Upgrading a ~2001 Trek 820

Hi to all,
I'm trying to line up a ton of XC/singletrack riding for this summer, and my bike is a stock Trek 820 from ~2001. You know the deal--crappy plastic pedals, heavy steel frame (I love the frame), etc. I'm budgeting about 250 bucks to upgrade it. I'm fully aware that much better bikes exist in the 500 dollar range stock, but replacing this bike is, for the time being, out of the question. In short, it was a gift that I'm welcome to upgrade, but would be loath to cast aside. I've already come across some pedals I like (Shimano m324) and am going to pick some up from a friend, and have roughly 200 bucks to spend from here on out. My first priority is to get some better brakes on there--would it be logical/feasible to put some Avid bb7s on there? Knowing absolutely nothing about the disc brake market beyond that I don't want fluid-driven brakes, I get the impression that the bb7 is about the best ball-bearing disc brake one can get...Feel free to insert correction/laughing as necessary. Quite simply, I'm a total newbie at this, and simply want to get my beloved frame into better usable condition for some xc/singletrack use around Western Washington this summer. Thanks in advance for any help!

You're not going to be able to do disc brakes, the 820 of today still doesn't have disc brake tabs. For brakes, I'd probably look into shimano lx or xt v-brakes and use what's left to get a set of clipless compatible shoes.

Well, crud. Thanks for the heads up on the impossibility on the disc brakes, anyways. Darn. I'd just gotten done talking myself into paying for them, too. Am I going to see a significant difference going from the stock no-names to the shimano lx/xt v? Thanks again for helping me out, I really appreciate it!

You will notice a considerable difference upgrading to the Lx/xt v's.

At the risk of investigating an upgrade I might not appreciate, I hear a lot of people complain about the front fork on the 820--I know the options are limited for a new front fork due to the steering tube size, but what would a new fork do, and anything specific to look for? I've read the FAQ, I'm just trying to get a feel for if it would be worth the money. As always, much appreciation for your insight!

Edit: on further reflection, I'll leave the fork alone until I know better. I'm oogling some Shimano XT M770 V-brakes...at 50/ea that's a tolerable price...That plus the m324 pedals and a decent set of shoes should get me started...maybe some new rubber too, but good enough for the time being, methinks. Thanks for the help!

Is it an RST Cappa? If so, please remove it. You have no steering tube size issues. Not on a 2001 Trek 820. The top two places to spend coin on that bike are the brakes and the fork. A better fork won't bob around so much, will most likely give you a little more travel and some real adjustment options. A Judy, er.. Dart can be found online that won't kill all of your budget and will be better than the RST. Keep the low end drive train adjusted and watch your cables. I bought my friends 01 820 several years back when he desperately needed some cash. He rode the hell out of that bike and sometimes I take it out for grins. Usually I keep it for him to ride. The dumb ******* never bothered to replace the bike. It currently is stock save for the stem/handle bar, fork ( a Manitou Black I had laying around doing nothing) and XT brakes. Also better cables and housing. Enjoy your ride.

Here's what you can do:

1 - get a cheap set of Shimano SPD clipless. I got a used set of XTs that were 1 year old for about 25 dollars plus shipping off ebay. GREAT deal - or go and get a nashbar branded one since they work fine (seriously people overhype the necessity of high end components)

2 - if you NEED disks (which I often do) you can get a new fork that is disk compatible off nashbar for like 55 dollars plus shipping http://www.nashbar.com/profile.cfm?c...%20ATB%20Forks
Wait till it goes on sale and you'll be gold.

3 - get Avid BB5s (not BB7s, they're designed for road and as some people responded in a recent thread about them, they might not be fit for mtbing in terms of stopping power and mud shedding design). Make sure to only buy a front caliper and rotor as that is all you'll be able to do.

4 - install or have a mechanic install them

Yay! You only really need a front disk if you're going to be riding well kept and okay trails

If you want to keep suspension on the front, look for a used fork that is compatible with disks


EDIT - Cheeto has a good idea - get a Dart 2 fork for 80 bucks off pricepoint. make sure it can run disks though

If my SR Suntour P.O.S can run disks, I'm sure the darts can.

