Muc-Off’s Lightweight Oversized Precision Shifting (L.O.P.S) is an oversized pulley wheel system proved in scientific tests to be lighter and stiffer than its leading competitors. It made its world premiere in the pivotal individual time-trial stage on the penultimate day of the 2020 Tour de France.

The system, which unites a highly advanced titanium body with supremely efficient coated pulley wheels and bearings, was used by Team Bahrain McLaren leader Mikel Landa on Saturday September 19 2020 as he made his final push for a place on the podium in Paris a day later.

L.O.P.S is an oversized pulley wheel system developed by Muc-Off’s scientists and engineers in partnership with McLaren. Comparative tests conducted using the sophisticated equipment in the new, leading-edge laboratory at the brand’s headquarters in Poole, Dorset, confirmed it as the lightest and stiffest of any of those selected from leading competitors.

The titanium body is created using a sophisticated additive manufacturing process. The pulley wheels (13t upper, 19t lower) are made from aerospace grade aluminium and finished with a supremely efficient coating that delivers friction coefficients over three times lower than hard anodised equivalents.

The bearings were manufactured to aerospace level specification. The size of the bearing used was optimised for the number of rolling elements and application speed to help reduce frictional losses. Ceramic rolling elements are lubricated with a special synthetic hydrocarbon to further reduce the coefficient of friction and tighter radial and axial tolerances improve shift accuracy.

Optimised specifically for the individual time-trial, the final piece of the puzzle to help maximise performance, was the lower sealing requirements, which led to further bearing drag reductions and to incorporate highly compatible material expansion rates.

Tats a bit of over-reacting from Trek right?
Just a simple bye.
and it is a freedom of speech country.

btw... his beard not so aero dynamic

I think it is a PR move. Cyclists are mostly left winged slant and with from what I heard happened in the presidential debate, even though Biden was bad, Trump was worse and did not want to condemn White supremacists.

So anyone associate themselves with Trump will naturally be perceived as a racist.

Correct but they did not terminate his contract from what I heard.

Plus Trek still has damages to repair since the Lance Armstrong days and in addition to that, they need to sell bikes and most people all over the world dislike Donald Trump, especially the Chinese

Well.... yeah understandably they need to stay neutral, like all other major brand.

Anyway- casual topic.... are we looking at the trend of tyre size going up?
last time down to 23mm... now popular is 25mm and heading towards 28mm?

logic ka... large diameter less resistant?

not to say less resistant, but from what i heard slightly larger will allow more contact patch for better braking wor.... especially with disc brakes.

apart from that, larger width = lower air pressure = better comfort (though i doubt it made any difference lol)

I'm using Vittoria 28C but still feel nicer rolling with 100psi.

the theory is supposed to be that narrow super high pressure tires causes a lot of bumping around when you're on the actual road itself, and this contributes a lot to power loss.

I reduced to 90 PSI from 100 on a 25c (my rims are 21, so the tires actually look like 28), and noticed that there's less effort to maintain speed
