Question for Giant Revolt owners

Hi I'm looking to buy a revolt but I have a question about size. My legs are long for my height, so for stack and reach the medium size is perfect but my current fit has a saddle height of 77-78cm. Because the seat tube is so short on the revolt I'm wondering, with that much seat post being exposed, how close I will be to the stock seat post limit? Any medium size Revolt owners who can help me out and check on their bikes? Thanks much appreciated.

Idk if this is feasible for you, but another option would be to size up to a larger frame and size down the stem. I believe with the size medium you're looking at 30-31cm of exposed seatpost. I will check my seatpost to see where that would leave you in terms of min. insertion.

UPDATE: Found my seatpost & tape measure. The post w/o a saddle is ~400mm and the min. insertion is ~91mm. So that's about 309mm of exposed seatpost at your matching saddle height - might be lower once you add the saddle if you took that into your saddle height comparison.

If you want to be on the safe side you can always go with a larger frame and shorten the stem a touch and slam it.

Thanks so much for that, very helpful, I think I could just get away with the medium frame but you might be right that the best option is to size up and then there plenty of room to adjust if its a little long and high. Much obliged sir!

Oooh I can help with that. Happy owner of Giant Revolt (Advanced 0), size medium. I also have annoyingly long legs. I'm 176cm tall and from memory my cycling inseam is around 84cm.

To answer your question, and provide an option you may not be aware of, the shop swapped the stock seatpost for an identical but slightly longer one (+20mm? I forget). The standard one would have been just OK for me but the longer one gives a bit more insertion depth.

I'd be cautious about the idea of "sizing up". I suggest "sizing correct" :-)

In my experience, no off the shelf bike is going to fit us perfectly, it's about getting the best compromise. I rode both the M and the M/L, with input from shop I went medium and am glad I did. After a few months of riding on all sorts of surfaces, I now know M/L would have been too long, although it's hard to make those decisions after a 5-10 mins try out before purchase.

Here's a few numbers for you:
Centre of BB to top of saddle 760mm
Rear of seat tube to top of saddle 285mm (measured parallel to back of seatpost)
Stem length 70mm
Spacers under stem 30mm

After a few rides the M still felt a bit long, so I changed to 70mm x 6deg stem, flipped up to give max rise. It's fine in spite of the people who say it will handle badly, you'll die, etc. And put the max spacers I could fit under the stem. The only thing I would have done differently would be to ask for the steerer to be left say 15mm longer (maybe they come pre-cut, I don't know).
I also tried an Aspero which was crazy low stack, and a Checkpoint which I couldn't fit on at all due the limited seat height adjustment.

Happy to go out to the shed and measure anything else if it helps.
