Hi,

I ride a 29, supposedly Medium size frame, and my current fork's steerer tube from crown to top is 190mm approximately.

I will change the fork soon. The fork I am buying has a 220mm steerer tube length. I want to know these:

• What is the recommended steerer tube length? Should I cut mine to 200mm or something? I tried to simulate a 20mm increase in height of the handlebar and it seems it does not make much difference.
• Is it true that is it recommended to not use more than 30mm spacers between the stem and top headtube? If yes, does this mean, from this, I can guess the correct steerer tube length by placing 30mm spacers under the stem plus the stem and cap and cut the excess?
• What is your steerer tube length, assume you ride a 29 bike?

Thanks
