Armrest Stack Height Spacers are designed to increase the stack height of the armrests only on a non-integrated Time Trial / Triathlon aero bar position. The raised stack height produced, fine tunes your set-up to provide improved comfort in the aero position.
 
Simple, but effective. Durable and reliable.
 
Optimising the armrest stack height is proven to increase comfort and be more sustainable, so can be faster and well suited for all distances of riding from the 1 kilometer 'kilo' time trial and track pursuits, all the way up to a full Ironman triathlon bike leg.
 
These stack height spacers come as standard in a set, with one pair of 5 mm, 10 mm and 20 mm stackers. Custom height stackers also available upon request. Priced for one custom height pair.
 
Armrest Stack Height Spacers use a universal fit pattern, which will work with M4, M5, M6 mounting with front-rear screw orientation.
 
Durable plastic contruction which has been thoroughly tested since 2018 and over-engineered to avoid the issues seen on plastic products from other brands. Aluminium or Carbon Fibre is not necessary for this load case. Prototype versions of these wedges have been ridden to top 10 placings in Cycling Time Trials National 10 and 25 mile Time Trial Championships.
 
Come supplied with M5 countersunk screws in lengths to suit the most common Time Trial / Triathlon bike aero extension set-up.
 
Designed to work perfectly in conjunction with the Ward Armrest Wedges and aluminium alloy Ward High Side Ergonomic Armrests.
 
Note: These are not intended for use in spacer stack to raise the height of aerobar extension poles and are not suitable for this. Stack the armrest height only!
