WRRA welcomes a new committee member:

Thomas van Schaik has accepted our invitation to become a new records committee member. His experience on the recumbent racing scene and his engineering knowledge give him the perfect background to make rules and decisions on record attempts. His geographic location will provide us with presence at record attempts in Europe which will lead to better universal compliance to rules and faster ratification of records.



An introduction to our new committee member:
Name : Thomas van Schaik
Factory Delivery Date : 30-dec-1975
Place of birth: Leiden, The Netherlands
Introduction:
In 1998 I bought my first recumbent, a Flevo Racer. I just started at the University for Technical Education in Haarlem where I went to study aeronautical engineering, the link was quickly made to the aerodynamic advantages of a recumbent.

Cycling holidays went well from then on, 180km in one day was suddenly no longer a problem, indeed, my first holiday with the Flevo Racer was to the European Championships in Denmark. The first day I drove like 240km, in the evening we played some soccer!
Today I still drive that bike, now almost 120,000 km on the clock.
During my studies I built a Flevo Racer with 2 × 20”. I drove it a couple of competitions. A nice fast bike but still not fast enough. I felt the need for SPEED!

In my last year I did my graduation for J & S Cycle Services (which later became known as Velomobiel.nl). I designed a fully faired bicycle for Ymte Sybrandij to be able to attack the world hour record (at that time Lars Teutenberg in the Whitehawk).

Due to the Dutch weather, and my long commute (40km) I decided to build a velomobile. In order to keep costs low, the tandem was sacrificed and a homemade velomobile was built in 9 months time (a difficult delivery indeed!).

After a couple races at the race track in Zandvoort I decided I needed a faster bike, so I bought a second hand Optima Baron. This bike, over the years, has been modified so that it no longer resembles the original bike.
I still use this bike today, although I am busy with a design out of carbon fiber...

Work:
Since 2000, I work as a Design Engineer for Aircraft Structures with KLM Engineering and Maintenance in the Netherlands.

Currently I am involved as a Team Manager in the “KLM Engineering & Maintenance Knowledge- and Capabilty-level, Aircraft Composites”. This project has close relations with the Commercial Aircraft Composite Repair Committee (CACRC).

Goals:
Podium Place (s) unfaired WK / Cyclevision Tilburg
improvement of current world hour streamlined (Damjan Zabovnik: 54,136 mph or 87,123 km / h) and unfaired (Aura © lien Bonneteau, 50,529 km / h)

Racing:
Record(s) 200m : · 59.1 km/h (12.18 sec - Omnisport Apeldoorn 2009 - Baron TT 2x26")· 100.7 km/h (7.150 sec - 62.57 mph - Battle Mountain 2008 - SpeedHawk I)
Record(s) 1km : · 1:12.6 min (49.6 km/h - Velodrome Sloten 2009 - Baron TT)
Record(s) 1 hour : · 44.229 km/h (Cyclevision Sloten 2008 - Baron TT)
Record(s) 6 hours : · 39.2 km/h (235,2 km - Cyclevision Sloten 2008 - Baron TT)
Bikes : · Flevoracer 2x28" (+/- 120.000 km)· Homebuild Flevoracer 2x20" (+/- 60.000 km) · Homebuild Velomobiel (+/- 70.000 km)· Optima Baron TT 2x26" (+/- 30.000 km)

2009 was a banner year for the World Recumbent Racing association. The effect of the WRRA rules, organization and the web site have led to a significant improvement in performances. Recumbent bike designers, builders and athletes have proven that they are up to the challenge and the seem to be feeding off of each others' success. In particular, the Men's one hour was very competitive in 2009 and in one weekend, the record was increased 3 times.

Records
There are still many open opportunities in which records have not yet been established and we hope that this year, we can start the ball rolling in these categories.

2009 concluded with a record smashing  World Record Weekend in Apeldoorn, Netherlands

Unfaired Men's hour record now stands at 52.074km (32.35mph) !

Women's hour record now stands at 46.34kph (28.8mph)!

One Hour Record Progression
The recumbent men's hour record his quickly making up ground on the UCI record since the inception of the WRRA as illustrated in this graph.

New for 2010:

Trike records are now being recognized!

Trike Recumbent definition: Same as Unfaired Recumbent, except vehicles in this class must have 3 or more weight bearing wheels, and two of those wheels wheels must have a minimum track width of 250mm.

The WRRA committee feels that the inclusion of trike records will spur technological development in this design type which will have an influential effect on commercially available trikes and velomobile design as well as open up opportunities for athletes who prefer this type of vehicle.

New rules modification on brakes:

For record attempts, Fixed gearing is the minimum level of braking system allowed. Brakes are not required for single rider velodrome record attempts, but they may be a requirement of the race organizer or an event rule. 

Helmet rules clarification:

List of acceptable bicycle helmets for WRRA records

(ASTM) F1447-97a, and F-1446-97
ANSI Z 90.4
BS EN 1078
Australian and New Zealand standard AS/NZS 2063: 1996
Canada CAN-CSA-D113.2-M CYCLING HELMETS
CPSC
CEN European Standard EN1078,
Japanese Industrial Standard  JIS T 8134-1982
Snell B-95 and B-90
Swedish Board for Consumer Policies KOVFS 1985:6
Casco Warp 2 and Warp III carbon while not stickered meets the EN 1078 specification.

Event Records Compilation being assembled:

We are now looking to review performances set on recumbents that fall into WRRA classes. These records would include RAAM, Paris Brest Paris, Sebring 12 and 24 hour, Cape Argus Tour, etc. Performances that do not qualify to standard categories of the WRRA would also be listed, such as those set at high altitude, where verifiable measurement data does not exist or in distances not currently recognized by the WRRA.

Did you know?

Straight line records are accepted by the WRRA for 200M and Kilo distances.

Separate Records will be kept for Straight line and Velodrome courses for 200M flying start and 1 kilometer standing start categories. Straight line records must exceed any existing velodrome records to be granted. (Wind and course slope must meet requirements)
