Thanks again everybody., I hope I don't start getting into BMX bikes now! I just discovered that Profile Racing is like two/three miles away, who knew? Here's a little cool info some of you BMX fans will dig.

Follow the PDF on Danscomp (already save the PDF!) Lose my current bearing cups to facilitate sealed bearing set up. which I plan to use, it polished up too nice not to! Stay away from square taper spindles if I plan on using my Profile Imperial sprocket. 19mm spindle, with a 22mm adapter hat since I want to use my Profile sprocket So from what I gather here then, after confirming measurements on the frame, I'll be needing: What I'm playing with here, for additional info, looks to be a 7/8" bore, 44 t, all I have is the sprocket, saw the pin hole and just assumed that I could use it on a one piece crank set if I decided to go that route. Thanks none the less for the information everybody! You'll have tight/loose spots in your chain forevermore.Īh, "Bicycle808" comes in with the answers! No offense to everybody else, just that I knew from another thread he'd messed with a Workman frame and several of the items I'm tossing around. but the only way to run a 3piece sprocket on a OPC is to bore out the hole to 15/16", and if you can't do it perfectly, don't bother trying. Oh, and Baldwooky, you can get 15/16" (aka 23.8mm) to 19mm hat spacers, to run a 1piece type sprocket on a 19mm 3 piece.

on a Worksman INB.Īny other tech questions or if you need links, feel free to ask. I'm running a Profile Flywheel 44t on a 19mm Redline Flite crank. So, which crank? Any 19mm spindle will do 19mm is basically the "standard" bmx 3 piece these days, although there are 20.0mm, 22.0mm, and 7/8" spindles out there, too. If not, Profile sells them, or go with Option E from Porkchop **EDIT** porkchop doesn't have this part if you need to run a 7/8" bore chainwheel on a 19mm spindle, get the part from Profile! **EDiT OVER** **EDIT**April 2017 the url for the 7/8" to 19mm hat spacers is now **EDiT OVER** You'll want to measure carefully before you line everything up, as frequent rebuilding of most BMX cranks leads to the splines wearing down on the spindle.įWIW, a sprocket like the Imperial is not meant for square taper cranks, and won't work on any. If the Imperial has a 7/8" bore, you'll need a 7/8"-to-19mm hat spacer, which likely came with your sprocket. at any rate, don't cheap out! Definitely get a sealed one) and any BMX-style 3 piece crank with a 19mm spindle. In either case, you'll want to get an American BB set for 19mm cranks (You can spring for a Profile or Redline makes a good one for cheap. Depending on the vintage, your Imperial will either have a 7/8" bore or a 19mm bore. If you wanna run a Profile Imperial, I'd STRONGLY advise against going with a euro adaptor you won't need it. Hopefully somebody can shed a little light on this conversion, again this is going on a Workman frame but I think my confusion would translate to other 26" cruiser frames. I browsed the "How To" section but didn't find anything specific and I' know it's been done quite a bit. I get that some of the spindles are square taper or splined for the crank arms, again though, no size references beyond the crank arm? What are the items of concern when going this route (1 to 3 crank conversion)? Obviously BB size is an issue but typically the only measurement I seem to be seeing is the crank arm length. I don't know squat about BMX bikes, which most three piece crank sets I'm seeing are referred to. Now the problem is the sprocket won't fit a one piece crank set (at least none that I have on hand) and hopefully I don't have to go with a Profile crank set up based on the pricing I've seen.
Hopefully "Bicycle808" is reading, apparently done some updating stuff to these INB frames! I'm looking at using a 3 piece crank set on the Workman INB frame, mainly cause I obtained a really nice Profile Imperial 44t sprocket for peanuts (and it's what was used on the Core 77 build that inspired the initial project).