P.S The dart 3's aren't that mush more expensive, and it's still better than the stock crap.


Dont they make a disk brake adapter thing?

My frame doesnt have disk mounts, but its got a few holes above the derailer mounts.




EDIT:
http://www.pricepoint.com/detail/15674-315_ROCD27-3-Parts-59-Forks/Accessories/Rockshox-Dart-2-80mm-Suspension-Fork-'07.htm The dart 2 is 80.00 right now and is both disk and V brake compatible. The V brake bosses are removable if you decide to go disk.
But if you go disk brake route, you'll also need a new hub for your rim.

$80 is barely over cost. How do they make money?

No. Avid makes BB7 disc brakes for mountain bikes as well as road. The 7 has an extra adjustment pad. I have a set of them on my SS and they are indeed for MTB. It even says so on the caliper in case I forget.

The thread you are thinking of was really supposed to be about putting ROAD discs on a MOUNTAIN bike. What nonsense it devolved into is any ones guess but I believe the original post wanted to put road equip on a mountain bike.

Could be a loss leader or it could be their cost is lower by a profitable margin to sell a product for $80 and still turn a shiny coin. It might be last years factory overstock, who knows.

Wow! Thanks for all the info, guys. Sounds like a new fork is in the cards, after all. How does this sound? Stock 820+Dart2 fork, m324 pedals, and XT M770 brakes. It sounds like the brakes would be a big step up from the stock ones, obviously the pedals will be an improvement over the stock plastic platforms, and then the new fork to replace the Kappa. It sounds like getting front+rear discs on this frame isn't logical, if even doable at all, and I'd rather not have one disc and one v on there. Once again, thanks!

Edit: I see that a 2007 Dart 3 fork is about 130, rather than 80 for a Dart 2...is it worth the difference?

$50 each for XT V's seems kind of high. Pricepoint has XTR's for less than that...

Personally, I'd rather get the cheaper Avids (http://www.pricepoint.com/detail/119...vers-COMBO.htm). Unless your shifters and brake levers are integrated...then the individual calipers are $25... http://www.pricepoint.com/detail/144...Brake-2007.htm

Depends. I'd say save the shiny bits for some new cables and housing. There is a reason for the price difference and only you can determine if you need it. You don't by the by, another option (and one I would have gone, had I not had the Black hanging on the wall) is too slap a surly 1x1 rigid and ride off into the sunset. Oh, 'shiny bits' is money if you had not copped to that yet. I'm thinking of using more slang, if I don't know of a slang word like "copped" I'll just make it up. Ergo, 'shiny bits' as money. Of course now I'm flush with slang words for money;Dinero, Ducets, Cash, Bills, Ded Prez and so on. My shiny bits pales in comparison. I am now retiring it.

Cool, just for an update, it sounds like I'll be able to pick up a new Marzocchi MZ Supercomp really cheaply from a friend, so I'll likely end up with it...from what scouriing I've done on the forum, it sounds like it's an ok fork. I'm only 130lbs, so if there's not tons of travel, no biggie.

For those of us that don't know, you should explain why you are making terroristic threats of violence against my person. Have I insulted your religous views in some mannner?

I would most likely agree with you on this one profail, if he was saying it serioulsy.

although I'd drag said person behind a truck before I did the stabbing.

Supercomp isn't that bad of a fork, I've just heard it's not as adjustable as others.

had a trek 820 rigid in '93. gave it the panaracer smoke & dart tyres.

i really wouldn't lash too much new gear on it other than the bare essentials (erm... tyres), but that's up to you. mine simply was not worthy of fork or groupset upgrades. you can still get out on trails on it & save your money for a better bike later on. i did just that, trek 970 rigid - true temper oxII frame, which i felt was worthy of fork upgrade, SPD's, choice saddle etc...

so yeah, my advice just give it good tyres & thrash it 'til it's dead!
