Singlespeed & Fixed Gear - IRO Angus or Mark V???

SO...

I am going to sell my fixed Cross Check and buy a complete IRO with some upgrades. My initial intention was to go with the Angus because of the Reynolds tubing, simplicity, and the cool old school build I could do with it, but I am having second thoughts. The, also sweet, Mark V has the appeal of the threadless stem (I do love a nitto quill though), looks tough and it is a few bucks cheaper.

What experience do you folks have with these frames?
Pros Cons etc.
I am going to be mostly using this as a commuter/street racer.

GO...

thanks

Sames tubes. I would go with whichever frame works with the HS you already have.

I used to have the best of both worlds; A Mark V Pro.. but the seat post seized and got decapitated w/o coming out from the frame. So now I have a Mark V, which I like quite a lot. I'd like to get an Angus just so I could have the nice quill stem look, which chics dig. The Mark V doesn't get me much p****, I need to bust out my miyata for that. Go with the Angus.

The Angus doesn't have a nicer tube set? Why the more money?

Angus is Reynolds 631
Mark V is 4130

Reynolds is the reason for the extra cash.

thanks for the words, keep em coming

Hey! Looks like you know enough already. It's up to you now.

i'd go with the Mark V. you won't notice the upgrade in tubing, except maybe in weight (and i mean come on, you can always get a lighter wheelset, or drink less beers), but you'll definitely notice the improved performance/stiffness of a threadless steertube, and you'll definitely notice yourself saving some money.

As if. Icky. The only p**** you'll ever get with this approach is your own mang**na.

I noticed a big difference between my cross check and my angus - the CC would flex sprinting or on uphills while the Angus is like a rock. Of course, I've never ridden a Mark V so it's kinda apples and oranges. I do kinda wish the Angus had the option of a threadless 631 fork, but c'est la vie.

I was split over the Angus and Mark V. I eventually went with the Mark V because of the stem and never looked back. Love my Mark V.

If you use your bike to get *****, you need to work on your game. :p

Angus all the way. I own one and honestly, I think the Mark V's geometry is too similiar to a road bike.

When I was thinking of getting an IRO I could have sworn that the geometry for the Angus and Mark V are the same.

the two have identical geometry

this really comes down to the following:

reynolds vs. 4130
threaded vs. threadless
slightly more expensive vs. slightly cheaper
round tubing vs. ovalized downtube (purely aesthetic)

i like my angus, but i know i would've been happy with a mark v too.

listen to queerpunk if money is a concern

...or drink less beers

Whoaaa now let's not get all crazy here..

Beyond the tubes the choice is really about threadless or threaded headsets. I ride a Mark V because I have tons of extra threadless headset parts (all my bikes are such) and don't like the look of quill stems and/or dealing with threaded headsets. I adore the frame and can't find a single fault with it, I have maybe 2500miles on it.

Ironically enough I'm currently building up a Cross Check....

you've said this before, and others have responded to you.

they are the same geometry.

they are the same geometry.

they are the exact same geometry.

i see your point

but i prefer the geometry of the angus

Hahahaha.

reynolds vs. 4130

Hi, I'm looking into track frames, and IRO frames; and stumbled upon this thread. Was wondering about some difference questions about the IRO frames.

What is the difference with Reynolds 631 and 4130? Is 631 stronger and lighter?

What is the difference with threaded and threadless stem/forks? Sounds like one may be more compatible with some parts or something. What are quilled stems, and what is the opposite of this?


Also adding onto the difference between Mark V and Angus:
Mark V has a hole in the rear bridge for rear brakes
and cable stops on the top tube.

Angus does not. But it's a track bike, who needs rear brakes anyways? :D (maybe for the 1-5% that utilizes the SS)
