If you want to make your front end lighter. I would look at some new forks echo lites are a good choice and a good price at £70, or if you are prepared to spend a bit more they are zoo forks £90 GU forks £105 and the echo team forks at £105 which are very good quality. Maybe look at some new bars,such as the echo tough bar, or the GU flat bar both £30 which is a good price and are very light and good quality. A new stem (echo zoo try all) are all good or maybe a Monty ti but they are a bit pricey, the stem will not make it a lot lighter, but it will make a massive difference to how the bike rides. Maybe if you have a bit off money left, i would put it to a new rim, they are all mainly about the same weight its just which one you like best couler style etc. Toby
