|I've converted my mtb to a single spd cross-type bike but I'm having a hard time with the fit using drop bars. My TT length is 23.75 C-C (long) and my stem is about 90mm (about 5 degree drop). I feel way too far forward and a little out of control. It's been a loooooong time since I tried using drop bars so it could be me. I'm thinking of going with a short 60mm stem that would have a rise of about 10 degrees. I'd like to hear some other bike set-ups and have a sanity check if my proposed setup sounds way off. thanx.|

I, too, had a similar problem a couple years ago when I converted a older mtn bike to a ss cx bike. I found that using a higher rise stem and a drop bar with shallower drops and a shorter reach (WTB Off Road drops work great for this) allowed me to ride the drops most of the time with lots of control. I have recently picked up a used CX frame/fork and converted it to SS. And had to convert to a road-type stem and also changed to some CX bars. My bars are a little lower now and the reach longer, but still acceptable. I've gradually changed my riding position and adapted to the new cockpit. So a very good pair of WTB drops are available (only about 6 months use) and a new stem (110 x +40 - I believe). Let me know if your interested. Will post in Makret soon.
The stem you mentioned (60 x +10) may work out very well for you. I will certainly sit you more upright and provide better control than the current setup.

|My mtb TT is 61.6 and stem 13. ideal for me.
I had a CX frame built custom, 60.0cm TT and I got a 10cm stem. Perfect as well.
Both stems negative rise (drop?)
That's a total of 4.6cm shorter cockpitlength!
Depending on the bend of your drop bars, you'll need a seriously shorter stem for sure. Try moving the seat forward, see if you can handle the steeper riding position, along with the 6cm stem that might be enough. Also, did you turn the bars to have the levers point up a bit? That makes quite some difference.
I hope the short stem (Fisher's Genesis geometry - in Cross???) will work for you, also while riding.

|It sort of depends on your size. I did the math in my head so sorry if I'm off. That works out to be about 60cm. That's a pretty big T/T. Heck I'm not a racer so my set up may be conservative but my T/T is around 55cm with a 12cm stem so that's 67cm over all, I could probably go with a 13cm stem like my road bike but the 12cm is fine. I'm 5'9" and my torso is a little shorter than from the waist down.|| |
