Bucklos / Lutu Air Fork Tear Down | What's inside? 

The stickers are made to be able to be removed if you don’t like them. Also I’ve ridden that very fork on my old bike (I’m 200lbs and 6’3”). I’ve beat the snot out of it on jumps and drops for a solid few months without and trouble. I recently sold my bike to build another and it’s still going strong with the buyer (he’s roughly the same size as me). I think that’s more than what you can ask out of a $136 fork in my opinion. Safe riding!

I have a bucklos air fork on my bike. It's been on there for a couple of years now and gotten its share of trails. It's still holding up fine. Worth the money imo.

Awesome to see you working with your son on the project! Have a good ride.

Love the way you explain things Dave!

5:36 was the best part for me you showed me something I didn't know about the forks, top review lad...

Bought a Lutu 27.5 as part of an 26er mullet bike experiment several years ago. Over 1000 miles ridden on this fork. Nothing more than XC oriented trails but never a failure. This invovled two different riders weighing in at 130 and 170 lbs. Also, this helped bring aluminum bike to under 30lbs and improved geometry slightly. I can't complain and feel that this is great bang for the buck if you are not a heavy or abusive rider.

Great teardown! Just got these, excited to try them. First impression was positive on my end - no trouble setting brakes up and not a scratch on it despite kinda crappy packaging. I emailed the company with some questions and for maintenance documentation and they got back to me same day. I think they're making an honest attempt at put out a solid product. Time will tell!

I put two of these on some electric assist bikes that we ride on asphalt trails and a little light dirt trails... so far they are great. I'm sure that hard mountain biking would reveal their weaknesses, but for what we use them for they are really nice... very smooth ride when combined with a cushy seat and a suspension seatpost.

I came from Christine's channel. I didn't even know what I was looking at until he partially put it together at around 2 minutes. I'm not from the world of biking. I didn't even know this was a thing 😅

I always wondered what the inside of a fork looked like. Now I know. 😊

Hi Dave I follow Christine and I just love your family so I thought I would mosey on over here and start following you ☺️

lets have some trail footage so he can tell us what he thinks of them!

I've had these for a year, using them for XC on my hardtail. The Lockout failed after a few Weeks on them but they are still stiff enough for me when pumped up and make my Giant Talon bike so much lighter. They don't feel strong enough for anything other than Road/Path

I bought the 27.5 version last month for 144canadian just insanely cheap. I needed a qr fork for GT idrive 5 parts bike that I built up for city riding with michelin country rock 1.75 tires at 65 psi with 5 inches of suspension is really fun to ride and this working great .I am shocked at how good the fork is for the money. Btw the 27.5 fork have is actually 120mm travel as tested and measured. Thank you for the great video as I was wondering what maintenance it will need and looks like just seals and grease from your video. It replaced an old heavy marzocchi bomber fork that weight over a pound more and had blown nitro piston .

I totally agree with your assessment. Your son is probably going to outgrow the bike before you need to replace the fork. Even if you need to replace it, 2 of those cost about the same as an entry level name brand. I still use my old walmart bike spring fork with no rebound, non lockout; I just spray with lubricant with PTFE because I cannot disassemble and cannot even see what it looks like inside. Steerer tube is even smaller than 1 inch. Cannot replace it with anything.

I've had a Pasak 20-inch air fork with rebound adjust in my Aliexpress cart for almost a year now. I intend to install it on my Dahon Jetstream, a full suspension folding bike that I ride on some light trails around where I live, and I'm looking to get talked out of it. 😁

All forks offered on Amazon, Aliexpress, Alibaba etc are from one manufacturer, they just stick different stickers on the forks ... 9:13...its Aluminium

Better than a spring fork😆

So I assume for street/beach riding these forks are pretty decent. I installed these on 3 of my fat tire ebikes, where they replaced 2 cheap/heavy spring shocks & 1 solid fork, seem okay so far.

I just got a nishiki Pueblo and the forks are prob 40 bucks so this might be a decent upgrade

If you want for your older boys you could get the dnm USD 8 dh fork its not crazy expensive and it has 203mm travel.

I wish we could see the air spring chamber

hey guys i have a 120mm Chinese air fork also and overall I am pretty satisfied with it. it has plastic bushings instead of foam rings which is kinda disappointing but this fork performs pretty well. and I have bottomed out the fork quite a lot and everything is still working well. overall I wouldn't recommend these forks for any downhill or extreme riding but xc and doing jumps on these forks works well. keep in mind I only been using these forks for a month now so I will see if it holds up in the future.

