Don’t forget that another difference between 54-56&58cm frames will have different crank lengths. At 5’11” I would imagine you’d be between a 56 and 58, no? Unless you want a long stem with a low position.

I'm taller than the OP and I would strongly suggest that he not get a 58cm, IMHO that's too large.
I suggest 56cm for the regular rider or 54 for someone that likes to be fairly slammed or low.
According to this sizing chart, 56 is considered ideal and not between sizes for the OP.

1. He just wanted to know what other riders with a similar height are riding.
2. He wanted to know if a smaller or bigger frame would be better (54 or 56). IMO like others said as well, a smaller frame is superiour (providing you don‘t need a lot of spacers). A bigger frame makes you feel like a passenger and not a rider.
3. a 58 frame would be definitely too big.
4. A sizing chart according to height is pretty useless. (like I already mentioned in my first post, there are a lot more factors to factor into)
5. calm down. It‘s just cycling, and there are obviously different opinions, like in every topic on here.

of course it‘s contradictory, but he can still ask for that even tough it‘s useless... You are stating the obvious...

I am 178 cm, 5 10 with longish legs (BB to saddle centre 755 mm). I looked at buying a Tarmac to find that the 56 was a bit too long and the 54 a bit too small (stack) without loads of spacers. I only have 80mm of drop.

There is a big difference in reach between the two sizes, 17mm once corrected to position the stem at the same height on both bikes. It's a common mistake not to make this correction. Subtract 3mm for each 10mm of stack height difference, from the reach of the smaller frame, to get the proper comparision.

The Tarmac has a bog-standard fit at those sizes so either use a combinations of spacers, flip up a 6deg stem on a 54cm while dealing with the aesthetics, or use a shorter stem on a 56cm. Or just get an endurance bike...nothing wrong with that.

Also consider using something like Aerofly riser bars for +25mm in stack height.

Thanks Tobin. Rode both the 54 and 56 over the weekend. Wow! Agree there is a big difference between the two and if there was a 55 it would be a perfect fit! I already have a C60 so am actually steering toward the endurance bike for all year round and then relooking at the tarmac when the new one comes out later this year

It might be obvious to you but it's not obvious to everyone. The OP asked for sizing advice on the basis of his height alone - why do you think it's a bad thing to tell him that sizing advice based purely on height is useless, given that you agree with that advice and hav stated it yourself?

What stick? I haven't said anything insulting or confrontational, it's you and the OP that are getting shitty and personal. Chill out, you'll feel better.
