Does Specialized's higher grade of Aluminium(i.e. E5 or M4) provide a better ride?
Where Specialized uses their higher grade of aluminium, it is also on a bike that has better specs than its A1 brethren, so excitement about the better spec'd bike could be influencing an overall more favourable view on the bike's ride quality.
For people who have ridden both an A1 and E5 framed Sirrus or an A1 and M4 framed Crosstrail, did you find there was any difference in ride quality from the different grade of aluminium used and if so, which grade of aluminium gave the better ride or could you not tell a difference?
*Inspiration for this thread came from a poster on these forums who has had both an A1 and M4 framed Crosstrail and he had the inkling that the A1 framed Crosstrail provided a slightly better ride.
