Having my own disc brake woes. Since switching my handlebars my front disc is squealing (probably got some mineral oil some part of the system accidentally). I've managed to get the sequel to be only at the verrrrrrrrrrrry end of the brake pull (like when I'm at like 3mph or less). I've tried everything- clean the rotor with isopropyl alcohol, clean the rotor and pads with finish line disc brake cleaner, wire brush the rotor and pads to scrap any grime off, sand the top layer of the pads off, and torching any contaminants that could be lingering on the pads, all to no avail. My next attempt is to use some Squeal Out (I've read good things about this stuff and the marketing material says it's meant to decontaminate the rotors and clean the system, but a disc brake lubricant gives me pause). Any other ideas out there that before I throw in the towel and start replacing parts?

This is an interesting approach to tubeless flats...

I think it's diabolically brilliant... if it works.

The UCI Management Committee also approved several propositions from the Equipment and New Technologies Commission for modification to the UCI Regulations linked to equipment design. Some of these propositions follow recommendations made by SafeR, the organisation dedicated to safety in professional road cycling. The increasing speed of races and the safety implications of developments in equipment are one of SafeR's main areas of focus. This has been the subject of detailed consultations with teams, organisers and riders, including the distribution of questionnaires to all professional riders and teams.

It has therefore been decided to set the maximum height of bicycle rims for mass start road events at 65mm as of 1 January 2026.

As of the same date, the minimum overall width of handlebars (outside to outside) for mass start road and cyclo-cross events will be set at 400mm, with an inner width of 320mm between brake levers. Meanwhile, the minimum overall width of handlebars (outside to outside) for mass start track events will be set at 350mm as of 1 January 2027.

For bicycles used in the road (as of 1 January 2026) and track (as of 1 January 2027) disciplines, only a maximum internal fork width of 115 mm at the front and 145 mm at the rear (measured along the entire length of the front fork and rear triangle) will be permitted.

The UCI Management Committee approved the introduction of a distinction between road and track time trials on the one hand, and road races on the other, with regard to the helmets that may be used. The specifications for helmets that may be used in the various events will therefore be clarified with effect from 1 January 2026. The UCI Equipment Unit, in consultation with the Equipment and New Technologies Commission, will continue to work in detail on the subject of helmets, both in terms of approval procedures and specifications for the coming seasons. Members also granted the UCI Sports Department a mandate to introduce a helmet approval protocol which will be effective from 1 January 2027 at the earliest.

I hope this doesn’t go through. It’s unfair on smaller women and smaller male riders. I am a shorter person and I really enjoy riding with my 38cm bars on track and road. 40cm feels unwieldy now. That said, I’m also not racing a lot of races with UCI equipment checks.
