The Lightest Tour De France Bike? NEW Cervélo R5 Spotted And Weighed

This video contains paid product placement for Abus. A NEW Cervélo R5 has been spotted at the 2025 Tour de France.

Subtly integrated and hiding in plain sight at Visma-Lease a Bike’s hotel in Lille, there’s a host of new features on this bike that take weight weeniesm to the limit of the UCI rules.

In this video, we reveal how Cervélo is pushing the boundaries of the rulebook, how Matteo Jorgenson sets up his race bike and how much it really weighs!

We’re here at the 2025 Tour to France with Team Visma Lisa Bike. Let’s go check out some of their bikes. But first, a big thanks to Abbus for sponsoring this section of the video. Abbus offers highquality and attractive cycling helmets designed for racing, off-road, the city commute, and the family bike ride, as well as a whole range of bike locks and security devices. Hit the link below to find out more. Right, so we turned up a Visma Lisa bike expecting, hoping to see a new S5. And hell, what have we got? We’ve got a new R5 instead. Absolutely incredible. So, this bike belongs to Mateo Jorgensson. And the team tells me that this bike has been designed specifically to hit 6.8 kilos in any size. Absolutely ready to ride, including bottle cages, pedals, and computer mount, bike computer, everything you need. Now, obviously, it looks pretty similar overall, but the fellow engineers have told me that basically every tube on this bike has been changed or modified in some small way just to save off those final extra grams. So, for example, the Squovel Aerfor tube shapes are slightly slimmer overall. You can see this head tube isn’t quite as deep as before, and the little uh interfacing point between the fork and the down tube has also been refined over here on the fork, which you can’t see from there, but we’ll cut in some footage. The uh brake mount now, the bolts go through directly through the front of the fork, straight through to the brake at the back, which just saves a little bit of weight, apparently 30 g, by not needing aluminium inserts in the fork that the bolts thread into. At the rear of the bike, you can see those pencil fin seat stays. Now, the UCI rules dictate that you have to have 10 mm seat stays. Now, SLO says that these seat stays are actually produced to be under that, but with paint just hit the UCI rules of 10 mm. And apparently, there’s a little bit of tolerance there. So, if they can, they go even narrower just to eek out that extra bit of compliance and weight saved. We’ve also got a brand new seat post at the back. It still retains that kind of D arrow shape and obviously there’s plenty of it exposed on this bike. It just helps with comfort. But apparently Sello has moved the top tube up just a little bit because they felt some of the riders felt that the old model was just a little bit too flexible at the rear with lots of seat post exposed. Now up front we also have a new one piece cockpit with a super light design. And what’s really interesting about this is they’ve kind of taken away some of the hardware around the bolts. There are of course titanium bolts in there, but there’s just a little bit of raw carbon and the bolts thread directly on top of that. So, there’s no like aluminum insert to add weight. Apparently, it is also more aerodynamic than the old two-piece setup, saving around 2 watts at a kind of unspecified speed, but we imagine it’s around 45 kph. On this specific bike, it’s got a tiny little Garmin edge computer to rather than a big 1040, which is obviously going to help save a little bit of weight. So on this bike, Jorgensson’s running the Reserve 4249 wheels. So that’s a pretty standard mid-epth allaround riding wheel set. Not a kind of super light wheel set designed just for the mountain days. So that’s kind of interesting. And they are the uh Victoria Corser Pro wide tires which come in at 29C. And we’ll measure those for you in just a minute. So it’s not a kind of super light climbing wheel setup. So it’ be really interesting to see if this size 56 or maybe a 58 does indeed come in at 6.8 8 kilos as Seello is so keen to say it does. So in terms of group set, of course, Vizma Lisa bike are running the latest Stram Red Access, which was the lightest road bike group set available until Campanola launched Super Record 13 recently. Jorgensson is running 5441 to chain rings with what looks like a 10 to 36 cassette out back. Now, of course, if the UCI’s trial gearing restriction regulations do come into effect after the trial this summer, won’t be able to run that next year, but still legal for the time being. So, of course, he is going to run it at this year’s tour. He also has his Wahoo Speed Play Aero pedals there. There’s a Pro Logo saddle up top and of course tax bottle cages from their sponsor, Garmin. So, last few little details. It’s also got a Stram UDH hanger out at the rear to give it compatibility with any future UDH group sets. Vizmissa bike are like last year also running waxed chains on their drivetrains. And Sevel tells me that this bike has had an updated fit geometry to now be much closer if not identical to the S5 so that when the riders are transferring between it, it’s a little bit of a more seamless transition. And what’s really interesting, this is such a pro bike, the first bike we’ve seen at this year’s tour and obviously has a massive stem. Looks about 13 or 14 cm and what looks like a pretty narrow handlebar. So, let’s measure that right now. All right. So, in terms of handlebar width, it looks like we’ve got roughly a round a 37 cm wide handlebar and what looks like a Oh, wow. Maybe a could be a 150 mil stem. That’s obviously extremely long. Now, Jorgensson is a tall rider, but this isn’t a massive bike, but 140 150 mil stand paired with a fairly narrow handlebar. Let’s just check those measurements in between the hoods cuz we know the UCI isn’t going to like this for next year. Maybe just this might just be legal next year cuz it’s measuring around 32 cm in between the hoods. So, let’s weigh it. Now, normally to be fair, we would take the bottles off, but so confident as that we’re going to weigh it with the bottles on. So, let’s see. [Music] It’s taking forever to settle. Oh my god. There you go. So, this one’s coming in at 7 and 30 g. So, not quite 6.8 kilos, but I think once you take those bottles out, it’s going to be pretty much bang on. And obviously, this isn’t the smallest bike here. So, in even smaller sizes, it will of course be even lighter. One little interesting detail that I’ve just noticed whilst we’ve been taking our pictures is that Jorgensson is on 165 mm cranks. Now, that has been a clear trend in the Prop Pelaton of recent years, but obviously Matio Jorgensson’s not a small rider, so 165 mm is pretty short. So, there you have it. Matteo Jorgensson’s brand new Sella R5 at the 2025 Tour to France. Let me know what you think about it in the comments below, and stay tuned for more tour content in the coming days.
