Surly Ogre? I have one as my utilibike. Have run it fixed, single and 3×9 and whilst I appreciate its lack of front boing, with balloony 2.4s its surprising what you can do.
More relevant perhaps, I went through the ” which HT with suspension”debate and was initially tempted by the fireline. However having followed the thread on here for the last couple of months I plumped for the Solaris as the f’line smacks of a botched rush job whose only real advatage is the metal its made of.
I’ve got the same forks but have taken them down to 100mm which is straightforward enough to do. I gave it its maiden voyage yesterday and its a lovely ride. Will I go to 120mm? Perhaps, but I guess it depends whether you value climbing ability.
Depends on your height too. I’m a shortarse and got the last of the limited run of small solarises.
