to be perfectly honest i think your best option would be to scrap that monty and try to buy a full bike off here, you'll probably find that you can buy a top notch second hand trials bike for around £500-£600 when it would have cost over £1000 to build brand new. Also if you continue to build up that monty chances are you will have to spend alot for parts like wheels i.e. profile hub mucho expensivo also imo vee brakes really arent up to the job so id recommend magura HS33's
