The TiiTAN Block

Tiitan block rigged with rope

Introducing the TiiTAN Block, the latest high-performance sailing pulley from Allen. The TiiTAN is a further development of the industry-leading XHL block range and is charting new territory for the small pulley market.

Titan – A thing of very great strength” – Oxford dictionary definition.

Weighing in at only 28 grams makes the TiiTAN the lightest and strongest 30mm ball bearing pulley available on the market. This is an incredible 30% weight reduction when compared to the 30mm XHL block.

The new lightweight Titanium sheave includes our specially devised V profile, optimised for the fast running of rope without weakening the working load of the line. The V profile additionally allows smaller Dyneema or wire lines to be paired with the TiiTAN block, whilst retaining the friction reduction benefits of a larger sheave diameter.

The TiiTAN bearing system is one of a kind. Featuring twin rows of ceramic ball bearings running on a stainless-steel axle gives the titanium sheave unmatched rolling speeds. Ceramic ball bearings also offer the added benefit of reduced friction in salt water, when compared to stainless steel bearings.

A key feature within the TiiTAN bearing system is the use of a precision plain bearing washer. When the TiiTAN is exposed to extreme static loads, which would normally cause damage to the internal bearing system, it changes to a plain bearing block. Stopping the ball bearings from getting damaged and thus no longer performing as designed. As soon as the static load is reduced the TiiTAN returns to a high-performing dynamic block.

The load at which this change happens has undergone meticulous testing and development to ensure the block stays in dynamic mode for as long as possible.

Aluminium side cheeks hold the TiiTAN together and offer a much stronger and longer-lasting body that holds its shape under extreme loads. These side cheeks feature a chamfered rope guide to keep the block in the correct orientation as well as two lashing line holes. We recommend using thin whipping twine or kite line to lash the attachment rope in place.  

The TiiTAN block is perfect for use across a wide range of watercraft, including high-performance dinghies, foiling dinghies, sports boats and grand prix yachts. Applications can range from vang cascades, halyard turning points, backstay systems, highly loaded Cunningham, and outhaul systems.

ILCA TiiTAN

ILCA sailors will be happy to know the new TiiTAN block is also available in a specifically designed ILCA vang block version.

Featuring a slightly longer body to incorporate the ILCA vang key into a neat, lightweight and extremely strong package. The vang key is held in place with a clevis pin and split ring, so is easily replaced.

The ILCA TiiTAN block is currently available in a stealth grey colour for a limited time.
