Lock Spanner, Bike Bottom Bracket Removal Tool, Bike Bottom Bracket Wrench for Removal Vintage Bicycle Bottom Brackets Cups Lock Ring

I thought i wanted a cool sexy modern 1x setup on my bikes until I started riding my well set up 3x bontrager and 2x morati with a secret twist - a modern RANGE cassette for a 1x bike. Now I am firmly in camp 2x. I don't ever need the full 3 ring affair, but a 2x8 or 2x9 with a 24-38 and a modern range 11-40 or 11-42 8 or 9 speed rear is an absolute monster of speed and climbing, and you never worry about chain dropping. If you want to address chain slap, a $50 deore 10/11s clutched deraileur fits on an old bike and works with your current shifter for 7-9 speeds. I would honestly stick with 2x on anything except a proper mountain bike or MAYBE competition gravel bike. I would even keep a 2x for a long distance bike. If the derailleur fails or you have a chain ring fail, you have a spare! https://a.co/d/0hoGEb03 This will get you converted to a modern rigid external hollowtech bottom bracket with a 2 speed. Just make sure you use cheap digital calipers (mandatory tool, cheap is fine but get a cheap digital one for convenience) and to measure the outside size of the bottom bracket and use one or both of the spacers included with the BB, because your trek is probably a 68bsa, which needs both of the spacers or it won't fit. You need an external Bb wrench (don't worry about torque, just as reasonably tight as you can get with the hand wrench, get the $23 5 in 1 aluminum one that will do any external Bb.) don't accidentally torque the crank arm bolts to the bottom bracket setting like I did yesterday lol. Impressively the crank arm threads held and the bolts snapped at like 30NM. Had to extract it and put new bolts in. You will need an internal bottom bracket tool, get the combination kit that has a crank puller, BB aocket is like $13 https://a.co/d/0cxhhxpw the only tool you might need is a lock ring tool depending on your BB, but this is a billion times better than a flathead and a hammer and marking up your paint. Idk why it's $15 and no cheaper ones exist but this is worth your suffering https://a.co/d/06cv4p0P You need a cassette/freewheel tool and chain whip https://a.co/d/0d01obEd There's a 3 ring version too that's also great, if you want to keep the 3 rings, which is valid. Still gets you the more rigid external Bb and hollowtech cranks. If your bike has a freewheel, cheapest option is a new freewheel in the 34 tooth rear. Combined with the 22-36 2 speed chain ring and you'll get solid climbing ratios, but if you want modern and mega climbing (which I do) then you should just get a nice new $75 rim brake wheel with a Shimano freewheel hub on Amazon. You probably have a 130mm dropout spacing, I can't recall if the wheel I found yesterday for someone was a 130 or 135 hub but you can make a 135 fit. If your bike is a free hub, get a cassette. Bucklos or bolany, 11-40, 42 max. With a 22 or 24 little ring your torque ratios are genuinely hard to ride. If your bike is an 8 speed, just get an 8 speed cassette so you don't need to change your shifter. And a new chain for however many speeds you have. Just count the number of rear gears, so 7, 8, 9. Use the big-big plus 2 links method to size the chain. Park tool video explains it. You will probably need to adjust the third screw on the deraileur that opens the gap between the jockey and the cog so they don't kiss on upshifts. If you want to keep the deraileur and need more space, $20 wolf tooth deraileur extender. That will give you a better range than a TOP spec modern 1x, better chain retention, you get the climbing perk of being able to drop the front ring pedaling under load (under appreciated benefit) So if your bike has a cassette. That looks 8 speed I think. Get an 11-40 cassette. Adjust the deore lx deraileur to fit. Get a new chain if you need and size it. You really don't need more than that. If you want to get fancy with one step up, also get the combo external BB and 3x hollowtech crank setup on Amazon for $50, no need to change the front deraileur or shifter. If you want a sleeker 2x setup, get the external BB and hollowtech 2 speed I linked, and a Shimano 2 speed shifter - that front deraileur will work fine. If you desperately, desperately want a 1x setup (you might run into chain retention issues on an old hike, bear in mind) assuming that bike is a cassette, just get an 11-42 or 11-46 10 speed cassette. They fit on the same length freehub actually, the spacing is just more narrow. You will almost certainly need a new deraileur. Deore clutched 10/11s long cage one is about $50. An 11-46 might run into space issues with the adjustment in that bike, so beware you might need an extender if you go for that. Don't get an 11-50, you'll have chain line nightmares. I wouldn't go past 11-42 honestly. You'll also need a 10 speed shifter. Comes with cable, get new housing. For 1x up front, again the bolany or bucklos external BB and hollowtech crank combo kit is your best bang. I'd go with a 104bcd 4 arm crank over a direct mount but either is okay, and you probably want a 30 or 32 at the biggest tooth narrow-wide chain ring up front. Don't go oval, you will have perpetual chain drop issues. The reality of that setup is you will have worse gear ratios, it will cost more to set up, it will be noisier because 10 speed cassettes are narrower between gears so they just rub more, and you'll be more susceptible to dropping chains, so I'd probably recommend a chain keeper. Which is even less efficiency and more noise. The sweet spot of cost and performance and looks is the 2 speed 2x8 for you. I'm doing that on an unobtanium morati 1.1 right now. I could go 10s 1x, but it looks and rides better with a 2x9. The 2 speed crank and BB kit I showed you, a 2 speed shifter, new 8speed chain in whatever fancy color you like (a gold bucklos or bolany hollow chain is like $15) and an 11-40 bolany or bucklos 8 speed cassette. Install the BB and cranks, cassette, size the chain, install it and then adjust the derailleurs (get yourself some cnc colored cable and housing kits for flare.). Or get a new 8s chain, cables, and that 11-40 cassette and send it with your current square taper 3x front for $35 all-in.

