Tarmac SL7 Compatible Parts & FAQ
Compatible Parts
Disc brakes only
The Tarmac SL7 is compatible only with disc brakes.
Forks
Using Rider First Engineering, there are three fork variations used on the Tarmac SL7. These forks vary in geometry and stiffness to ensure ride quality and performance is maintained for all frame sizes:
| Frame Size | 44cm | 49cm | 52cm | 54cm | 56cm | 58cm | 61cm |
|---|---|---|---|---|---|---|---|
Fork | V1 Fork | V2 Fork | V3 Fork | ||||
| Fork Offset | 47mm | 44mm | 44mm | ||||
Seatposts
The seatpost for the Tarmac SL7 is a custom aero-shaped post. A round seatpost is not compatible. There are 2 setbacks: 0mm and 20mm. There are also 2 lengths: 300mm and 380mm. These seatposts use the Specialized Pave seatpost clamp hardware for either 7x7mm or 7x9mm saddle rails, 2812-9050.
Drivetrain
Max front chainring: 1x 52t, 2x 55t
Bottom Bracket
Tarmac SL7 models use a threaded BSA 68mm bottom bracket.
Cable Routing
Cable routing for the Tarmac SL7 frame is fully internal.
For models equipped with AeroFly bars, a piece of foam churro is included in the small parts box. This churro is intended to be cut into small lengths and used in the bars to reduce noise.
Cables are routed beneath the stem using a cable bat, S204800003. Cables are routed into the upper stem transition and through spacers into the top cap and compression ring.
ICR grommets are used for both the chainstay and fork brake house exits, S179900013.
ICR ports are available to accommodate many variations of electronic and mechanical shifting:
Drivetrain | Front Derailleur | Rear Derailleur |
|---|---|---|
| Mechanical, full length housing | S169900008 | S159900006 |
| Mechanical, exposed FD cable | S206500007 | S159900006 |
SRAM eTap | S179900015 | S179900015 |
| Shimano Di2 | S179900015, route wire behind FD hanger | S159900006 |
| Campagnolo EPS | S159900006, route wire through port behind BB | S159900006 |
A removable rubber BB cover gives access for routing, S189900021.
Frames may be converted from one type of drivetrain to another with service parts available from your Authorized Specialized Retailer.
Tire Clearance
Tarmac SL7 has clearance for 700x28c tires on Roval 21mm wide rims. Tires up to 700x32c may fit with less than 6mm of clearance. As tires and rim width vary in size, ensure that you have adequate clearance around the frame, fork and tires before riding.
FAQ
Q: What has changed between the SL6 and SL7?
A: The SL7 frame is more aerodynamic than the SL6 without adding any weight or sacrificing stiffness. As a complete bike, the SL7 features a more aerodynamic handlebar, stem, and Roval Rapide CLX wheels.
Q: What is the difference between the S-Works, Pro, and Expert versions?
A: The S-Works frame is built with FACT 12r carbon for the lightest and stiffest frame possible. The SL7 frame for the Pro and Expert bikes has the same aerodynamics but uses FACT 10r carbon. Pro bike builds have higher end components than Expert bike builds to provide options at different price points.
Q: Are there other models of Tarmac still available?
A: Yes. The line doesn’t stop with the Tarmac SL7 Expert model.
