Hello i need some advice please

Steelhead

Hello
I am new here but I need some help please
I got a Trek 4300 mountain bike back in 2006 or somewhere in that time frame
I got my younger sons bikes on that day to so mine was for me
well I drove truck over the road in those day and did not get to ride as much as I thought I would
and I put the bike up in storage!
Well one of my sons got ahold of it and well messed it up and broke a few things then put it back
where I put it!
So now needing it to get my body back in shape I dig my bike out and wooo what happened here
all I get is I do not know we did not do that!!!

ok so here is the damage rear to front
rear derailleur I can find on the web! do you have to get the same one??
hard part the axle shaft?? got bent where the derailleur mounts at the nut, to where do I find this part
the derailleur hanger I can find on the web to
the chain to I think I can find on the web

now to the front
the front forks the shocks chrome tubes have rust spots on them can they be buffed out or do they need to be
replaced if ? if so where to get these parts and how to replace them
on of the shifter handles is missing I think I have to buy a new shifter kit?

I took the bike back to where I got it and they looked at it and said to buy a new bike

I have looked all over the web trying to find a parts diagram for this bike or any trek bike
and I can not find any I can find a lot of places that want to sell you parts but I cant find any part numbers
for this bike!!

Can anyone here help??

I think your bike shop was correct, buy a new one, this was a fairly cheap bike at the time, by buying new you will get a much better bike for not a lot more than the spend on updating your old bike.

Any Shimano 8 speed mech and shifters will work.
Forks were rubbish to start, will be scrap by now.
Are you sure the axle is bent, and not the quick release skewer?

Bet thing is get second hand stuff off Ebay or the like.

Looks quite a nice bike to me except for the forks.

If the forks are still serviceable then probably worth sorting the bike but if not you have to decide how much is worth putting into the bike. I would suggest getting some rigid forks. Most front suspension is un-necessary unless you are planning on taking the bike seriously off road. Some rigid forks would be my suggestion. Looks to have a threadless headset and I'm sure are 1 1/8" so that is what you need. Worth a look on ebay etc once you've confirmed what you need. I'd start there before looking to do anything else because you may find replacing the front suspension forks is too expensive and decide on just getting a cheap s/hand bike. Look on shpock, gumtree, local auctions, ebay etc for cheap s/hand local bikes. You may find something basic for £20 that just needs a service without any expensive parts.

As above really, do it yourself with used parts (Gumtree/ebay) and it can be done quite cheaply and worth repairing, pay a shop for parts and labour and its not.

Some photo's will help diagnosis, especially as "hard part the axle shaft?? got bent where the derailleur mounts at the nut" is, to be honest, gibberish, the derailleur doesn't mount to a nut on any axle.

I have seen on very cheap BSO derailleur fitted to an adapter that uses the axle as a mount with a nut to hold it in place I'd be surprised if that was used on the trek. Also on same priced bikes, solid axles of low quality steel are used so could be bent.

The Rookie

Yes, but this isn’t one of them as you would find out by a google.

OK sorry for the delay I had surgery
Front fork is a rst gila 80mm travel got a number off the tag on the fork c002t8003172gt607123
Again the front chrome s have rust spot on them I found this

Do ya think this will work??
Now I might be wrong by naming this but here goes rear axle hub shaft
Rear wheel axle shaft where a the Chain gears are at you have the threaded shaft right side where the derailleur is at there is a nut and then a smaller threaded shaft at that spot on there shaft it is bent
It is shimano 8s parallax tage on the hub

The derailleur is shimano alivio sis index in the rear, the front is shimano 050 derailleur

Weigh up the cost of the repair vs bike value.

That kind of bike in my opinion is worth depending on condition £30-£60.
I've had a few people give me similar bikes to service and had to tell them it wouldn't be economic to repair as the cost of parts alone would normally be more than what the bike is worth and even if the parts were 50% of the bikes value I personally would look at other options.


You can buy any fork you want that is
1/8"
straight steerer
v brake compatiable
similar travel 80mm-100mm

Cost of repair + value you could get on ebay and see what other bike you could afford.

If you're local, I have a 26" wheel with 8 speed cassette, you can take it away for free. I'm in Bromley Kent.

I'd strongly suggest a rigid fork without suspension. Not only will it hopefully be cheaper but more efficient and stronger. suspension is high maintenance and un-necessary for most riders. If you need more comfort think about the saddle and thicker profile tyres. Suspension is heavy, absorbs energy as you ride and can fail and be problematic.

Something like this would be ideal. There is a £5 voucher code for orders over £30 so would bring it down to £27 ish and if you go through topcashback you can get some cashback on top.

You may find cheaper but you certainly don't want to spend more than that but not worth investing in them until you are sure the rest of the bike is ok.
