For 2022 the Handmade Bicycle Show Australia (HBSA) returned to Williamstown, a short skip across the bay from Melbourne’s CBD. Filling what was once a large shipbuilding workshop, the open room was a buzz of familiar names and faces from across the Australian builder community.
While the show leans toward the road and gravel markets, the presence of custom mountain bikes has increased year on year. Having already looked at the
latest from Trinity MTB, below is a look at a handful of custom steel bikes from
Devlin Cycles,
TOR, The Lost Workshop, and
Woods Bicycle Co.
You'll find more coverage from the
2022 Handmade Bicycle Show Australia over at our sibling website CyclingTips.

For me, a steel front triangle + aluminium rear parts (so do Stanton or Cotic) make more sense than a full steel system, but I might be wrong. Tell me what are your thoughts about the subject, I'm curious. Id really like to get such a machine one of these days.
Cheers!
The @waltworks guy made this frame, and I think its 7 pounds: waltworks.com/wp-content/uploads/2020/01/WW-FS-Front-Right-800x500.jpg
That being said, I don't get Pinion hard tails. Just get a normal hard tail with a Kindernay, Rohloff, or Affine hub. Kindernay and Rohloff are both lighter and more efficient than Pinion.
@hamncheez: weight is another question, and it's not a (the/my) concern, I mainly dealt about flex/stiffness and feeling.
@wyorider: you're completely right: all aluminium is the soft spot in term of lightness, stiffness, reliability, durability (... depends...), riding feeling, and it's fully recyclable (if things are well done).
To optimize Aluminum it shoudl probably be hydroformed, which requires expensive moulds. This locks manufacturers into strict product cycles, and can leave companies flat-footed, like when the 1st gen Enduro 650b was a 29er main triangle with a spacer and a modified 26" rear triangle, or like how carbon and aluminum based companies were stuck flat-footed when suddenly 64 degree HTA and 77 degree STA became the norm.
Did I say cleaning?. Cleaning.
This bike as built weighs 14.6kg. Thats for a 170mm travel big hitting enduro race bike. That is definitely not heavy. The front triangle is stiffer than just about anything out there and is definitely overbuilt. A great platform to swing suspension off. I have designed the rear to have a little bit of tuned flex so that there is great feel and feed back when on the limits of grip. These bikes ride smooth and are super predictable in their manners. It's not designed as a shuttle bike. It pedals great, sprints well out of corners. Is stable at warp speed through the chunk and steers nicely.
edit: P.S. the bike is gorgeous. I _love_ the fabricated rocker.
Thanks mate. .
Maybe it just isn't as aesthetically pleasing to my eye. Still doesn't take away from the fact that it's a beautiful bike.
As you can see in the current setup, the dropouts are about 2/3 of being at max length. Push that wheel forward and the wheel will get awfully close to that seat tube, if not touch it, if it were straight.
Also, Ian (builder and owner of the bike) is a tall fella. The seat post is set at his height, so no need to push the seat post down further.
If you're going to nitpick, do it properly.
@dreamlink87 If you want something that already exists, I forgot about these guys.

edit: actually, I should have checked Swarf first- the Curve is exactly what I was envisioning. Just too bad they're not building anymore!
Or a Starling Spur altho doesn't meet the 2 bottle criteria off the bat....(but can with some a Cycle Solvers bottle mount www.cyclesolvers.co.uk/product/bottle-adaptor-starling-murmur/10?cs=true&cst=popular ).
But I will take it to Les 2 Alpes and Aosta in w weeks, maybe that's better terrain than Finale for a high pivot. ;-)
I'd ask for 29 both ends and some paint, but bravo!!
A simple bike,
A simple drivetrain,
A match made in mtb heaven!
How did the Devlin builder embed the brass lines in the head tube and rear triangle - did they machine a fine line in the tubing and infill it? That is gorgeous.

