The Nexus and Alfine hubs are 130 mm axels which is the width for road dropouts. Mountain bikes are 135 mm so you'll need spacers if you want that. Track bikes and BMX are normally 120 mm so that's out unless you want to cold set (i.e. bend) your dropouts out to fit (only do this with steel frames). Cannondale's site does not specifically tell you the drop out width, but based on the hub selection and the fact that it's called a track frame, I'd say it's probably 120 mm. It looks to be an aluminum frame which I would not get into bending as that will potentially structurally ruin the frame. The other issue is what kind of dropouts you have. Most bikes these days have vertical dropouts meaning the wheel's position relative to the rear triangle remains the same. With a single speed, you need horizontal dropouts or a chain tensioner to get your chain properly tensioned. This would not be an issue for the Capo as it has horizontal dropouts. Chris,

I've been desperately trying to figure out whether an Alfine will fit into a 2009 Cannondale Capo - a singlespeed as stock. But you mentioned that they will fit in most roadbikes - and though it may seem like only a tiny bit of info - it's the most I've gotten so far on the matter! I'm thinking about getting the Capo and putting an Alfine in the rear, and maybe trying to squeeze on the Nexus grip-shifter for simplicity's sake. Any thoughts? Cheers dude Hi Elliot – very helpful.

I spec my bikes with 48T on the chain ring and 21T on the rear which seems to be enough for the hills in our parts as well as giving me a decent speed on the flats. Dynamic uses a 46T/19T combo. This yields a range similar to a compact crank on a road bike. Bernie,

I wonder if you would be able to help me or anbody else! I have a Cannondale Bad Boy 8 Ultra 2009, with Alfine 8 speed hub. Although I like the bike and the Alfine hub I do think the bike is under geared. I have a 18T cog on the back and a 42T on the front. I find the gearing ratio in 5 and 6 not quite right when going up medium hills, also i find that I’m lacking speed in top gear and i feel i need one more gear. I would like your advice as i am thinking upgrading my front chaining/ small cog for more speed and a better midrange (5 and 6)between the gears. I was thinking to upgrade the smaller cog to a 16T and a larger chainring either 48t 0r 50T . I'm keen to customized my badboy ultra to a very fast road/ touring bike for long cycles at the weekend. I am a stronge cyclist ( i cycle 110 miles a week to work) and live were there are some very good steep hills in which i can cope in in low gears 1-4 as the alfine hub gears are very close togther in gears 1-5. My bike setup is: A 18T rear cog and front crank is a Truvative Fire Ring 42T, my – wheels are DT Champion 700 with continental sport contact 28-622 tires, whith Avid Juicy 3 brakeset front & rear I would much appreciate any suggestions and recommendation. Thank you Hi sir

Some bikes come like that, like my recumbent Bike-E -- it has a 3 speed internal hub with a rear deraileur. You'd still need a chain tensioner, however.

Is it possible to use a triple crankset and a front derailleur with a rear internal gear hub? I have a hilly commute and think I need more than 8 gears. How tight must the chain tension be? Thanks for your help, but don't laugh too loud if I am missing the obvious. I might have a very dumb question, but here goes.
