FAQ - HED Cycling Products


What PSI do I put in my tires?
Probably less than you think. Tires on Plus rims have more air volume than they would on narrower rims. For road size tires the volume is about 25% higher on plus than on an old 19mm external rim and 10% higher than on a 23mm external width rim. Increased volume means you can and should run less psi than on a narrower rim. The rolling resistance will not increase, but comfort and tire grip will both go up. Consult our PSI chart for Hed’s recommendations. https://store.hedcycling.com/tire-pressure/

What bearings are in my hub?
Five pawl 525 hubs and three pawl hubs dating back to 2013 use 6902 bearings. Three pawl hubs dating 2010-2012 use 1526 in the hub shell and 6902 in the cassette body. Numbers are on the rubber seal of the bearing, you can always look at the bearing itself.

Front disc brake hubs use 6902. Current front rim brake hubs with radial lacing use 6900. 2015 and older front radial hubs use 6901. Again, the bearing itself can always be checked to confirm the bearing number.

Can my wheel be converted to Shimano 11sp?
If your hub matches one of the five shown on this page https://store.hedcycling.com/11-speed-conversion/ then it can be converted. This covers the time period from roughly 2012-2015.

Can my wheel be converted to XD/XDr?
Hed 545 hubs are convertible. They were used from 2016-present. The cassette body has 5 pawls. Older 3 pawl system hubs are not convertible. This includes the hubs pictured here https://store.hedcycling.com/11-speed-conversion/ as well as all earlier versions.

Can my wheels be set up tubeless?
ONLY if they are Plus models. Older 23mm wide C2 models are NOT safe to use with tubeless.

How do I convert my hub to 15mm or 12mm thru axle or QR?
545 disc hubsets can be configured for 100mm x QR/12mm/15mm on the front hub and 135 xQR/142 x 12mm on rear hubs. Parts are available here: https://store.hedcycling.com/road-disc-brake-axle-kits/. Conversion parts for GP models are here for QR: https://store.hedcycling.com/gp-disc-brake-skewer-kit/

If you mix up the parts or lose them, your wheel will not work anymore. If it is not clear how to do the conversion, take your wheel to a shop.

What is the maximum spoke tension for my wheel?
For road and gravel wheels, max tension is 130 kgf on the rear drive side. Rear ND side should have even tension. We do not specify a ND tension because that side is completely dependent on the correct drive side tension – it cannot be adjusted independently. Front rim brake spoke tension should be 110 kgf. Front disc brake brake side tension should be 120 kgf.

For Fat wheels tension should be 95kgf.

What is the recommended tubeless valve?
An extender with a metal flange and rubber grommet on the rim end should be used. Valves with only a conical rubber grommet on the rim end are not recommended.

What tires/size do you recommend?
28mm actual width for Ardennes and Vanquish road use. For Jet wheels 25mm actual width is the fastest option, but only by a factor of about 3-4 seconds over 40km. Unless a podium step hangs in the balance, 28mm for Jets wheels is a very solid choice. The difference in speed will only work out to approximately .05kph per hour between 25 width and 28 width. Note that we are recommending ACTUAL MEASURED width, not labeled width.

Will your wheel fit in my bike?

Tires are your concern. Older frames (5 -10 years ago, depending on the maker) don’t have the tire clearance common in more modern frames. If you are unsure about fit, measure your tire width with calipers – so that you have a starting point. Then gauge the clearance that you have with your existing set up. Use a set of allen keys as feeler gauges. Check clearance at the chainstays, fork crown, and rear brake bridge. When you find that one wrench fits and the next size up doesn’t, then you have your clearance number for the existing set up. On Plus wheels, most tires will measure 2-4mm wider than the labeled size, and they’ll be about 2-3 mm taller than the same tire on a narrower rim. You should have 3mm clearance minimum.

What spokes do I need for my wheel?
Please consult the Tech Manual

What the difference between a Belgium and an Ardennes?
Ardennes are Hed’s complete wheel set that we hand build here in house. There are different Ardennes models with hub, rim extrusion, and spoke differences. Ardennes wheels are all 25mm external, 21mm internal widths. There are no options for customizing the different models. Belgium rims are just the Hed rim that will be built into a custom wheel set by your local builder. Belgium rims come in one extrusion, the same as the rim brake model used for Ardennes. Hole counts are 24, 28, and 32.

Do your tubeless rims need tubeless tape?
Yes, it is supplied with the wheels. Use 2 layers of the supplied ivory colored tape or one of supplied black tape.
