Dia Compe IB-1 Integrated Headset

Durable sealed bearing headset using the most popular standard for Integrated headsets in BMX at the moment.*Note: Not all threadless headsets are the same! Diatech/Dia Compe is one of the very few companies authorised to use the Dia Compe USA/Cane Creek patented "split compression ring"Whilst this may appear a minor item... it actually has quite a significant effect in use. The split in the compression ring actually allows the ring to "grab" the fork steerer as the ring is compressed by the headset bearing adjustments. The "grabbing" prevents any possibility of "knocking" from play between the fork and the headset. Many other so called Ahead type headsets do not have this patented feature... even though, at first glance they appear to offer much the same performance. IMPORTANT NOTE: There are 3 main standards currently in use for Integrated headsets; They are all similar but NOT cross compatible... therefore check carefully which system your frame is made to accept.
