What upgrades would you start with?

I'm pretty new to the biking community and plan on doing it for mainly fitness. I'm 6'1" and 260 lbs. and I opted to go the more affordable way and find a bike used online. I bought a 1993 Bianchi Nyala with all Shimano Alivio components and a chromoly front fork. I plan on finding a decent front fork that will hold my wieght nicely but have been unlucky thus far. Anyone know of one? After about 1 hour of riding my hands hurt like hell and I have to alternate hands on flat areas to give them a rest.

The guy I picked up the bike from weighed AT LEAST 2x what I am. And the wheels are out of true and the brakes are pretty worn out.

What upgrades that are affordable (important) would you start with and what upgrades would you throw on in the future? The bikepedia for the bike doesn't say much about it. Please don't flame and say "You should burn the bike, and buy a better one", "Trade it in", or "Stop eating at McDonalds". I've been a big dude my whole life and I've heard them all, and I like this bike. =)
Thanks!

Hi and welcome.

First off, bring the bike to a local bike shop (LBS) so that it can have a good once-over. This will take care of the wheels that are out of true, etc. You may be feeling hand numbness due to improper fit. This may be alleviated by simply changing how you sit on the bike and again the LBS will be able to help you out by properly fitting you to the bike.

The bike will be great and you shouldn't knock it, including the fork. It will be able to do what you need it to do. Don't worry about upgrades right away unless the LBS tells you that you have a part that is toast that needs replacing.

well I used to be a auto mechanic and am very mechanically inclined. When I got it the gears wouldn't shift hardly at all, and the brakes were rubbing against the rims. So I adjusted the derailleurs and the brakes and it rides great now. The only problems I noticed is that the front derailleur rubs on the chain when the bike is in 3 gear on the biggest rear cog. It drives me crazy, so I was thinking about replacing my derailleurs because I can see that the cogs are all eyeball straight. The other problem is the rear brake on the right side of the bike (from a riding standpoint) has no spring to it. What i mean is if I take the cable off and push the brake to the rim it just falls down instead of pushing itself away from the rim like the others did. I moved the spring to a different notch on the frame (the 3 little holes) and it has a little more resistance but not much, so I'm thinking that needs to be replaced too.

Truing the wheels on the other hand... is definetly a job for the LBS.

How good are the shimano alivio components?

ditto on taking it to your bike shop

A general tune-up should run you anywhere from $40-90.

they may have multiple options for how thorough a job they do - just ask.

With the tune up, they may come across parts that need replacing (such as your brake pads), which will increase the cost a bit.

a fit might be free, or might cost you $30 or so. You may have to get a new stem or handlebar, but the shop can usually trade out with little or no added cost.

A proper fit will go a long way to helping with your hands, but the situation will improve as your legs and core get stronger. This will take some weight off your hands.

Welcome to the forums and to the biking community in general.
Good luck - and have fun!

the front derailur has two limit screws labeled l and h. you need to back out the h screw a bit.

for the rear brake, there may be a little screw running perpendicular to the brake pivot. if there is, try tightening that screw a bit. otherwise, I think you will need a new spring. (just to be sure - you say the brake arm just falls - towards the rim or away from it? - it is ok if the arm falls away from the rim - this is what is supposed to happen - you should only feel the spring when the arm get's close to the rim.)

these components are not the best, but i'm sure you already knew that. But it sounds like you have all of them working well, so I wouldn't worry too much about them. Basically, if something breaks or wears out, replace it with a better component.

I did try adjusting the H screw and it is out about as far as it will go safely. I also adjusted the cable. It was catching on the 2nd front gear from gears 4 to the top before. I'm thinking it might be bent.

About the brakes when I push it all the way to the rim it offers little resistance and just barely will fall down if I let it go. What I mean by that is it barely springs back enough for gravity to yank it down. It may just need a new spring.

What brakes and derailleurs would be a better set that are affordable. I looked on Ebay and the Alivio's are all less than 50 bucks (good for budget, but it's a replacement not an upgrade like I wanted). What's the next couple of steps up?

I am heading up the LBS today to see about my fit for the bike.

If I have read correctly, you said that when you're in the largest chainring [3-gear], and the biggest rear cog [1st gear?] the chain rubs on the derailleur?

This is completely normal. It's called cross-chaining. Because your chain is on the furthest front gear to the right, and furthest to the left on the rear, your chainline is more like this / instead of straight.

Best way to resolve this issue is to simply avoid cross chaining, because it causes premature wear and also puts stress on driveline components.

I had the same problem with hand numbness. Fixed it by moving the seat backwards on the rails (counter-intuitive, yes. But moving back moves your center of gravity rearward and takes weight off your hands and places it on your saddle).

Stop eating the bike, trade in a better one and burn down McDonald's.

I'd get a set of good V-brakes with kool-stop pads plus a general tune-up at the bike shop. Avid SD-7's are probably a happy center of price and performance (F=MA).

Sorry what I mean was the fastest set of gears. My bike won't let me shift all the way to opposite gears. So when my chain is on both far right gears.. it hits the derailleur.

Thanks for the tips on the brakes Luke I'll have to check those out.

And I'm replacing my grips A.S.A.P. it looks like someone tried to eat them (Not me! k well a little).
I had no idea there are name brand grips and seats though til I started looking on this forum.

Junkyard, I'm just used to the car street tuner scene... where people say "I wanna put a turbo on my non-turbo neon, how should I go about it?" and the usual answer is "Trade it in for a better car" or "Sell it and buy a SRT-4 neon" But as far as bikes go... people seem to admire almost any bike that isn't from x-mart.. or trek 820s from what I see.

I'm sorry. What a terrible scene to be used to.

Then drive the SRT-4 to somewhere where proper sports cars are sold and trade it in.
