Graeme Obree (born 11 September 1965), nicknamed The Flying Scotsman, is a Scottish racing cyclist who twice broke the world hour record, in July 1993 and April 1994, and was the individual pursuit world champion in 1993 and 1995. He was known for his unusual riding positions and for the Old Faithful bicycle he built which included parts from a washing machine. He joined a professional team in France but was fired before his first race. Obree has created some radical innovations in bicycle design and cycling position but has had problems with the cycling authorities banning the riding positions his designs required.
Obree had built frames for his bike shop and made another for his record attempt. Instead of traditional dropped handlebars it had straight bars like those of a mountain bike. He placed them closer to the saddle than usual and rode with the bars under his chest, his elbows bent and tucked into his sides like those of a skier. Watching a washing machine spin at 1,200rpm led him to take the bearings, which he assumed must be of superior quality, and fit them to his bike. Obree later regretted admitting to the bearings experiment, because journalists referred to that before his achievements and other innovations. Obree called his bike "Old Faithful". It has a narrow bottom bracket, around which the cranks revolve, to bring his legs closer together, as he thought this is the "natural" position. As shown in the film, he thought a tread of "one banana" would be ideal. The bike has no top tube, so that his knees did not hit the frame. The chainstays are not horizontal to the ground. Thus the cranks can pass with a narrow bottom bracket. The fork had only one blade, carefully shaped to be as narrow as possible. A French writer who tried it said the narrow handlebars made it hard to accelerate the machine in a straight line but, once it was at speed, he could hold the bars and get into Obree's tucked style. At a high enough speed, [I could] tuck in my arms. And, above all, get in a very forward position on the bike, on the peak of the saddle. The Obree position isn't advantageous simply aerodynamically, it also allows, by pushing the point of pedalling towards the rear, to benefit from greater pressure while remaining in the saddle. You soon get an impression of speed, all the greater because you've got practically nothing [deux fois rien] between your hands. Two other things I noticed after a few hundred metres: I certainly didn't have the impression of turning 53 x 13, and the Obree position is no obstruction to breathing. But I wasn't pedalling at 55kmh, 100 turns of the pedals a minute, yet my arms already hurt.

What inspired the change?

Once is a 2007 Irish romantic musical drama film written and directed by John Carney. The film stars Glen Hansard and Marketa Irglova as two struggling musicians in Dublin, Ireland. Hansard and Irglova had previously performed music as the Swell Season, and composed and performed the film's original songs. Once spent years in development with the Irish Film Board and was made for a budget of EUR112,000.
Once was met with extremely positive reviews from critics. Upon its March 2007 release in Ireland, RTE's Caroline Hennessy gave the film 4 out of 5 stars and termed it "an unexpected treasure". About the acting, this Irish reviewer commented, "Once has wonderfully natural performances from the two leads. Although musicians first and actors second, they acquit themselves well in both areas. Irglova, a largely unknown quantity alongside the well-known and either loved or loathed Hansard, is luminous." Michael Dwyer of The Irish Times gave the film the same rating, calling it "irresistibly appealing" and noting that "Carney makes the point - without ever labouring it - that his protagonists are living in a changing city where the economic boom has passed them by. His keen eye for authentic locations is ... evident". In May, on Ebert & Roeper, both Richard Roeper and guest critic Michael Phillips of the Chicago Tribune gave enthusiastic reviews. Phillips called it, "the most charming thing I've seen all year", "the Brief Encounter for the 21st century", his favorite music film since 1984's Stop Making Sense and said, "It may well be the best music film of our generation". Roeper referred to the film's recording studio scene as "more inspirational and uplifting than almost any number of Dreamgirls or Chicago or any of those multi-zillion dollar musical showstopping films. In its own way, it will blow you away." Once won very high marks from U.S. critics; it is rated 97% "fresh" by the film review aggregation site Rotten Tomatoes and scored a grade of 88 ("universal acclaim") according to Metacritic. In late 2007, Amy Simmons of Time Out London wrote, "Carney's highly charged, urban mise-en-scene with its blinking street lamps, vacant shops and dishevelled bed-sits provides ample poetic backdrop for the film's lengthy tracking shots, epitomised in a sequence where the Girl walks to the corner shop in pyjamas and slippers while listening to one of the Guy's songs on her personal stereo. With outstanding performances from Hansard and new-comer Irglova, Carney has created a sublime, visual album of unassuming and self-assured eloquence." The Telegraph's Sukhdev Sandhu said, "Not since Before Sunset has a romantic film managed to be as touching, funny or as hard to forget as Once. Like Before Sunset, it never outstays its welcome, climaxing on a note of rare charm and unexpectedness." The film appeared on many North American critics' top ten lists of the best films of 2007: In 2008, the film placed third on Entertainment Weekly's "25 Best Romantic Movies of the Past 25 Years".

Is there anything worth noting about the visuals in the film?
