Re:
Thanks for all the encouragement. It was a complete impulse buy, I normally have steel frames and I've never had an aluminium frame before. The only mountain bike I have is a 91 Kona Lava Dome so its going to be interesting to see how this feels. I will be trying the stock rigid fork as changing the fork to an On-One carbon will mean I'll have to change the headset.
I hadn't a clue what I was buying when I got the wheels, but they seem light enough. Tyres came with the wheels and I wanted to see how the bike felt, but they are a pain to mount. Going tubeless will probably be the best option.
Will treat it to some blue upgrades if I like it. I've got the option of putting gears on as it's got full cable routing for a 1x11 on it. But I'm going to keep it single speed for now.
