Is this a part I would use for a 1x10 conversion on my trek 4300disc?

I used it for a conversion of my Lapierre Zesty 327 from 2x10 to 1x10 and it works great. Never dropped a chain (I have a clutch rear mech). I did not need any special spacers but I believe the 4300 is 3x10 to start with so it is possible you will need some spacers to help the ring align more with the middle of your cassette. Can't be sure without seeing it however.

I used mine on a 2011 Trek fuel Ex7 and it works great. .not sure on your model but for the money give it a try. .. I would also order the shorter bolts or spacers

That would depend on the space between the fork. It would be 10mm wider. It is always recommended that you use the size specified, unless you've changed your wheel.

if the frame is 27" no problem. I use this in my Trek 8500 and works great.

Hello Gustavo, Yes they will definitely fit, with no problems. You may need a new cassette and 2 spacers. I believe that your Trek 850 is a 7 speed if i am not mistaken; If it's a 7 speed you might need 2 spacers. The great thing about these wheels is that they come with 2 free spacers. These wheels are number 1 sellers here in my store and are the best upgrade can you do for your bike. Hope this helps

Mainly asthetics. Both are 2x1 activation and Shimano compatable. Should be interchangeable.

I made the conversion on my wifes tricycle. The conversion works very well. Make sure you also order the correct fulcrum lever and a shift cable cup that screws into the fulcrum lever. These two items did not come in the kit. LC

I believe that you are good to go. All of them area sstandard size. If different any of the "big box" hardware stores will have adaptors.

In my opinion,you could turn anything that will fit PROPERLY on this unit. Remember this is a small unit and there are limitations

I purchased this to use on a Tricycle conversion kit from Bicycle Designers. It was too wide to use on that. This conversion kit is actually a Sturmey-Archer 5sp hub. You can get the specs on the Sturmey Web site.

It should, I used it for MTB single speed conversion. At the time and still might be, it was marked as free return, for the price it's great too. Good luck.

I used these to replace the shifters and cables on my Trek 4300 mountain bike. I completely removed the old cables from the bike along with the old shifters. These new shifters come with the shift cables attached. I reused the cable casing that was on my bike, applying lube to the inside of the casing before threading the new cables through. The installation of the cables was easy. The adjustment to the derailleur after the cables are installed is a bit tricky. The best I can offer on that process is to either research online, find YouTube videos, or take the bike to your local bike shop and pay them to make the adjustments.

I really doubt this will fit your needs. My fork was a 1 inch. So this 1 inch to 1 1/8 inch conversion was perfect for me.

My bike had a removable seat and a 1 inch post. If your TREK has the same, it should fit.

Yeah, it will fit. You will need a 9 speed chain for sure. The front shifter on a 4300 is designed for an 8 speed, so you can tweek the derailleur until it just barely works, or buy a new 9 shifter too.

Yes no problem. But 2 1/4*85 will not work as suggested below, unless it has a small core. Be careful what you buy. But this will work.

The fit tool on Amazon.com says yes and adds this note: Notes: Combined Manifold And Converter Assembly, CARB Compliant: No

With a 9 speed chain, probably. It would not know the difference and 1x9 works fine in my experience. But instead of subjective answers, email race face :-)
