    Cross Check crank/gearing

    I'm planning on building up a singlespeed cross check as my do it all rig; commuting, singletrack, road, etc. I was wondering what would be a good crank for me to use and how should I gear it. I would really love to hear how you guys ride your cross checks and how you have them set up.
    Thanks

    On the road a 42T ring works well for most. It is pretty unusual to ride road and singletrack efficiently in the same gear. I'd keep a 34 or 36 T on hand to switch to for true trail riding. Just have two masterlink chains on hand sized and ready to go for the switch and you may or may not have to adjust your brake pads with the switch. I like an old school 110 BCD square taper crank like Sugino's XD 700.

    Yeah, old suginos nice, even the new ones are fine... I have old ritcheys on mine, verry low profile and made by sugino IIRC

    It's not my Crosscheck, but I have an old Diamondback Apex I use mostly for commuting and maybe a little easy trail on the commute. I bring it up because I use it in the same way you describe. With 2" tires I run 42x18 gearing, which works out to about 61 gear inches. It's a nice pavement gear as long as I am not in a huge rush; about 15mph is easy to maintain and maybe maintain 18mph if I want to spin a little. I did one single speed race on it over a fast trail with some short, steep climbs. Anything resembling steep I had to walk.

    If you go with a smaller tire (like 30mm) 42x18 would give about the same gear inch. At least for around here (southeast Michigan...we actually have some hills here despite what you may think) and my fitness, which is not too bad, this is a good comprimise gear for doing everything. It's not perfect but it's fairly versatile.

    I use a square taper Shimano Sora road crank I had laying around. 42t rings are easy to find in the 130 BCD road size since that is one of the "standard" road ring sizes.

    I ride 44x17 with 37c slicks on roads. Great gear for flats and slight up and down hills. True climbs are squat workouts and if treated as such go rather well in my nutty experience. On trails I plan on running a bit and go to 38x17 or 38x18. I ride road about 95% of the time.

    I currently run Sugino RD cranks with the stock 48t ring up front and just purchased a white industries Dos Eno two speed freewheel in the 19/17 flavor. I currently run an ACS 20t in the rear and finally decided it was too easy. The plan is to move to a 44t ring up front and run the 17 in the back , and have the 19 in reserve just in case. I'll post a followup when its done.

    Also, I was planning on putting a track cog on the other side of the hub. How should the track cog compare to the freewheel as far as size?
