same Equator isnt trying to cash in, just to commemorate an unexpected milestone in their company history. There are just some extra one-time graphics, with the note Never not rise again from the ashes note on the chainstay. Equator dont expect to make huge numbers of these 34 Edition bikes. But they want buyers who supported them in this difficult time to be able to remember what they overcame together, with the communitys support.(Photo/Equator)Officially, Edition 34 started at the end of September, and runs through the end of October. But weve been told it will likely extend for at least the first week of November, too, as October ends in the Czech Republic with an extra-long national holiday weekend.Edition 34 bikes ordered during the promotion, as well as regular orders, will be delivered in April of 2027. That extra-long lead time is to answer the fact that all of Equators stock burned to the ground over the summer, as did their actual place of work. And theyre still getting back on their feet, back to delivering customer orders from the summer, servicing existing bikes & wheels, and now finally taking new orders again.Equator-cycling.com
