Jeffrey Hoogland set a brand new global list within the Kilometre time trial this week with a time of 55.433 seconds, beating the 10-year-old list by way of nearly a 2nd – an enormous margin within the self-discipline – which was once prior to now held by way of France’s François Pervis.
The four-time International Kilo champion was once up at the list at each cut up which came about on the Velodromo Bicentenario in Aguascalientes, Mexico. Hoogland additionally made a few unplanned makes an attempt at the 200m global list after the kilo however overlooked it by way of round .100 of a 2nd in any case.
The record-beating Koga Miyata observe motorbike Hoogland used has some fascinating touches within the quest for all-out pace. We have now taken a better take a look at the system and feature were given some within wisdom and tech insights from Tim de Boer – head mechanic for the Dutch Olympic observe biking group for the closing 13 years.
Observe motorcycles have most often been getting extra excessive in look in recent times and we have lined a number of wild designs prior to now and be expecting extra within the run-up to the Paris Olympics as countries push for the utmost imaginable merit at the forums. We lined an much more radical Hope / Lotus Staff GB observe motorbike in July, a brand new Kickstarter challenge from Stromm, a Glance and BMC, in addition to the TRED X23 that Argentina had been driving on the Glasgow Worlds.

Dutch athletes have used Koga motorcycles for years now at the observe, and Hoogland’s system is constructed up round a Koga Miyata Kinsei measurement massive body. The Kinsei is to be had as a frameset and will best be ordered with the Kinsei cockpit. The whole worth for the frameset and dropped Kinsei handlebar is €9,499. De Boer advised us that even supposing the Kinsei body sizes are indexed as S-XL, the geometry is all according to research and comments from the Dutch nationwide group, so even supposing they bring about free measurement labels the geo may be very customized. For example, a measurement small body occurs to be longer than a medium.
Hoogland used Dutch Dugast tubular tyres, now not like Fillipo Ganna who used Continental tubeless tyres for his hour list try. The Dugast tubs in query are the Pisa Latex fashions which function silk casings and lift an £84.99 retail worth in keeping with tyre. Pressures for the list had been an enormous 14 bar or 200 PSI for the 20mm entrance / 23mm rear tyres. It sort of feels slender nonetheless trumps wider and softer at the tyre entrance within the managed setting of the velodrome the place natural pace is vital.
I requested De Boer about sticking to tubs over tubeless and he defined that for a formidable and heavier sprinter coming into a banking at round 84pkh (which was once Hoogland’s max pace right through his journey) having sufficient air in a tubeless tyre to stop it from deforming and even burping could be difficult and now not one thing they sought after to gamble on. He did give an explanation for, on the other hand, that they’re taking a look into tubeless tech for the longer term.
A mixture of wheels was once extensively utilized for the record-breaking journey with a Mavic Comete entrance disc wheel getting used (the Rio version) and a rear Campagnolo Ghibli disc which were de-stickered and the wheel nuts changed with black Runwell ones. The tough overall of each disc wheels is round $5,375. I believed the combination of disc wheels is in an effort to succeed in most aero get pleasure from the body and wheels as a bundle, however it seems that, the riders choose the dealing with traits supplied by way of the entrance Mavic wheel which has a somewhat other form.
The motorbike setup was once in reality similar to what Hoogland would normally run and what he has used on the Tokyo Olympics and so on. De Boer defined one key exchange got here from the handlebars.
Hoogland makes use of a years-old Professional Missile base bar which is favoured because of its stiffness however the group not too long ago paired it with new Speedbar time trial extensions. De Boer defined the Speedbar’s customized nature does away with a large number of wedges and shims you ceaselessly have to make use of to reach the right kind place for a rider, which aids stiffness and reliability. Significantly, Speedbar founder Edwin van Vugt is every other of the Dutch Nationwide Federation’s longtime mechanics.
A C-Undergo backside bracket was once used in addition to the inventory Campagnolo bearings which de Boer defined are already excellent and most likely CeramicSpeed entrance bearings within the Mavic disc, regardless that de Boer wasn’t utterly certain. I anticipated a large number of taking out bearing seals and flushing out grease to be occurring, however I assume this highlights how just right one of the most absolute best bearings are already.
Drivetrain-wise, Hoogland used a monster 70×15 tools combo with a customized carbon chainring from Digrit. The chain was once a YBN SLA410 fashion with Molten Pace Wax chain wax and race powder which you’ll examine in our absolute best chain wax information. The sprocket was once from Euro Asia Imports.
Except for prep like chasing backside bracket threads and going through the bb shell, De Boer stated it does not obtain any particular remedy to deal with Hoogland’s superior energy output however he defined he does generally tend to check up on parts to ensure there aren’t any disasters or harm inflicted by way of a status get started.
