I need some suggestions for a crankset for my Schwinn Homegrown that will soon be my singlespeed. They will need to work with an American Classic ISIS bottom bracket. Any help would be greatly appreciated.

Any ISIS compatible crank should do. The only limitation would be the BB spindle lenght, I'm assuming you already have the BB, but, then again, if you use a "converted" hub you can adjust your chainline if needed.

Right now, it seems like most ISIS cranks available are abuse oriented cranks (Truvativ Hussefelt and the likes) they may be overkill for you, but they should work. I guess the big Q here is: How much do you want to spend on the cranks?

Hmmmm, someone else with a Homegrown SS. They make nice SS bikes, light, stiff and responsive. I wish Schwinn still made these bikes.

You can get a Truvativ fairly cheaply. I've got the bontrager/truvativ crank on my 29er SS, works well. More importantly, pick a good chainring.

I hate to admit that I don't know enough about the world of singlespeeding yet, but it's true. :rolleyes: As far as cost goes, I'm not really sure. I'm willing to spend a little more if the equipment is worth the cost. Also, as silly as it may sound, I'd like the crank to be black. I have this weird thing with black bikes. Is there a good online spot to buy the cranks and chainring? I don't know if I should be looking for something singlespeed-specific or not.

I've had good luck with bikeman.com. They have a single speed section on their site that makes it easy to find SS stuff without having to look at all the geared stuff too.

I will be upgrading out of ISIS and into outboard bearing in a few days. I have Truvative Stylo team cranks (ISIS) in black that are a year old and will let them go on the cheap. They are a great crank. PM me if you are interested.

Pricepoint has the FSA V-Drive Extreme cranks arms for $35 right now. Not the prettiest, but hell for stout. Get that, a Blackspire SS ring for $25, some chainring bolts and your in business with a great crankset for about half of what most "SS" cranksets cost. If you really want to give it that special touch, get the RaceFace bashguard for $27. These are bulletproof and most importantly, really look cool. You will not get a better ISIS crankset no matter how much more you spend.

I'm running a 32x16 on my homegrown, but that's not a magic ratio. I'd like to know what the magic ratio is for a homegrown. But until then, the tensioner stays on the bike. I think there is a formula to calc the magic ratio, but I don't know it. But somebody out there does.

I can recomend these also. We trials riders use them and they last a long time.

I've recently discovered on my 17.5" "Homergroan":D that a 32x16 with a half link is magical. Until I put the half link in the 32x16 needed a tensioner. Little slack but it has not come off in some rough rocky singletrack I've ridden. As said a 32x17 with a half link might be better, a little less slack.

i'd love to get an ENO hub for my homegrown, but i wasnt sure i'd like single speeding, so i couldnt justify buying one and building up a wheel. my homegrown is getting a new surly stainless cog and surly chainring followed by a new bottom bracket. i'm running a kona ridig fork on it and it's pretty sweet for now.

To find the best gear ratio to fit your chain, just Google "chain length calculator" or something similar. There are a bunch of different calculators out there.and all you need to know is your chain stay length (bottom bracket to rear axle c-c measurement). Some calculators will even give you ratios depending on whether you want to use a half link or not. I used one to find that a 34 x 20 fits my 19 inch Homegrown just fine.

Also, while I know that the original post requested information on ISIS compatible cranks, I feel I should put a plug in for external BB cranks for use with a Homegrown. I think that the extra stiffness found in an external BB crankset helps offset some of the lateral flexiness of the lightweight Homegrown frame. The cost is not too bad either if you look for a sale on Shimano LX model.

Bensbike on eBay has or at least had "New" 2000 Homegrown Pro frames for $199.I don't see any listed on his site but I'm thinking if you call they can hook you up. You will need an ICBM headset which they also carry as a OEM item. I've purchased several for my son as he grows. His first one, a 12" Homegrown was built up with XT / X-9 components and with AC wheels it came in around 18lbs. I'm just about finished with his new rig which is a 15" Homegrown decked out with SRAM XO and should come in about the same. Excellent frame but comes with 20mm disc mount. I run the Avid Ultimates V's on his which works great since he weighs about a buck.
