Hello everyone,

the last couple of months i was thinking to convert my Mongoose Crossway 450 from 2006 http://images.buzzillions.com/images...171684_raw.jpg into a single speed. i just need advice on if it's worth it, or if i shall look for better options?

i'm driving this bike for quite some time now (since 3 years actually) and i've had frequent problems with the shifting and the brakes. the front and back derailer were always displacing themselves, as did the brakes. i think the shifting will break soon anyways. some of the parts are really worn out, and so far i din't think it was worth replacing them.

I've been a courier ever since i got the bike. it offered a nice experience for novices. but over time i got better and more conditioned and as it is now, it just doesnt cut it anymore. it's way too hard to drive fast with it over a longer period of time. i'm also fed up repairing the shifting and brakes so often.

So my question is: is it worth it to get rid of everything except the frame, or should i keep some parts like the bar and rims and tires and replace the rest? Or should i buy a new bike? or should i look out for a good frame and buy the rest one by one?

As it stands now, it weighs about 18 kg. everything made from aloy.

thanks a lot in advance.

sincerely,
phil
