60:aday and Pegoretti Cicli launch Italian based frame building school
Pegoretti Cicli and tour organisers 60:aday are launching what they claim to be the first ever Italian-based frame building school, enabling a limited number of people to get a hands-on experience of how to build a bicycle frame.
To be held at Pegoretti's workshop in Trento, Italy, and taught by one of the real masters of Italian frame building, Dario Pegoretti, the school will take place over seven days in June and July and will give an insight into the mysteries of frame building, covering topics such as biomechanics, material selection, frame geometry and general hands on frame construction.
Once the course is completed, the students will have a bare frame ready to be painted.
The cost of the course is €4450, with two start dates, June 29 and July 13.
Yeti Europe / IRWIN Race Team

Other sponsors include Roach Clothing, SPY Optics, RaceFace, Stunts.org.uk, Chris King, Evolution Imports, Hope, Dianese, SDG Saddles, Atomlab, TF Tuning and Bromley Bike Co.
Compact engine gear-set for bicycles
Denver-based engineer Stephen Katsaros believes that battery-powered bicycles are not the answer to traffic problems, and has designed a gasoline-based Revolution Motor to take their place. While many of us 'proper cyclists' probably think powered bikes aren't the answer either, we can see applications for a power-assisted bike (getting older riders up hills, for example) if only the weight were reasonable, and that's what Katsaros says he's come up with.
"…those (electric) bikes all weigh around 80 lbs and only have a range of 10 to 15 miles. The problem is that it takes about 377 lbs of lead-acid batteries to equal the energy stored in a pound of gasoline," said Katsaros
His Revolution Motor consists of a 27 cubic centimetre two-stroke engine and a gear train that fits the 75mm-wide confines of a conventional bicycle fork. The drivetrain, consisting of six spur gears to achieve three reduction steps, offers a 100:1 speed reduction ratio between the engine and drive wheel and is necessary as the motor runs at such a high speed.
Katsaros believes that using his motor, manufacturers can cut the weight of a motorized bike to about 14 kilograms with a driving range of about 30 kilometres.
