Nekaj besed gostujočega ležečega kolesarja… Sjaak Bloemberg piše:
“When I heard that the Human Powered Vehicle World Championship was going to be held in Milan, Italy, I decided that it was a nice opportunity to visit a cycling friend in Milano, see more of Italy and of course enjoy the nice recumbent community and experience their high performance races.

My plywood bicycle is the most suitable recumbent I own to do both races and travelling. For this championship I removed unneccesary options like front gearing and luggage rack and I mounted high pressure racing tires.
Being dissatisfied with the stiffness of the front boom I also improved its stiffness less then one week before competing. The nice thing from the plywood frame material and the sandwich construction is that you can easily modify it. After a few computer calculations (CAE) I decided where adding extra material was most efficient. By adding about 250 grams of plywood inside the frontboom (mostly near the steerer tube) the stiffness was noticably improved.
During the 50m dragrace the stiffness was given a stress test and to my surprise and also to the surprise of the other contestants and public I managed to get a 2nd place on this discipline of the World Championship. On the 200m sprint (flying start) I improved my personal record to an average of 59,7 km/h (was 55,8). The other races I just enjoyed and performed OK for me personally.
