Lightweight track frame with brake mounts for crit use?
Moderator: robbosmans
So I'm considering building a singlespeed bike for crit racing - considering all the crits I tend to go to are on flat airfields or race tracks, plus it sounds like a fun project and a bit of a laugh - as I don't take racing too seriously.
I'm struggling to find decent weight track frames that will take a rear dual-pivot.
Any ideas?
Must be available in 60-61cm. Aluminium preferred but will take Carbon if options are limited.

Why can't it be a normal road frame and you just run it as singlespeed?

I don't want a tensioner, and don't want to limit my gearing choices to magic ratio.

Fair - a singlespeed frame with racey geometry then.
Are you looking to do fixie crits or just regular crits? If the latter, it's rare that you don't need at least a bit of gear range to cope with wind, slight grades, or just with corners and accelerations. You can reduce to a 1x10 or 1x11 and put a close ratio cluster on the rear and have a very nice setup. You can also get an older bike spaced for 9 speed or even less and again do a 1x setup with a similar close ratio cluster and manage, at less money, an even stiffer wheel set and a bike you don't mind crashing.
If you want a single speed crit bike specifically for single speed crits, a la Red Hook, almost anything will work. The events are short enough that a track frame is fine as long as you can get suitable tire clearances (a lot of track bikes, especially older ones, barely give you clearance for a 23 mm tire, if that), and a little extra bottom bracket height isn't bad. But there are so many variables to consider in picking such a frame -- head tube height, hub compatibilities (120 versus 126 or 130 mm), horizontal stay ends so you can adjust chain tension, bottle cages, brake setups, and so on). That's all a bigger question than I think you're asking about.

Get an eccentric bottom bracket or hubset, and a normal road frame. No need for magic gear/tensioner.
Italian frame-maker Sarto, do a carbon track bike
Tommasini do a similar thing in XCR racing steel, Alloy or Titanium
As both manufacturers are custom frame makers, you can have whatever add-ons you require - e.g brake mounts etc

Standard crits, single speed. I have no interest or desire to ride fixed outside of a velodrome environment.
You make some valid points here. Basically my situation is this. I used to road race and crits competitively, as part of a team. Nowadays I'm more interested in Audax bikepacking, lightweight touring and distance, so when my racey road bike got hit by a car, I got myself a relaxed disc equipped endurance bike to replace it. I'd be looking to build up a relatively cheap and fun fast bike, and thought it would be a laugh to have it singlespeed (as I currently commute SS and really enjoy it). I'm not looking to race competitively.
Good pint re: tyre clearance, I'd not considered that. I'd want to run a 120mm OLD SS specific wheelset (or flip-flop for dual freewheel options) with 25c tyres, if possible.
"Horizontal stay ends so you can adjust chain tension" - this is basically what I'm referring to by saying "track bike". One bottle cage would be required - another thing I'd overlooked.

Interesting! I'd not even thought about this! Thanks for the idea.

Thanks, worth a look!

I have an older Jamis Sonik track bike and it is alu with drilling front and back for brakes.
Might be worth checking the newer model or seeing what is available in NOS.
In the past one could order it as a frameset, not so sure if that is possible now.
