SG75 or SG75DD

People on here have their own opinion and they just shared to you, seems like you'll endup with rotors go with it ;) and thanks us later

@AlphaOmega just evaluating. To be completely honest with you I think the look of the Sugino fit the frame way better. Especially outside of the track and without a proper aero shape the bicycle looks better with an open crank. However the more modern shape of the Rotor crank arms as opposed to the dated Sugino ones is quite appealing. Even when I was looking at the Miche Pistard originally I was more inclined towards the 2.0 rather than the Air, but then I read of all the misfortune with Miche in general and I binned the idea of getting them; they are cheap and for a reason I suppose.

Uhhmmm uhmm yeah the rotors looks good but some people on here had a bad experience if you still cant decide go with miche, otherwise dds ftw

No no, after seeins photos of badly snapped Miche on here and the overal reviews and sentiment about them I'd rather stay clear.

I'm fairly sold on the SG75 DD at the moment. Now, if only the shop could come back to me with a quote for all the components, that would be nice as well :-)

Or omniums

Nope, I dont' like them, I checked pictures online and it doesn't convince me on this frame.

function>form

True, but why not both? The SG75 will give me that.

I ran a Miche Primato Advanced crankset with no issues for about five years on my commuter...

SG75 with square taper BB last for ages. I've had the same loose ball Hatta BB in mine for three years with about two services and its still smooth as.

Those Rinpoch cranks look cheap. The back side of the crank arm is minging!

One issue I remember now having with my DD is that the Q factor is so low I had to adjust my cleats, so now those shoes aren't good on the other bikes unless I change them each time I hop on another bike. Shoes++.

I was actually lookign at the Pistard 2.0 or Air. Although I remember of people on here talking about snapping the primato quite easily, this link is the only I found. By the look of it they don't seem very fit and go and by the time they are good I basically spent the money of a Sugino which so far seems to have a better following and praise. Don't get me wrong, as usual mileage may vary but I think I'll stay on the side of caution and follow the masses.

That's perfectly fine, I'll have only one ride when the project is completed.

Is it lower than on regular 75s?

I've have/had rotor, Rinpoch, dds and 75s. Go with dds (my 2p). Rotors, (unless they are the pre 2015 garish model) cant really handle everyday skids. I'd still be running dds on my parallax if I didn't have Rinpoch. Rinpoch is pretty good, the bb is decent and the chainrings are pretty well made. DD's As ellis said, switch out the bb for the ultegra and you're good. I still use the original "crank bolt" just covered with some black tape. It no longer comes loose, it has been around 8 months.

I snapped a pair of Miche Primatos, but, in all honesty, I was a total twat on them. I managed to completely fuck up the square taper interface on the non-drive side crank arm, and snap the arm shortly after, all in one day of city riding. (I'd ridden hard on them previously, and this obviously contributed). To be entirely honest, they seem fine on 99% of bikes that they go onto, and im sure that they're okay, but, after my experience, they scare me, if anything.

When you say DDs I assume you mean SG75 DD right. For Rotor they would be the new ones and I could be good with them, I'm not planning to be a hardcore skidder or anything.
So from your answer I take that your opinion is Rinpoch > Sugino > Rotor?

See that's the thing, I know myself and my luck, I will very much likely end up in that 1% instead :-)

Yeah, I wouldn't recommend them for riding fixed. What scares me about Primatos is not that I snapped them, it's that I managed to strip the square taper, and badly. That square ended up looking like a squircle - and that was just from skidding about on them for 2 months. Single speed, I'm sure they're fine

Primatos seem to be made of an only slightly sturdier type of cheese than miche lock rings are made of.

We get a lot of them bending in crashes, from the bike landing, heavily, on its side.

Infact I ruled them out straight away, I'm sure that Sugino, Rotor or others might have failed in the past for people and still fail too, but I read way more complains for Miche than for the latters.

@M_V when you say we I assume you work in a shop right? What's your take on Sugino vs Rotor assuming you might have direct experience?

I take it you work in a bike shop, and, to be honest, I've realised that you can never trust ideas formed by people who come into your shop, because I see some things at work which are genuinely atrocious, and are not even worth forming an opinion on.

Last week, I came across quick release crank arms. QUICK. RELEASE. FUCKING. CRANK. ARMS.

@debo those of us who do are professional mechanics don't necessarily have experience... we are more just scarred from the strange things we have seen

Work at a velodrome, we have 79 bikes with Primatos so quite experienced with them, the others not so much.

Personally though, the spider/arm interface on the Rotors looks like a weak point. I have experience of other cranks that use similar systems (like middleburn) and wouldn't recommend them for fixed use outside of a velodrome.

I agree, it does seem like a weak point, but it seems like the garish old Rotors hold up fine to everyday use, whereas the newer ones don't. Do you know anything about how the system has changed, and the differences between the spider designs that makes one durable, and one total cheese?

I'm afraid I don't.

Manufacturing tolerances would need to be pretty tight to eliminate any chance of play developing, maybe they've slipped recently?

@M_V @ShutUpBlud thanks for the inputs; even taken with pinch of salts because, individuals opinions, still they make me inclined to think the Sugino might still be the best call out of the lot.
