2004 Giant Yukon; Learning the ins and outs

I have been lurking for a while on the site and have learned a ton! So about time I make my first post.

I have a 2004 Giant Yukon that I rode a lot through college, but did very little maintenance during that time. I am now getting back into biking (commuting 14-18 miles round trip) and have been riding this bike again. I am using it as a learning experience for my mechanic skills. I am replacing the cassette, chain, and chain rings, but need some advice from some veterans. Here are the specs (https://archive.giant-bicycles.com/us...04&model=10763). And am leaning towards the SRAM PG-850 8 speed Cassette.

What would you all suggest? I am trying to keep cost down, due to the bikes value. Thanks in advance for any guidance . I also picked up Zinn and the Art of Mountain Bike Maintenance.

That would be a good choice. About all you'll get from the more expensive cassettes is a little less weight which I doubt is of concern to you on this bike. Welcome to the work of bicycle mechanics. Be warned, it can be addictive.

SRAM cassette sounds good, I've run them on many of my bikes. I also buy SRAM chains since they come with a re-useabale master link.

Are you sure the chainrings are worn out? Before you buy new ones check to make sure the ones you have are removable. On the cheaper cranksets the rings are riveted on. Also, it might be cheaper just to get a new crankset. If you want you can upgrade to a new Shimano Hollowtec crankset with an external bearing bottom bracket. Really depends how much money you want to stick into this bike.

Thanks for the input and the welcome. Pretty sure the chainrings are toast. Looking now to see if I can actually replace them, or if I will need to purchase a whole crankset.

I don't see anything wrong with what you've already chosen as a cassette - great reviews for it. You can spend a lot of time looking at alternatives or buy it and go on to the rest of the bike. I just look at reviews online for components I am considering if I don't have the experience with them. The input from a forum is fine but y9u get a much broader selection when you look at reviews on multiple sites.

This is an entry level hybrid and not worth doing much upgrading or spending a lot of money on. The suspension fork is really a low line item and indicates the overall quality level of the bike. By the time you do a lot of parts replacement, you will have spent a large fraction of the cost of a new and better bike.

I agree with replacing the cassette and chain but, from the link you referenced I believe the chainrings are riveted to the crank and can't be changed. As noted, are you sure the crank needs to be changed? Chianrings last a long time and are less effected by wear than cogs. Unless the new chain skip on them there is no reason to spend the money.

HillRider, would you suggest that I go ahead a replace the chain and cassette, (roughly $30-35 and a lot of learning ) and if it continues to skip, start looking for a new bike? I would be hard pressed to spend 200-300 on a new crankset for this bike.

I severely abused the bike and rode it with minimal (no) maintenance for years. I definitely agree with the quality level of the bike and don't want to spend much, but would like to use it if it has some life in it.

I have also been searching craigslist for something inexpensive to wrench on, and enjoy.

If the chainrings are indeed badly worn to the point the new chain skips on them too the crank does need to be replaced but, what I was cautioning you about, was spending much more than the bike is worth. A Hollowtech II crank and bottom bracket as FastJake suggested would be a good upgrade but more money than the bike is worth investing. You could get an Acera or similar crank at low cost and that would be worthwhile.

As HR says, you can get a nice new Shimano crankset for $35-45 for a square taper BB. If you've got a non-square taper BB, you should still be able to get a replacement crankset for $40 or so, assuming the likely suspects.

waking a old thread...
I have been trying to repair a 2003 giant yukon as a project.
I have put on a new rear cassette, chain, new bottom bracket, rear derailleur cables, etc. The part I am stuck at is the replacement crank when bolted to bottom bracket binds. Here are pics of the old and new cranks.
On the black crank there are 4 tabs that are not present on the other crank. The old crank was a sr suntour?
The replacement is a Shimano Tourney TY501 6/7/8-Speed 175mm 24/34/42t Square Crankset

Binds where?
Likely your new crank requires a longer length BB if the chain ring is rubbing.

Bikes: Too many. Cannondale SuperSix, Trek Remedy 8, Trek Crossrip+ get the most ride time.

Any price level Shimano, SRAM, Sunrace, or Microshift cassette will shift fine. The differences relate mostly to weight TBH.
