I'm a lightweight but I do better in crits, just wanted to see what other people had to say about the strengths and weaknesses of both of the bikes. Any ideas on it?
All been said before, but SL4 is a climbers bike that goes up superbly, also descends on rails and very good at tapping out tempo / cadence on a ride. It is in my opinion one of the best bang for buck bikes out there as it does everything very well. However, if it is pitched in anyway, it is a GT bike that makes climbing easier. I have an SL3 and the one thing I always note post ride is that it is simply easy to ride - effortless I suppose.
The Venge is a bike for the bigger rider in the sense someone who might push 53 - 11 or 12, riders who like to ride out front, break away and ride full gas, keeping the hammer down. It is better on the flat than the Tarmac, but the Tarmac smokes it in the hills, though it still climbs well. Would suggest that the bike rides akin to a Cervelo S2 / S3 in the way it delivers power to the BB.
I suspect you could ride and enjoy either bike, but more so look at your local terrain and work out which bikes suit you. Maybe both do ?
Oddly enough, I have a Venge due at the end of the month I will be writing a full report on it but thats likely not until Spring, weather pending.
Anyway, hope this helps. As I said, nothing new in what I have written here, but glad to write it.
