New Build - Frame Up - need advice on how to buy GroupSet
So because why not, I have decided I am going to build a bike from the frame up. This is a fantastic idea, except for the fact that I have no idea how to do this. I have a disk bike frame, with a BSA bottom bracket. Now I need a groupset. I need EVERYTHING. So my question is... how to I "narrow" down my groupset choices? I don't need to "cheap" out on this build, but its my first build, and the frame is inexpensive, so I don't really want / need Ultrega... I looked for Sora, but apparently those are hard to buy? I find a lot of packaged groupsets, but they all seem to have rim brakes?
Are there any recommended sites I should be looking at, is this going to be an Ebay thing? How can I tell a "legit" site from a .. not so great one...
I really think a Tiagra 4720 is going to be the sweet spot, what do you think ?

Try Jenson USA, Nashbar and Performance for decent prices and selection. I would have recommended a couple of UK dealers but they aren't able to ship any Shimano items to the US.
Years ago I had my LBS put together a "build kit" from QBP that included everything I needed for a bare-frame build and allowed me to spec personal choices such as gearing, stem length, wheels, handlebar width, crank length, etc. The package deal was a bit less expensive than individal purchases would have been.
Be aware, in today's environment, supply is limited so it may take you a while to get everything together.

You need to figure out what your budget is. Then you need to add everything up that you need. Groupsets can be expensive or inexpensive. Handlebars, saddle, seat post and especially wheel sets can add up to more than a groupset.
I will probably always be Shimano or SRAM for groupset choices. But if you need to stay in budget, then just stick with stuff you can actually find installed on current low tier (less expensive) production bike offerings from Trek, Giant, Specialized, Cannondale, Kona and etc. If the bike manufacturers shun a cheap brand, then maybe you should too.

Good idea pre covid, not the greatest idea today with shortages of parts/long lead times. For discs, even pre-covid, it was often cheaper just to buy a bike with them fitted if you were planning starting from just a frame.
You haven't identified much from your post, do you have a fork, what spec are the wheels (axle) you need, do you want hydraulic or mechanical brakes, Sora, vs Tiagra vs Ultegra, it's more than just don't want/don't need, none are compatible with each other, and all have different features, that you may or may not want/your frame requires..
You say you have a 'cheap' frame, check the specs in detail, is it cheap for a reason, i.e. its already obsolete when it comes to the specs?
With the limited info given, would look at how much your frame cost, how much all the parts you need would cost, if you can get them, and what time scale (spreadsheet time) labor costs if you can't do it yourself, and then what a full bike would cost, and if this is cheaper/easier.
There are other options for groupsets, but for a first time build, would stay away from them, till you know what you are doing/have a working bike, as compatibility & knowing what is good and bad becomes more challenging with this

Merlin will still ship Shimano to US but 105 is out of stock. Also Texas Cyclesport, but again, out of stock. You will probably have to buy parts piecemeal. If you aren't confident you can do that, the project is ill advised.

I would look at Bikes Direct (or their subsidiary, Bike Island) for a bike with good components but inexpensive frame (they seem to specialize in this), and transfer everything over, then sell the frame (and fork if applicable). I'm really surprised that my LBS didn't buy some BD bikes when supply of parts was non-existent since it seemed like good value (TO ME).

This is the Frame, I actually have not bought it yet, but I am quickly realizing that I may need to flip to a rim brake, just because of cost / availability of parts.

It is a lot harder to find groupsets right now than it used to be between no longer being able to source from the uk. and 2 sites that have groupsets are 105 or higher https://www.coloradocyclist.com/road-bike-groupsets or https://www.texascyclesport.com/grou...ade-kits-road/
did say road or mountain what type of disk frame
you need the below items. it is going to cost more than buying a tiagra bike...that simple,
also if you piecemeal components it is always more difficult (not impossible, just more difficult) to get everything working perfectly than if the components are matching
I would be really careful on ebay with groupsets shipped from china i did see this one https://www.ebay.com/itm/38439048450...cAAOSwa4VhPejj
wheels
cassette
chain
crankset
bottom bracket to match crank
front derailler (maybe)
rear derailler
brake calipers
brake rotors
brake levers to match calipers and maybe shifters depending on build
cables/housing/brake line if not included with brakes and shifters
stem
handle bars
seat post
seat post clamp if not included in the frame
seat
bar tape or grips
tires/tubes etc

You are probably going to want to stick with Shimano shifters. I say this specifically because they have great compatibility reference sheets you can use. Whatever group you end up buying if it is newish and/or a take off from something else you will probably not have post mount calipers. You will need to figure out whatever group you end up with and reference it against a set of post mount calipers that will work.

