Highway bikes have after all modified an enormous quantity within the final couple of many years, however trying again at this traditional Big MCR from 1997, arguably one of many first really aero road bikes, reminds us simply what an thrilling interval the Nineteen Nineties was for bike improvement, when the foundations weren’t to be adopted, however really bent and damaged.
Again in 2019, at the beginning of a street.cc rideout exterior our Tub workplaces, our senior tech author on the time David Arthur noticed somebody rock up on one in all these uncommon beasts. It definitely received everybody speaking, and regardless of a lot speak of twitchiness when attempting to deal with the large slab of carbon monocoque between your legs, it nonetheless gave the impression to be doing the proprietor proud.
A little bit of historical past: the Big MCR was launched just a few years after the beautiful Lotus Sport 108, which Chris Boardman famously rode to Olympic victory in 1992. Each had been designed by the late, great bicycle engineer Mike Burrows, and each tore up the traditional bicycle design ebook of the time.
A street model of the Lotus, the Lotus Sport 110, adopted the observe bike with provision for gears and brakes, and it’s this bike that the Big branded MCR relies on. Burrows labored for Big within the 90s, serving to to develop the corporate’s TCR compact body design, revolutionising the trendy street bike within the course of.
Sadly, the novel design and the pace of the Lotus shocked the UCI a lot that they introduced in new technical guidelines that outlawed the design, making certain that every one bikes developed since retain the traditional double diamond look of a street bike. In 1996 – and sadly for Big, simply earlier than the discharge of the MCR – the UCI unleashed Precept 1.3 on the world to set this in stone, making certain future bikes of the peloton remained roughly in double diamond type.
Within the UCI’s newest clarification guide of its technical laws, it summarises the precept like this: “The UCI Laws assert the primacy of man over machine. Observance of the laws by all events concerned facilitates sporting equity and security throughout competitors.”
Anyway… the MCR body is a full carbon fibre monocoque with matching carbon fork, with (principally) inside cable routing, an aero seatpost and a single water bottle mount.
Whereas it does look slightly much like the Lotus bike, the single-leg fork and single chainstay had been exchange with extra typical components so a groupset and brakes might be fitted for using on the street.
Big produced the MCR for simply 4 years, starting in 1997 with a top-tier MCR 1 and second-tier MCR 2. The MCR1 was black and purple, so the one we noticed 4 years in the past was a 2 that got here with a 9-speed Ultegra groupset.
It’s a heavy bike by in the present day’s requirements, with a claimed 9.9kg full weight when specced with the Ultegra groupset and carbon spoked wheels, additionally designed by Mike Burrows. It value £2,000 in 1997, which might be round £3,748 in in the present day’s cash.
There is not an enormous quantity of info on the market on the Big MCR, however there’s an owner’s club on Facebook, and we managed to talk briefly with a type of proud homeowners. Tirivanhu Dzivakwi (above) had this to say about his MCR that he rides repeatedly across the backroads of Harare:
“I received the body and fork from a buddy in 2021 and needed to rebuild it.
“This bike is secure and quick in comparison with my Raleigh Microsoft carbon. The second I began utilizing this bike my common pace elevated tremendously. I used to common 21 to 24km/h, however with this one I twice managed to hit a median of 31km/h.
“I have not tried it with finer wheelsets and am assured it is a superbike. With a very good groupset will probably be a bullet.”
A contented MCR proprietor certainly!
So, why the explosion of unconventional frames within the 90s anyway? Basically it was born out of the elevated use of carbon fibre by bike designers. When Greg LeMond proved the worth of aerodynamics in 1989, carbon was in its infancy, however bike designers noticed big potential to create body shapes beforehand unimaginable with steel. Carbon enabled better freedom to supply aerodynamically superior frames that diminished drag and elevated the pace a bicycle owner might journey at.
Due to the pesky UCI, arguably nothing too radical has occurred on the planet of street and time trial bike design past cables disappearing, weights dropping and disc brakes showing (thus weights going again up once more) for the reason that late 90s – however the elevated reputation and funding into the UCI-free sport of triathlon has led to a glut of radical and unconventional frames for the reason that mid-2010s, such because the “mind-bending” Cervelo P5X, Diamondback’s MotoGP-inspired Andean and the bike within the image above, the Cadex Tri.
The Cadex Tri was used with nice success by Kristian Blummenfelt to win the Ironman World Championships in 2022, and you may clearly see the essential form of the body is strikingly much like the MCR. Is that this strong proof that the MCR’s body form really was quicker than any double diamond aero street body being manufactured in the present day? If just like the UCI you imagine in man (or girl) over machine, possibly the ban wasn’t such a nasty concept in any case…
