Q. Are WattShop products compatible with my bike?
Head to our Technical Resources page and check out our compatibility guide to determine whether or not your bike is compatible with our products. If you can’t see your bike in the guide, please get in touch at the address listed above.
Q. My bike isn't compatible with the Anemoi Extension System, can anything be done?
Customisation options are always an option. Please get in touch if you would like to know more.
Q. How do I know which parts I require for the Anemoi Extension System?
Download our dimension guide and input your dimensions into our geometry tool. The outcomes of the tool will determine the components needed for your specific set up and relevant fit information.
Q. Is the Anemoi Extension System compatible with the Trek Speed Concept (2023)?
For the Trek SC, you will need to modify the riser stack spacers to ensure compatibility. The Trek riser stack spacers have two interlocking pins to the front of the riser and a raised boss around the rear bolt hole. These aspects need to be removed with either a dremel or a file. This will then offer up a flat top riser stack which is required for compatibility.
Q. What information do I need to provide for the arm rest drilling service?Please let us know dimensions A, B, C and D from the drilling guide. This will allow us to drill the holes to suit your specific position and mounting requirements. If you require a hole grid please let us know as this can be done based on these dimensions.
Q. How long will my waxed chain last?
Typically, around 250-400km of dry open road use. This will be noticeably longer on the track, and shorter in the rain or in extreme temperatures (+40 °C). After this period, you can send your chain back to us to be re-waxed.
Q. Do you post outside of the UK?
Yes, we will happily ship anywhere in the world. Worldwide shipping options should be available in your cart but if you don't see an option that suits please contact us for a postage quote.
Q. How does Watts saved convert to time trial speed?
As a general rule, for every 1 Watt in aerodynamic drag you will save 0.1 seconds every kilometre. E.g. you’ve come to a WattShop aero test session and we have reduced your aerodynamic drag (CdA) by 10 watts. Assuming you hold the position, you can expect to go 16.1 seconds faster in a 10mile TT and 40.2 seconds faster in a 25mile TT.
Q. What do I need to bring to an aerotest?
Our Performance Engineer will be in touch before your test to discuss your aims and objectives for the session. They will let you know about any specific items that should be brought along. Please bring all the spacers/bolts for your bars, and your bike set up in full race mode including everything you normally race in be it race wheels, skinsuit, overshoes / calf guards, gloves etc.
We stock a range of equipment for testing, including 22.2mm extensions, a range of stems, various hydration systems, several helmets, and several skinsuits/overshoes. If you want to test something specific please mention it in your call and bring it with you.
Finally, if there is something specific you might want to test but don’t have, let us know and we’ll try and source one for your test.
Q. I’ve never ridden the track before, is that a problem?
No, it’s not a problem and most riders take to the track very quickly. At the beginning of the session you will have the opportunity to warmup and acclimatise yourself to the velodrome. Within a few laps it will become second nature.
Q. I don’t have a power meter, can I still come for an aero test?
This is not a problem, we have 2 rear wheels fitted with Powertap hubs (10/11 speed) for clients to use in aero tests. If it is a track bike you wish to be tested on and you don’t have a powermeter, please contact us and we can find a solution.
Q. My PB for a 10mile TT is only 23 minutes, is it still worth coming for an aero test?
Yes, it’s absolutely worth coming! If you are going along at 60kph or 40kph you will still be using the majority of your power to overcome aerodynamic drag. For example, if you have a 10mile TT PB of 23 minutes (26mph average), at that speed over 85% of your power is used to overcome aerodynamic drag.
Aero testing isn’t only for professionals or those fighting for the win. We have extensive experience testing a range of riders, from those looking to dip under 24 minutes for a 10-mile TT, all the way up to multiple Olympic champions. A reduction in aerodynamic drag will make you go faster no matter what speed you’re going at! So, don’t be shy, tell us your goals and we can help you achieve them!
Q. How does the booking process work?
If you wish to book an aero test session, please email firstname.lastname@example.org At this point you will be given the latest track availability, as well as the invoice for your aero test. As soon as you have paid the invoice, we will contact the velodrome to book your track time. Once we have received confirmation that the session is secured, we can start planning your aero test!
Q. I want to test helmets. Do I need to bring them with me?
We stock a range of helmets for clients to use during aero sessions. If you have a specific helmet you wish to test, please let us know and we will try and source one!
Q. I can’t change the extensions on my bike, is that okay?
During the test, we will always follow the data, as such we may need to change the extensions. If you are unable to fit standard 22.2mm extensions please contact us and we can find a solution before the test.