Steel is Real!!!!! Yaow!
Same with fillet brazing. You can most definitely get away with not filing smooth. Curtis and Kam Fab in teh UK don't file finish but for sure 98% of teh bike industry do file their fillets. It makes for a better structure. No stress risers and teh transition from parent material to fillet weld to parent material means stress is handle better that in a angled unfinished fillet. I've done fillets at times that literally just needed a couple swipes on teh sandpaper and it was done so the fillets are done properly in the first place. Some fillets you need to over fill a little and shape back to get the smooth transitions as gravity and the surface tension prevent you from getting a nice shape off the torch.
If you prefer the look of unfinished fillets that's a different thing. Microscopically they are inferior to finished fillets and any builders worth their salt finishes them off to ensure a high strength structure.
-dont understand the downvoting, I'm not bashing anyone for creating amazing bikes by hand. It's not easy and my first frame is a pile of hot garbage. Just pointing out my concerns.
I'll find out, I own one of their FS bikes.
So I’d say you can’t just braze a frame with the same fittings etc. used on a welded frame, but if can be done.
But it’s moot. There are two very well known steel frame builders here in the UK, one fillet brazes (properly), their frames don’t break. The other tig welds (properly), their frames done break. Both are good methods of joining a steel bicycle frame, and many other things.
Fair enough and I wouldn't worry about structural problems here.
Don't want to be a total dick here but it's just that this is a show bike that you decided not to paint to show the fillets and those fillets are uneven around the edges and with pinholes in them.
I am not a frame builder but fillet brazed a few things at home, a frame during a building course myself and also own another fillet brazed frame where I didn't get asked or even charged extra for perfect fillets.
Bear here: I walked away from sticking metal together, to fusing it together in 1973. Messing around with Flames, Flux and other crap associated with Gas Torch brazing left My personal work environment 47 years ago.
You're seemingly committed to Brazing, and, indeed, your sweated joints that I see in some sections of your frames and your sweated tubing sleeve gussets - Fair Enough. The radius width you can achieve by braze fillets? - yes it can make up well for it's lack of strength compared to a fused joint. And, you've a process that enables different metals to be joined together.
One undeniable advantage of 'sticking' frames together by Brazing, and Soldering, Is the far easier way that tubes can be repaired / replaced than a TIG'ed, Fused joint, that's for sure!
You bought a TIG welder, didn't you? It seems everybody has one now - not that a 50th of them could use one properly, but's that's the way it goes - "all the gear, and No idea" is the theme of today.
Now, what I'm suggesting you might try, is TIG Brazing. You'd get your look / results that you currently have, and, as you became proficient at it, you could have the option of leaving , what can be, Absolutely Gorgeous beads of Bronze. Or, you stick to filing / sanding things down as you do now. TIG Brazing is Infinitely cleaner / healthier to deal with than Torches and Flux, too.
Go to say, Welding Tips and Tricks. Jody there is a supreme welder - I'm not given much compliments, but he is a fount of information.
Look for his TIG Brazing vs TIG Welding video(s) . And, he shows , basically what you are doing , with regards to a large arc / fillet to achieve strength and adhesion. Him hanging off a cycle tube until it collapsed showed that a good, strong joint can be made.
I do very little TIG Brazing, but, it's still in my armoury of metal working methods. The last I used it, was in repairing a couple of Harris XR69 chassis. If you want to see just how utterly beautiful Brazing can be, go type that out on your keyboard. They started as housing Suzuki GS / GSX/ GSXR engines, and are now being used to house FJ1100 /1300s and other big Air Cooled 4s, that they never housed in their original era. Beautiful things, but, they still have Braze joint problems, even with the superb workmanship they have.
Good to see you keeping on with your frames. I've thought of going to that show, but, while most enthusiasts are truly great to deal with I'm not one for dealing with , well, some of the weirdos / drongos that one encounters at such events.
Make a frame, show it on pinkbike and see how it fairs. Until then, show some respect to the people out there trying, clowns.
