Interbike 2009 – Easton’s New 2010 TT, Road and MTB Wheels
INTERBIKE 2009 – Easton’s new EC 90 TT deep dish carbon wheelset, EC 90 carbon clincher, and Haven Disk mountain bike wheels.
EC 90 TT (above).Ã‚Â Easton increased the side walls from 56mm to 90mm for the new EC 90 TT. The Easton narrow-flange R4TT front hub,Ã‚Â which reduces frontal spoke area by 50%, is the same. The new EC90TT displays lower drag than the Zipp 808 at 0, 5, 10, 15 and 20 degree yaw angles (comparison provided by Easton).
The set weights 1424g, 30 grams lighter than the Zipp 808, and is still 9mm deeper in rim profile. Thanks to EastonÃ¢â‚¬â„¢s Variable Nipple Bed (VNBTM) Technology. This process of internally tapering the rim bed eliminates excess carbon between spoke holes and allows for a sharper inner edge. Less weight, improved aerodynamics with no loss in strength.
- MSRP:$1900 and come with SwissStop pads
EC 90 carbon clincher, and Haven Disk below…
2010 EC 90 SL Carbon Clincher
The 2010 EC 90 SL is Easton’s 1st carbon clincher. To combat over heating they are using a proprietary ThermaTecTM brake track treatment. The treatment is also supposed to help provide a smooth consistent braking and eliminate the pulsing, grabby feel found in other carbon wheels.
The entire rim including sidewalls is molded into their final shape, which means no post-mold machining that would weaken the structure.
- WEIGHT:Ã‚Â 1460 g, no rider weight limit
- HUBS:Ã‚Â 18h R4SL front, 24h R4SL rear; Custom Grade 3 ceramic bearings
- RIM:Ã‚Â Easton 38mm carbon clincher
- SPOKES:Ã‚Â SapimTM bladed black

2010 HAVEN DISK
The Haven disk has anÃ‚Â internal rim width of 21mm and weighs in at 1650 grams. And the UST-compatible rim requires no rim strip, eliminating more weight. HavenÃ¢â‚¬â„¢s unique Threaded Eyelet System employs an alloy nipple thatÃ¢â‚¬â„¢s threaded both internally and externally. The wheel uses standard straight-pull spokes and can be trued like a standard wheel.
The Haven hub is optimized for 15mm thru axles, but also compatible with standard 9mm quick release mounting via included adapter. Haven wheels are UST ready. Haven is also available in 26Ã¢â‚¬Â or 29Ã¢â‚¬Â.
