Pros: - Lightweight
- Adjustable reach
- Extra material milled out to reduce weight
- Graphics look great
Cons: - Cost
- Bars tend to slip
Recommendation: A top of the line stem that is plenty stiff and durable. It is extremely light but its strength is not compromised.
The bar clamping area isn't quite up to snuff and my bars slipped a couple of times. To remedy this I used the same grip type paste that guys are using in their carbon fibre bikes to increase torque grip.
Unfortauntely the F1 will cost you a small fortune. Its not for everyone but it will bring up your bling factor. It looks great.
