Anyone got a sense of minimum rotor size on the rear of an STF?

Hi. I have the STF and had to install a 180mm rotor on the back when I built up the frame. The 160mm rotor I wanted to fit did not reach up high enough for the pads to grab.

Hi all, I'm looking at building either a STR or  STF but have some questions. The plan is to build it with a 120mm Fox 34 rythm fork but also considering a 100mm fork. The idea is to build a bike that will be comfortable enough for the odd 4-6 hr ride but also fun enough for a quick trail session at Wolwespruit or so. 

1. What are the differences other than the sliding dropouts?

2. I am 1.72m would you recommend anything other than a size medium and why? 

3. Is it possible to fit fir a 2.35" tire on a 28mm ID rim in the back?

4. Are QR dropouts available?

5. Anybody looking to sell theirs?????

1. To my knowledge, yes, and the colours.
2. I would go medium, if you really want to just have it as a jump bike, or a nice maneuverable bike, a small, I'm 179 and a large is maybe slightly biggish.
3. I have 28mm and 2.4, so should be good.
4. Unsure 
5. Im looking at switching my STR to a STF, so might sell my frame, does have a few chips and scratches though.

Funny that. I am 1.78m and on a large STR thinking I would like just a couple more mm in the reach department of the bike. This now running a 60mm stem with a 780mm bar and the dropper post has a slight setback too.

I mean, its personal preference and riding style, I like a relatively small bike, so have large, seat almost all the way to the front and 40mm stem

I found that when running a 2.4" Ardent on the STR clearance is a little tight in the rear if I do not get the tyre setup in the largest splay of the chainstays. This is obviously easier to achieve if running gears vs my SS setup.

How about adding a link or 2 on the chain so the sliding dropout can move further back so you have more tyre clearance?

Been there done that. It is at the optimum clearance now. A single link makes a big difference in the fore or aft in the drop outs.....I will come over and show you while you wash my bike.

Sure, bring it over so I can show you how to ride it properly as well

Just to add on this - I've more or less finished my build and I'll post it once I've had a chance to ride it once or twice. 

On sizing it really is down to preference. I'm 1.78 with 79cm inseam - coming from a Pyga OneTwenty (L), that felt like it was a fraction too big, but manageable. So went for a medium STF. Running 780mm bars with a 35mm stem, 150mm dropper and it feels great based on the laps of the driveway I've done while bedding things in. 

One thing to note is the STR can manage 160mm rotors (based on Akwa's set up - the STF has minimum 180mm rotor size for the rear.