This seems like a redesign of an old fox fork like a FIT CTD damper, its likely an old design no longer covered by patent, made with cheap manufacturing, so as long as its not that cheap its prob still a decent fork, if not a little outdated on the damper

How much and what brand fork oil did you put in when you found out that there was none in there?

On Amzon, one complaint was that you didn't actually get full travel out of the forks. The other was that upon receipt the fork wouldn't hold air.

Did you fit them and pull the front brake?

How did it hold up? Thinking of upgrading my kids giant 24" with it. Great video

im planing on getting these for my entry mtb as an upgrade since i only have 80mm travel coil forks that are a little scetchy, i do 85% city riding with about 15% of easy\intermidiate xc and flowy single track and so far it has been good for a year but i dont feel super secure on it right now as the forksa have a little play in them i think this could be a nice cheap upgrade. any tips?

Love the way they just use the adjuster knob from an old model of manitou fork. Someone must have a box of excess of those. Probably the reason it has clicks even though the adjustment in the actual cartridge damper is evidently just an on/off lockout.

Ok was wondering if it work on my Dirt Jumper. But you reading the yellow label answered my question.

Regarding the lockout, that small amount of movement in the start of the stroke is pretty much cancelled with sag. Just an fyi. I would have loved to have seen the internals of the air spring

Have you removed the air spring? I'm looking at using a spacer to reduce travel to 80mm.

The fork lowers are actually made from metal but it's magnesium alloy and it's very soft metal. Not the best material but I haven't broke one yet. They are just prone to stripping

They’re good forks for the money 💰

They are decent forks for the price so long as you use them within the activities designed for, the red oil in the air chamber is not uncommon and is used to help seal and lubricate the piston, the lowers are made fully of magnesium which is incredibly light and lighter than even aluminum and so might feel plastic or cheap but that is usual for a mag lower. As for oil in the lower they are a lot like suntour in that they do not use oil in the lower just grease and even some of the more expensive brands do not use oil

Wish I could have tested mine on a jump lockout blew out before I could try

What size of bike did you put this on? Will it fit a 24” bike. And will it accommodate calliper breaks or just disc? Any info is helpful thanks.

I like your video

Did you remove the spring? I don't see it in the video. Can it be removed?

My Bolany fat fork with rebound works about the same as yours. You should lubricate the stanchions to try to get some lubricant in the plastic bushings before installing it on the bike. The lowers are magnesium, which sorta feels like plastic. It has to be made of metal so the dropouts can handle the clamping force and load of the tire.

I bought the same fork just with gold stanchions I had to return it because as you mentioned the brake posts were machined poorly, my disk brake was rubbing no matter how many adjustments i made. I got a replacement and this time it was a different problem I mounted the brakes and my brake rotor was hitting the cotter pin at the top of my brake calipers. I solved this by putting a washer between the brakes and the brake posts to raise the brakes up a little bit. Other then that I've been using this fork for over a year and i've had no problems with it, it's used for some moderate trail riding and on streets. Also could you add oil to this fork, or do you think it would leak out?

It 'seems' plenty good enough. Did you add any and what kind of oil to any of the lowers upon reassembly? I am replacing a 2002 Manitou 6 Comp 100mm coil fork. I took it apart for the 1st time ever bc I wanted to be 'responsible'...lol...The plastic access nut on the bottom was seized and I had to drill and easy-out it out. (I hate plastic essential parts). There was not a drop of oil in it. I remember some draining out 15+ years ago when I stored the bike upside down. But I didn't think much drained out and it seemed fine...lol...On teardown 2 weekends ago it had no rusty parts with lots of grease. I am pretty sure I could make some fabrications to put it all back together without it leaking. I am thinking of buying the fork you just covered. I might even go cheaper to a Mercoa $90 air fork that has no rebound adjustment bc I never really had or needed it...lol...I am 5'10" 185 lbs and just do xc and lots of wheelies. Does rebound adjustment really matter on an air fork? Thoughts on your sons Bucklos LUTU after this short time. Love your channel BTW.

I think they beat the brains out of the name brands at a really honest price.

