Converting my multi-geared mall bike to SS...
If I understand correctly, with cassette hubs I will only need spacers to align the freewheel with the chainring for a perfect chainline.
I have a threaded hub which I intend to fit with a BMX freewheel. Is dishing my only option to perfect my chainline? Wouldn't this be too tedious each time my wheel goes out of true?

you can also make adjustments at the cranks. your mechanic will know what to do.

A threaded hub is also a track hub..right?
Adjust on the cranks for proper chainline, maybe change BB's if cranks cant align to proper width.

Thanks bros. Will look into both--wheel true and crankset area for alignment and fine-tuning.
Been going around Quiapo looking for SS specific crankset. All I can find are 40T and 44T non-changeable cranksets. Where did you guys find 32T cranksets? For the freewheel, all I found were 16T and 18T so combining this with 40T chainring might require heavy pedalling. BTW, I ride mostly flat roads (typical Paranaque subdivisions). Would 40x18 be alright for a beginning SSer?

Hi, dishing per se will not help in chain alignment. Dishing means offsetting the rim relative to the center of the hub to compensate for a sprocket or disc brakes. What might help is disassembling the axle and shuffling the spacers to get the right chainline and then have the wheel re-aligned(or re-dished to center the rim on the frame. too much work ata Better do what the other guys said na lang and work from the BB.

the 32T cranks are conversions of regular mtb cranks w/ the large & small rings taken out. if all you're using it for is the subdivision a 40 or 44 is fine. even 53 is fine if it's all flat.

Thanks sir mcvarki. Hehe, you're right, by dishing the only thing that will move will be the rims since the hubs are fixed to the frame. I got a bit confused there. ;D About the spacers... what type of spacers do I need? Do I also need to buy spacers for the threaded part or do you mean these extra bolts I see on the axle (are those there for spacing)? the 32T cranks are conversions of regular mtb cranks w/ the large & small rings taken out. if all you're using it for is the subdivision a 40 or 44 is fine. even 53 is fine if it's all flat. Thanks sir king. I might get the 40T then. However, the lightest sprocket I found so far is an 18T one. Does anyone think this is a bit heavy for a beginner on flats (typical P'que subdivisions)? How about the 16T? Thanks again.

i have 42x18 on my road bike and i use it everywhere- commuting, climbing and long rides. 40x18 is fine for flats. even 16 will do. besides even if it seems heavy at the beginning, you'll soon get used to it.