My most recent bike I got just before C19 hit has non-thru axle disc wheels, and I picked up a couple of sets of wheels at the time, knowing that replacements would be hard to find in the following years, and that was without C19.. happening. If you can build wheels, not so much of an issue, but at the same time, wheel building isn't a massively cheaper option vs just buying an off the shelf wheel.

Supply is going to be a legitimate challenge. Note that you will definitely not save money doing this over a new bike unless you scour for really good deals on used parts, which frankly it doesn't sound like you have the experience to do. I also generally think that properly maintaining a working bike is a better way to learn bike mechanics.
Ignoring all the above, the big choice is between hydraulic and cable actuated brakes. Hydraulic is a big upgrade in my opinion, though installation will be harder for a novice mechamic. Probably the cheapest good hydraulic option is RS405 non-series Tiagra level shifters/levers/calipers. Note that these shifters are only compatible with 4700 series derailleurs.
If going cable actuated you can use most any road groupset.
Hard to give advise more specific than that. Really it seems like you're out of your depth here. You can totally do it, but you're going to have to do fine real research, and will also have to invest a fair amount in tools to do a professional job.

For the OP, if the frame has dropouts like in the image, it's not thru axle, if it was, the image would have the axles in the image, as these are suppled as part of a frame/fork, where as non-thru axle aren't (they are part of the hub)
One other thing to note about that frame (the LTK115-D) the disc tabs are for IS standard, this is obsolete for road (still standard for MTB's) if you went with road Hydraulic brakes, you would need to look for an adapter or to swap the calipers as almost all road hydraulic discs are now 'Flat Mount' regardless of brand when sold for road bikes. That frame looks to be spec wise about 5 years old, and a lot has changed since then.

Building a bike from the ground up is extremely rewarding.
So is sourcing the best deal on just the right parts for "you"
And assembly isnt that hard either IF (big IF) you have the tools.

- Bike stand (makes assembly much easier)
- BB socket/wrench
- Cassette socket/wrench
- Proper headset press tool (not a pieced together threaded rod & washers setup - ugh, so frustrating that is)
- Proper bike cable cutters, or at least a Dremel with a disc cutter attachment (gottta use one to prevent damaging the control cables)
- PVC pipe to drive the crown race down
- chain link breaker

It is a super old frame, its also super cheap. For everyone that keeps reminding me
- Yes, I know this is not a cheap project
- Yes, I know I have no idea what I am doing, but I am going to learn, and I am learning a ton already from this thread - Thanks
- Yest I know this will take "a while" - but I don't care, the journey is part of the fun
- Spend a bit more money up front - get a newer frame
- I really didn't realize how much this mattered
- Due to parts availability - try for V brakes if possible
- See if I can get the parts I want - at a price I am willing to pay - before I order a frame (instead of ordering a frame and figuring it out later)
- Figure out this wheel thing - I think I am ok with quick release, and "used" wheels, but find the "used wheels" first.

Dont forget the tools needed to install the parts!

I also bought the Park Tools "home mechanic starter kit" - I am still going to need more, but its a start.

Thats a great stand!
Ive seen people do both but personally I always try to clamp onto the seat post . It would break my heart if I crushed/dented a frame tube

It's easy to tell which is a 'legit' website. Ebay is a legit website. Alieexpress is a legit website. A standalone website selling groupsets, like sale-groupsets.com, would most likely be a scam website.

I just pieced together on ebay a SRAM Rival 22 mini group for my old CX bike. Next I'll be piecing together the hydraulic version for my road bike. Seems like all the complete groups available are overseas. Don't limit yourself to Shimano, I'm a SRAM convert. The components look to be a nicer quality, the shifts are firm, I like the location of the limit screws and the front derailleur is awesome with no chain rub. The brake lever feels more solid since it doesn't move sideways to shift. Even Apex looks nice for a budget build. Campy used to be my favorite manufacturer (don't like the direction they went) but SRAM is similar to me.
