I’ve commented on my Whyte 19 Steel on here a few times so it’s worth a search.
Summary – I like it. I’ve fiddled with the dropouts; in the summer I can get away with them long and it makes the bike more stable for going fast, but in the mud they are better off in the middle to get more feel and help limit tyre slippage.
I ran it SS for the euro SS championships after my other bike died – worked really well and was a great bike to race.
I like the feel of steel and I prefer it to my last alloy bike, but I may have liked the Alloy… who knows… I never tried it as I couldn’t afford it.
Downside – I think the bottom bracket would be nice a little lower. The BB30 on all the steel frames I have seen have been a little tight. The seatpost on the steel is 27.2mm, and mine has become very scratched = badly finished frame? Seat tube bottle bosses limit how low you can drop the saddle.
I had a problem with my frame but Whyte were excellent to deal with so thumbs up for support.
Overall – it’s a great bike. Rides well for almost all terrain and is a great mile muncher. Drop the seatpost for the doonhalls and the slack headangle makes it ride like a little 4cross bike that tempts you into daft jumps and serious hooning into berms etc… but watch your skinny XC forks and wheels as it’s easy to get carried away.
