An exclusive from us 👀

Professional cyclists across several WorldTour and ProTeam squads are trialling a breath-holding hypoxic training system to try to simulate altitude training using an app called Redplus Performance.

An interesting step in the journey for physiological gains, and particularly around the increasingly complex landscape of hypoxic training methods.

Lael is legitimately the coolest person I have ever met. I really hope she takes the record 🙏

I’ve become totally obsessed with this Korean Aloe Vera drink, but I’m increasingly aware that on video calls it looks like I’ve started hydrating exclusively with aftersun…

The SL9 leak story arc has been my a real gem. It seems likely we'll see it fully break cover at the Dauphine 👀

@dnlbenson Fair enough, I hadn’t seen those. Chris’s analysis is still really excellent and worth a read.

Japan should be a major force in the world of professional cycling; with big cycling companies, lots of young people getting into the sport and a healthy race calendar 🇯🇵

So why are there no Japanese riders or races in the WorldTour?

The UCI minimum weight rule is a total anachronism that effectively achieves nothing in terms of rider safety - its main purpose.

The sport and industry would both be better off if it was abolished 👇

Lorena Wiebes’ 20-gram disqualification shows the UCI's minimum weight rule should be abolished

I think lowering weight at this point comes up against quite major physical barriers. Light frames only weight 600-700g, there's only so much more weight you can take out of that before it's literally no longer there, and rigidity is often more important to riders than weight.
Groupsets are relatively heavy but I couldn't see riders trading to super light groups at the cost of shifting performance.

[Peter Stuart @PeterStuart3]

I think that is an important part of any equipment regulations, but I'd say that in 2026 the arms race is around aerodynamics rather than weight. If the weight limit were removed Pogacar would probably still ride a bike above 6.8kgs.
You can also get some very cheap very light bikes on AliExpress 😂

[Peter Stuart @PeterStuart3]

@AllAboutCyc1ing Bikes and components already have to meet recognised safety standards if they’re going to be sold, and UCI approval adds another layer of verification for equipment used in racing.

So what difference does restricting the weight make?

[Peter Stuart @PeterStuart3]

@NordBob I suspect there will be an appeal and some serious questions to answer about the rules and process. But yes, damage done for Wiebes sadly.

[Peter Stuart @PeterStuart3]

This is going to be a marathon, not a sprint…

I will be surprised to see the UCI win this one.

Verklaring Team SD Worx – Protime na diskwalificatie Lorena Wiebes

Team SD Worx – Protime is verbijsterd over de beslissing van de UCI-jury dat de fiets van Lorena Wiebes na de eerste etappe van de Giro d’Italia Women niet voldoet aan de minimale gewichtslimiet volgens artikel 2.12.007–2.2. Volgens de jury woog de fiets 6,78 kilogram en voldeed deze daarmee niet aan de door de UCI vastgestelde ondergrens van 6,8 kilogram.

De ploeg plaatst vraagtekens achter de meetcontrole van de fietsen in de Giro d’Italia Women. Zo was er een gewichtsverschil van meer dan vijftig gram tussen de eerste en de tweede weging van de fiets van Wiebes na afloop van de rit in Ravenna.

Wiebes heeft gedurende dit seizoen meerdere malen met deze fiets gereden, die steeds op dezelfde manier is afgemonteerd. Met deze fiets behaalde zij vele overwinningen. Bovendien is de fiets eerder dit jaar na afloop van meerdere wedstrijden, die door Wiebes in de sprint met groot verschil werden gewonnen, door de UCI-jury gewogen. Daarbij bleek telkens dat het gewicht van de fiets ruim boven de grens van 6,8 kilogram lag. Het team begrijpt daarom niet hoe het mogelijk is dat diezelfde fiets nu onder de gewichtslimiet uitkomt.

Team SD Worx – Protime is van mening dat de diskwalificatie van Wiebes een buitengewoon zware sanctie is. In een vlakke sprintrit, in tegenstelling tot een bergrit, levert een gering gewichtsverschil nauwelijks voordeel op. Zeker niet voor een renster als Wiebes, die in Ravenna met drie fietslengtes verschil de sprint wist te winnen.

Team SD Worx – Protime, al vijftien jaar een toonaangevende ploeg binnen het vrouwenpeloton, heeft dan ook geen verklaring voor het feit dat de fiets van Wiebes ditmaal deze gewichtscontrole niet heeft doorstaan.

[Peter Stuart @PeterStuart3]

@NordBob I agree, I'm perplexed.

[Peter Stuart @PeterStuart3]

I'm still so surprised by Wiebes expulsion. So few bikes in the pro peloton are even marketed as sitting below 6.8kgs as weights trended upwards as disc brakes were introduced.

It feels so 2013... there will be a lot more to come from this story.
