Also Tim made a good point as usual. Headset would be a good replacement. I am happy to sell you my Cane Creek 40 for the cost of nice 4-6 pack of beer and a little shipping. It should be a fine replacement for the Mindset which I believe they were using at that point. Mine old one got crushed so I replaced it with this and then proceeded to not put a ton of miles on the bike and then the BB cracked and hence why I don't need the headset. I can also sell you the fork if you are interested which would get you closer.

However again as Tim said you could be replacing quite a bit and it could become a little more expensive but overall I was happy with my Langster and can't wait to finish up the new one so I wouldn't say don't do it but be cautious if you aren't looking to spend a lot.
