The Thunderbolt is the new and improved descendent of the Twombolt. It is still one of the most technically advanced crank designs on the market. Due to continued advancements in our legendary 41-Thermal® processing and heat-treatment system, fatigue life has been increased by a massive margin.
Our Socket Drive™ interface system has been in use on our Flatware cranks since their inception, and it was only a matter of time before the system was adapted into our Thunderbolt cranks. The time has come.
In a nutshell, the Socket Drive™ system is a 9 sided interface which eliminates the need for a sprocket bolt. The sprocket itself is machined so there is no need for a sprocket insert of any kind. The two work great together.

Please note, these cranks will not work without a corresponding Socket Drive™ sprocket. We offer the Killington, La Guardia, and Tom Dugan Fang sprockets in Socket Drive™, and certain boutique brands already offer Socket Drive™ compatible options.
Packages are generally dispatched within 24 hours after receipt of payment has been received. Smaller items are sent via a postal service whereas larger items such as complete bikes, frames and bars are shipped via our courier service.
Delivery costs are additional to the displayed price and vary depending on the country of delivery and the quantity/weight of goods ordered.

To avoid this place all your orders together.
