|ok, so i am going to show my ignorance with these questions but oh well....i have an old mtb frame that i have been using as a single speed conversion but i just purchased a single speed specific bike so now i've got 2 single speeds, a road bike, and a geared mtb- that isn't going to be allowed in my garage if i have 2 of the same kind of bike so now is the time to try cross. i've been interested in the cross bikes and wondered if i could just use my old mtb frame for cross to try it out. what things do i need to do to convert it to cross, if possible?
what is a good gearing-road or mtb cranks(standard or compact),
cassette-road or mtb,
can i use v brakes,
i've seen people use flat bars- is that normal,
can i use mtb shifters if i go with a flat bar,
front and rear mechs,
would i use a standard 700cc road wheelset- would that even fit in my mtb frame,
i've currently got a manitou mars fork on front and i think that will need to go to rigid, i've got a threaded rigid but would rather go threadless, any recommendations for 1 1/8 threadless steer tube forks that would work,
thanks for your help.

|Any rigid fork will do. Get the Ultech brake adapters to make the 700c wheels fit. I posted details about those on this board before, find the reply with pic. These things work great for mtb-cross conversions!|

|I could not find your reply about these Ultech brake adapters, could you give some more information? Are they for using 700C wheels on a frame designed for 26" wheels? Thanks for the info.

|1. 36x48 chainrings. Either crank is fine. (36 may limit you to a mtb crank only dependent upon bolt circle)
2. Most use mtb because of bigger cog availibility. ~ 13x34
3. yes. If you use road type brake levers, will need an adaptor of some type (any LBS) as road levers will not actuate V's fully. Canti's work better on a cross bike.
4. normal, no. most use road bars.
6. dependent upon what type shifters you use. Also note that many 'cross bikes use top pull front D's. Road bikes are bottom pull, therefore many crossers use mtb front d's.
7. On a 'cross bike, yes 700's. On a mountain bike used for cross,
no. 700's won't fit mtb frame w/o hassle (mainly due to brake surface/brake pad differences)

|Ok then, once again the pic and link for this handy brakeflex kit.
This is the very cheapest way to get yourself a 700c terrain bike to get the feeling. You just need these babies and a pair of wheels.
