Rebuild or Replace 2005 Scott Sub 20

Hello everyone I'm new to the forum. Wish I had found the forum sooner. Looks like lots of great information is available here.

I have been riding a Scott 2005 Sub 20 for the last 12 years. I love my Sub 20 and I believe it fits me very well. The bike has been used on a regular basis and I feel that the wheels and drive train are worn and need replacement. The rest of the bike is in good shape. I have always done my own bike and auto maintenance and repair so I have tools and hope to upgrade the bike myself. Kind of a winter project.

I am trying to determine if it is worth rebuilding the Sub 20 or if I am better off just taking the money and use it toward buying a new bike such as the Trek FX Sport 4 or something else that is comparable to the Sub 20. I have never done major repair work on a bicycle so I do not know how difficult it may be to obtain and replace the wheelset and drivetrain. Are these items difficult to replace on your own? Paying someone to replace them would probably increase the cost quite a bit and I may be better off buying a new bike. Thanks in advance for your thoughts/suggestions.

Which items need replacement?

I take it it's first and foremost the drivetrain; chain, casette and chainrings are consumables and need replacing regularly. Probably the bottom bracket too. Not very difficult when having the right tools (there are some specific ones you'd need). There are many instructional videos on youtube, should be doable if you are reasonably mechanically savvy. Cost wise it depends largely on the component quality; going for about the same (Alivio level) shouldn't be too expensive. Also all the cables and housings as well as brake pads probably need replacing too, but those generally are cheap parts.

Regarding wheels - hard to tell without seeing. Tires are consumables too, and are easily replaced and don't generally cost much. It looks like you have rim brakes; it is possible the rims (braking surfaces) are worn and need replacing. Hub bearings can probably be repacked. But if both hubs and rims are shot, you're looking at new wheels; decent wheels can set you back a sunstantial sum of money.

Bottom line: if you love the bike and fits you very well, repair it. Especially if you don't need to replace the wheels. You might want to take it to a shop and let them evaluate what needs to be done; then you'd know the ballpark figure for the repair and can decide based on that.

Thanks! I think I will have my local bike shop look at it. I got this bike slightly used so did not pay much for it. It has been ridden by me regularly for the last 12 years. The only maintenance done to the bike has been cleaning and brake pad replacement. I'm starting to think that repair is not worth it and a new bike is in order. I like the bike and am thinking I could probably get another year or two use out of it with only minor work. But then again this may be a good time to buy with end of season deals.

Yes the bike has rim brakes and I would think after more than 12 years of use the rim/wheels are probably due to be replaced.