Did they have foam seals or a place for them? In case you want to convert to oil bath

is this the 100mm or 120mm model? you saved me from another day of scanning amazon unable to choose. il take this one as a cheap backup thanks!

It has "Solo Air" on its label lol

Most of the better forks out there have tapered steerer tubes, so you'd have to change out your headset too.

QingSS Mountain Bike Front Fork, Air Suspension MTB 26 27.5 29 Inch 140mm Travel Rebound Adjust Ultra

Nice video, although I have the same fork and I can lock it out even more

Looks like a suntour xc fork... Probably is a suntour now that I think of it..

You dont want any of that plastic coating on the break caliper mounting surface hence the tape.

How's the fork holding up? Did you toss some oil in both sides?

we have the same fork sir..i've been using for months it is nice good to use 120travel lutu fork.

Forks that they call downhill, have the same sticker.

I knew a guy from back in the 90s that had half of his face ripped off from a shitty dual crown RST fork. Don't skimp on forks folks.

For a $137 thats a great deal. :-)

Can't you get a rock shox recon for not much more?

If you treat them right I’m sure they will last plenty of years...

I had a bad experience with a Bucklos Factory 32 140mm fork that I installed on my 26" bike. After about 300km in the city, I noticed that I was losing oil from the rebound screw. No help from Bucklos and I couldn't find anything on RU-vid to solve the problem. The lower air side screw spins in a vacuum and does not want to be removed and does not want to be tightened again.$#%&*(*(% To help those who wonder how many milliliters and what kind of oil; 5ml / 80W

So how long did the fork last?

These are just rebranded suntour forks with a newer damper. Has the same air spring, seals Nd parts as an xcr air but has a newer damper. It's crazy how no-one has really noticed this. They go really well with 15-20wt fork oil in the lowers, some foam rings and better seals. I'm running extra float fluid in the air chamber to ramp up the progressiveness at the end of the stroke as well as foam rings and 15wt fork oil as lower leg lube. Wolds apart from what it was when received. These newer style dampers can be had for $30 on eBay and can be retrofitted into any fork... I've thrown one of these dampers in an old xcm laying here and a dnm fork. The newer models of this fork have a different casting for the lowers as well as I just got another a few weeks ago. This set of lowers has metal bushings instead of the plastic bushings in the older lowers.

Lower forks are magnesium, not plastic...

Do you even know what the fork settings do? Or are you just clicking things and going look at that?

I wouldn’t recommend these. Got exactly these and a stanchion snapped inside the crown on one of the threads that holds the damper in. Fell apart when I was pushing up the hill to the top of some dirt jumps but I would have been screwed if they broke when I was riding

more lighter is better then sr cxt

Generally, the camera man should stfu, but here it really works. Keep it up :)

yo they think that with 150$ they will get a fox 32💀

Using a Cresent wrench explains alot. Lol you bought a Amazon or ebay fork sir. I pretty sure you don't plan on heading to whistler with it plus it's for a grom. Hey something is better than nothing until it's upgrad time. Lol I'm just happy to see lil groms stoked about riding and learning about mtbs.

I got 2 and ill tell ya what i think: got the fat bike fork for my framed. Had the local bike shop put it on. Picked it up brought it home held the brake pushed it down pss psss psss seal blown brand new. Back to Amazon replace it. 2nd fork put 90psi in it pushed on it gor 10 count…… 70psi. Put 90psi back in left it in the corner for 4 days……40psi reurn refund This don’t hold air for shit. Totally worthless.

Do not use this Wake handlebar .My friends dropped from little drop and IT broke

Buck loose..

Anyone buying these is in for a shock, no pun intended, they are garbage in fact dangerous garbage. 5 rides and 2 strip downs and I took them off and threw them in the bin. OK the damper lock out seems good but after 1 1hour ride the stiction and play in the bushes is outrageous. Genuinely the worst fork ever made and I go back to the 90s. In the UK they don't have the warning sticker so never ever use these on proper off road. Better still don't buy them just get second hand marzocchi lopro.

Can't you afford real wrenches? really crescent wrenches, good way to booger a soft bolt

I can’t imagine bucklos is a “real” company. The most likely just reverse engineer other products to fit the niche of cheap bike stuff. Like all the other Amazon brands, the probably just pump out cheep designs that they can find.

Welp ya get what ya pay for I guess

Junk!

I wouldnt let my kid ride those anywhere other than the street
