This also supplies you with some practice joints for welding later. When you're first starting out, it's best to cut a few lengths of tubing to practice your mitres. It helps to employ an online tool such as the - Metal geek tube coping calculator. Hand filing with paper templates is the way to go for starting out. There are several ways to go about it from hand filing (really not that hard to master), use a lathe (my preference) ot a milling machine, or buy a dedicated tube notching tool. Tube mitering is the probably the first thing you will need to master if you plan on making your own frame. Once I am happy with all that, I then do the fiddly bits like, cable guides, the disc mount, rear mech hanger, and head badge. I start with joining the seat tube to the bottom bracket shell, then I build the front triangle, followed by the chainstays and seat stays.

Trying to document the full process of fabricating the frame has been quite a bit more difficult than I anticipated, but I suppose it can be broken down into five-ish steps Cutting tubes to length, Coping/ mitering tubes, tack welding, alignment check and finish welding, followed by a further alignment check. That gives me quick and easy references while I am building.ДЇABRICATION: Smaller steps ensure accuracy I draw out the tube junctions and also how they will fit into my jigs. To read a more detailed write up about hardtails, fork travel and geometry head over to BTR's blog here. Even with a 130mm fork, the head angle and reach goes from 63Вє/440mm to 64.5Вє/450mm between static and sagged. I find this results in your weight being thrown forward, the reach effectively increasing, and the head angle steepening. This is because the longer the travel, the more the geometry will change throughout said travel. I personally prefer hardtail frames with a short travel fork. This frame is going to be a 29er and will run a 130mm travel fork (2018 Rockshox Recon RL Solo Air with 51mm offset). As a hobby builder, though, I can't justify the price tag. Bikecad is the best option otherwise and packs a load of great features, such as Bike fitting, and has a built in tube coping template maker. I design all my frames 2D in Adobe illustrator (effectively pen & paper), It's not the best program for the job, but as I use it daily (graphic designer), I know it very well. Materials sorted, it's time to set about designing the frame. That being said, it took two years of racing all over Scotland and it earned a few podiums before it gave up the ghost. I've only had one frame fail and that was at the top tube where the gusset met, this could of been down to a bit of dirt in the weld, faulty tube, the gusset itself or many other reasons. The Columbus Gara tubing is standard 4130 chromoly and isn't the strongest option out there, but as stated, it's easy to work with and cost effective for a hobby builder like myself. If you wanted to get fancy and shave off a bit of weight, you could go with a double butted tubeset, but double butted is about two times the price of straight gauge. I like to keep things simple and use straight-gauge tubing, simply because it is easier to work with and you can also get longer lengths - and it's quite a bit more cost effective. I buy all my tubing from Simon at but there are lots more options out there (such as Reynolds). Want to make sure you are getting the most out of your new purchase? Our guides can help to explain some of the more technical stuff and give you every bit of information you need to know about hybrid bikes.For my brother: 26' wheels, 160/140mm travel, 64Вє head angle, enduro bike. Every bike is fully built and assembled by a Giant authorised mechanic before you ride away, so you can be confident from the first pedal stroke that your new purchase is ready to roll.
