2015 7-series preview
The 725 and 735 frames have become iconic to the Leader name, starting out with the goal of creating a light weight and aero dynamic frame for the velodrome, and slowly evolving into a frame durable enough for a street commute. With those two schools of thinking in mind we hit the drawing board on how to enhance these already top of the line track frames, here’s what we came up with.
TAPERED HEADTUBE
For those of you on the track or racing competitively with their 725/735 we’ve added a tapered head tube. With a design which is larger at the bottom than it is at the top, the rider will notice three main benefits: BETTER FORKS The wider bottom portion of the head tube allows for stiffer and stronger fork crowns. Our I805 and I806 forks have been redesigned to capitalize on this benefit SMOOTHER RIDE The larger bearing of the headset used for a tapered head tube handles impacts and dissipates bumps in the road more efficiently then a standard pipe style head tube. LESS FLEX The 725 and 735 are known for their large aero downtubes. Our new tapered head tube takes advantage of their oversized tubesets, by increasing stiffness as the area where the two meet is much larger. NOTE: The I805 and I806 forks for 2015 feature tapered steer tubes to take advantage of these new benefits. These 2015 forks are designed to only work with tapered head tubes. Please note however our I803 carbon fork will work with all past Leader 725/735 models featuring the standard pipe style head tube. LG/2015

INTEGRATED SEATPOST CLAMP New for our 2015 725 and 735 is an aggressive looking integrated seatpost clamp posting a few key features setting it ahead of the competition: CAN’T BE STRIPPED The most known problem with integrated seatpost clamps is their ability to be stripped if the rider over-tightens the securing bolt, thus ruining their frame. With Leader’s new design, this seatpost clamp cannot strip as it does not thread into the frame but rather a locking nut on the opposite side of the bolt. Therefore in the unlikely situation the bolt is overtightened, a replaceable locking nut is the only part of the bike that will be damaged. NO SLIPPAGE Common seatpost clamps are only secured with a single bolt. In some cases, this bolt might not be enough on it’s own to prevent the seatpost from gradually slipping during riding, no matter how much it is tightened. Leader’s new design features dual securing bolts, ensuring the seatpost is held firmly at the desired height. SOLID CONSTRUCTION With the newly designed integrated seatpost clamp the 725 and 735 frames feature a solid seat tube-to-seatpost construction. This eliminates any weak points in the seat clamp area, ensuring a safe ride and a long lasting frame.
