What’s special about KRU Hubs?

One of the key technological advancements we have introduced is the KRU wheel hub. In fact, there aren’t many companies nowadays doing innovation on the hubs. In practice, many wheels on the market today are little more than a selection of existing products put together and a sticker applied.

Our approach for making high quality carbon wheels has been radically different. We’ve literally designed our products from the ground up, including the hubs.

KRU Hub mounted on a wheel

KRU hubs, entirely engineered by KRU, offer performance comparable to hubs with ceramic bearings while on the other hand maintaining exceptional durability at an affordable price point.

The technology is supported by Enhanced Bearings Performance, a patented revolutionary hub design & assembly, and Self Adjusting Spokes, a clever design which allows spokes to perfectly align from the hub flange to the rim.

Enhanced Bearings Performance (EBP)

Enhanced Bearings Performance EBP Technology KRU

Enhanced Bearings Performance is a completely reingeneered hub design & assembly. Main benefits include:

  • Hubs unaffected by over-tightening of the quick release, actually rolls faster
  • No maintenance required for 200.000 km
  • Low friction and rolling resistance

Self Adjusting Spokes (SAS)

Self Adjusting Spokes – SAS Technology

The Self Adjusting Spokes technology allows spokes to perfectly align from the hub flange to the rim to obtain the following benefits:

  • The wheel supports higher tension
  • Higher wheel performance in terms of stiffness and stability
  • Greater durability of the spokes

Personalisation

KRU hubs can be personalised with hub caps available in many colours

 

About Self Adjusting Spokes (SAS)

Spokes failure is the most common maintenance issues affecting road cycling wheels for many cyclists. Tackling this problem quickly become a priority in our effort of completely redesigning wheels. Spokes are central in making sure that the structure of a wheel maintains its rigidity. Causes of their failures include imperfect alignment, an incorrect amount of tension because of improper setup or loss during normal use.
To create the SAS technology we have drilled an hemispherical groove in the hub flange and added a ball shaped washer placed underneath the spoke head. This design allows spokes to perfectly align from the hub flange to the rim increasing their ability to withstand tension loads, maintaining the shape of the wheel at lower tension and decreasing the risk of wheel failure.

Self Adjusting Spokes – SAS Technology

Major benefits of the SAS technology include higher stiffness which maximises power transfer, higher durability, lower risk of broken spokes and an improved riding experience, especially on fast corners. Our tests have demonstrated an ability of KRU wheels to reach very extreme lean angles at corners

  • The design allows spokes to perfectly align from the hub flange to the rim supporting higher tension
  • Higher wheel performance in terms of stiffness and stability
  • Greater durability of the spokes, less maintenance required
  • Faster average speed while riding corners
  • Higher maximum corner lean angle (more than 45°)

About Enhanced Bearings Performance (EBP)

In recent years the development of cycling wheels has been predominantly focused on assembling together parts from different manufacturers or at most applying minor modifications to the shape of the rim. The industry appears to have failed to introduce meaningful technology advancements and to have completely forgotten the central component of a wheel’s structure: the hub.

Our approach has been diametrically opposite, the hub is where we’ve started the development. During our research we noticed two big areas for improvement over existing products on the market. One is an imperfect alignment of the bearings which often causes durability issues, especially when the quick release skewer is tightened excessively. The other, is that the vast majority of cyclists never apply any maintenance to the wheel, even less to the hub. This means that there is a substantial amount of cyclists whose wheels and hubs are literally slowing them down.

To address these issues we have completely redesigned the structure of a wheel hub and patented it under the name of Enhanced Bearings Performance (EBP). The KRU hub assembly process is also unique in the industry. We use a full 5 axis CNC machined production process in a single manufacturing station while bearings are all inserted at once with optimal alignment and controlled preload.

Enhanced Bearings Performance EBP Technology KRU

EBP brings numerous benefits. Firstly, our hubs provide minimum friction and rolling resistance. The performance is comparable to those with ceramic bearings with the distinctive difference that we are able to guarantee exceptional durability and much better value at a lower price point. In fact, KRU hubs are guaranteed to require no maintenance for 200.000 km. An additional benefit is that our product is unaffected by over-tightening of the quick release skewer. Effectively, KRU hubs make you go faster and maintain their performance for much longer than any other product on the market.

  • Completely rethought hub design and assembly
  • Unaffected by overtightening of the quick release (actually rolls faster)
  • No maintenance required (200.000 km guaranteed)
  • Fast rolling resistance and lower friction – comparable to ceramic bearings
  • Performs well where other products fail

KRU Wheels are now UCI Certified

We have fantastic news for all the racers out there who compete in UCI races. UCI is the Union Cycliste Internationale and the world governing body for cycling and cycling events.

KRU Cycling has obtained the UCI certification for “non-traditional wheels” and are now added to the short list of companies having obtained this certification.

UCI equipment regulation require that wheels used in “massed start competitions” in the disciplines Road and Cyclo-Cross must be tested and have obtained a certification, unless those wheels are “traditional”. All carbon wheels are considered “non-traditional” and therefore require certification.

Additionally, this certification makes KRU Wheels  ITU (International Triathlon Union) legal.

Our models that have now obtained the certification include:

  • C-38 (Clincher)
  • C-55 (Clincher)
  • C-88 (Clincher)
  • T-38 (Tubular)
  • T-55 (Tubular)
  • T-88 (Tubular)

Only selected companies are approved to appear on the list and we are very proud to have joined the UCI certified list.

About KRU Wheels

KRU is a new brand of wheels and components founded by a group of italians, particularly a former lead engineer from Deda Elementi.

Their first products include a large range of carbon wheels, clinchers and tubulars, characterised by interesting technological innovations.

ZERO MAINTENANCE HUB
The hub, entirely engineered and designed by KRU offers performance comparable to that of ceramic hubs while also maintaining exceptional durability. It is in fact guaranteed to be maintenance free for 200,000 kilometers. Their patent “Enhanced Bearing Performance” avoids bearings compression and slower rolling of the wheel in case of excessive tightening of the quick release skewer. The wheels are also customisable with stickers and coloured caps.

MOUNTAIN-PROOF RIMS
The rims are characterised by a special material, the “Vapor Grown Carbon Fiber”. This substance, which originates from the aerospace industry, makes the compound thermally conductive so that heat generated while braking quickly dissipates on the entire surface of the wheel. Consequently, KRU Wheels reach temperatures that are 30% lower and can resist descents that are twice as long as competitors’ products. This makes KRU wheels dolomites-proof.

EXCEPTIONAL DURABILITY
To further improve the durability of their products, KRU has developed numerous technologies in order to maximize the ability of their wheels to withstand wear and use.
“SELF ADJUSTING SPOKES” is a technology that allows the perfect alignment of the spokes from the flange to the rim, making the wheels more resistant to heavy loads and limiting the risk of rupture of the spokes.
“SEAMLESS LAMINATE CONSTRUCTION” improves the lamination process of the wheel by making sure that continuous material is used as much as possible instead of applying traditional methodologies where different pieces of carbon are joined or glued together. This limits the risk of cracking and breaking and the resulting product is solid and free from weak points.