Long post split into a few (I put a couple hours into this for some reason - DM me if you have any questions) but this should be comprehensive and will get you started with a series of easy to do upgrades that will get it riding like a $2000 bike. Feel free to DM me with specific questions, I've done almost all the mods and cobbling together of parts imaginable and found basically the best value stuff. You have a bike that you can cheaply modify into something that will be comfortable, reliable, fast (the 3x front setup is WORTH keeping) and really fun to make YOURS. Park tool's youtube page and bikespeeds videos for all your service needs. A lot of the standard items have budget versions and brand name versions that are robust and reliable. First step is replace what you need to get it safe. You can address a TON of other stuff next to get it set up just for you and make it something you will adore. I'll cover that at the end. Step 1. basic tools and get it mechanically working. If you want to do this AS CHEAP AS POSSIBLE at first, you'll be replacing the parts you just did soon as you upgrade, but just DM me if you want me to get you on the road for as cheap as possible first. These upgrades however will be abject improvements to every single aspect of your ride, and if you enjoy the mechanical engagement of the bike, you will like riding it with other mods more too. Looks almost always come second to basic safety and comfort. Tools we need - some specialty mandatory tools, and a few very quality of life ones. 1.) duratech pliers, $17. These CLOWN on the expensive park tool ones and replace the need to also have housing and cable cutters or cable end crimps. https://a.co/d/01mxVpon 2.) metric ball end L shape T handle hex wrench set. Harbor freight has a $20 pittsburgh one that I use that came with a stand, but this will do the job great for $20 https://a.co/d/02xr3RVs . Alternatively, for $10, this will do the job too just as well really. And color coded handles is nice. I might actually get this instead https://a.co/d/0fObxD6N 3.) external bottom bracket wrench if you want to do the better upgrade for the worn crank chain rings https://a.co/d/04JBo9te 4.) headset wrench (just one, you need one thin one to hold the bottom lock ring of your headset and an adjustable wrench can hold the top one) $13 https://a.co/d/04JBo9te 5.) pedros tire lever $8, best ever https://a.co/d/05qK48E4 6.) spoke wrench for various size nipples, $6 https://a.co/d/05qK48E4 7.)

Lifetime supply for $14) https://a.co/d/03Ry495U 16.) boeshield t9 for chain lube and anything that needs a lighter oil or rust protection. This is a miracle fluid, $9 will go a long time https://a.co/d/05pkpfNH 17.) (optional, recommended) bike repair stand, $45 https://a.co/d/05pkpfNH 18.) a mini bike air pump is worth having. These are $25 and will save you https://a.co/d/02gi4VlG 19.) a multi tool. the crank bros one is kinda king for $27 https://a.co/d/02gi4VlG 20.) even with sealant tubes, a micro tube patch kit is worth having for $13 that fixes tons of tubes pretty permanently https://a.co/d/01Qcu6cs 21.) (optional, recommended) a small torque wrench. $35 https://a.co/d/0hndQDrE - you can't torque the big things like the bottom bracket cups or cassette lock ring with it, but those things can be man-tight and fine.
