Thanks King, will call up Edmund. Maybe he knows where I could get one with a 20T, if none maybe an 18T would do. Will walk uphills na lang. ;D ;D ;D thanks again, Alain ;D ;D

hi Alain Sorry for the late reply, I don't have a proper picture of my bike (full-on side view), but I will snap a photo soon and post it. The Da Bomb converter kits usually come with an 18T cog, spacers and tensioner. You can look for a slightly used 7 or 8-speed cog, and disassemble it. Make sure the cog teeth are in good shape, and keep the spacers (and the other cogs too..if you want to experiment)... Your frame MIGHT be able to run without a chain tensioner, but that depends on your choice of gear ratio (chambahan lang), or use this online tool to look for possible "magic gear ratios": www.peak.org/~fixin/personal/fmu/php/tutorial.phpFor more SS info, click here: sheldonbrown.com/singlespeed.htmlhope this helps!

there's only one gear if you mean can you change the cog, yes. can you change the gears in the 9:1 converter? or not?

how can much do i have to pay for a chain tensioner? is it possible to use an old RD? I have used an old RD as a tensioner, but I prefer no tensioner. I know this is difficult on a converted frame, but if you have semi-vertical dropouts combined with a half-link and the right gear ratio, it's possible. My old setup was using a cog from an XT cassette and PVC spacers. My new setup is using a shimano steel cog (i'll post photos soon). when using a RD, make sure tension is as tight as possible. I fabricated some spacers using my dremel tool. I can add or remove the spacers for additional chain adjustment for wear. Here's a closeup of my current set up with shimano cog with tall teeth that are difficult to derail, PVC spacers and no tensioner. take note of the half-link. As you can see... I'm experimenting with a "2 gear" SS. 36:20 for trail riding and 42:13 for street riding. Both ratios happen to use the nearly the exact same chain length, all I do is loosen the quick release for street commuting.

i think i heard the frame saying " ouch!!! man can you put that clamp somewhere else?" Point taken mato. I really should mount the clamp to the seatpost. I've heard of people crushing their frames with the Park workstands, esp since their clamp mechanism is very unforgiving. The Ultimate stand's clamp is not so burly and is difficult to overtighten. If the frame were carbon instead of Ti definitely a no-no.

32x18... I like those rigids you posted. esp the one with the hydro rim brakes. I gotta get a set of those.

Thanks to all you guys who posted their bike pix, these are the looks that (exactly-mismo) I had in mind. Rigid SS. WOW!!! ;D ;D ;D 32X12, I hope you don't mind me copying the color of your bike. Very nice indeed. ;D ;D ;D. Yours too cbomber. Wcoastbo, DS(double speed-is there such a term?) inteads of SS.HMMMM. Seems like a great idea, but I think i'll go for SS first. Nice bike you got there too. Thanks again, Alain

cherrybomber- my frame is a budget/generic Ti built by Sandvik/TST, I believe. don't quote me because it was purchased as a Supergo house brand frame and any mfg could have made it for them. Mine is older than this current batch being sold... www.cambriabike.com/shopexd.asp?id=19150I'm really sold on generic Ti and my frame has held up well over the years. It won't rust and when I scratch it... steel wool will fix. There must be a taiwanese supplier of Ti frames. Is your habanero also Ti? Alain- I will be removing the "2 speed" soon to keep it a true SS. My experiment was successfull and I'll be applying the derailleurless concept to a rigid commuter/mtb.

bo: neat setup with the 2x2 (or is it double SS). The Magura hydros I am using have been bombproof so far...just a few pad changes. They deserve to be bled though, as I think they are still running on their original fluid! alain: sure, build your baby up, and let's hit the trails! cherryb: ss da hab. ss da hab. hehehe king: convert your GF (gary fisher, not girlfriend!), the carbon one. may crack na din, so might as well ride the hell out of it

newbie question, i've always wondered:
if i use a standard mtb hub. where can i get cogs to go SS?
i'm only familiar with the threaded type like those used in BMX.

you can use an old 7 or 8 speed cassette. Just let the bike shop dismantle it. Salvage the spacers from the cassette too, so you can fine-tune your chainline. The DaBomb converter kit comes with a cog, spacers and tensioner as well, but the spacers don't allow for precise adjustments. You can fashion spacers out of PVC pipes, just make sure they're cut perfectly straight. If you have more questions, ask away!

haha i'm riding the hell out of it anyway. i'm waiting for more news on the la mesa race. that's more managable on SS then the one in ormoc. haba ng climb sa ormoc! if i convert for la mesa using my existing parts, that would be 34x16. by the way, i really like my 42x16. it's not too light on flats and not to heavy on climbs (well, just flyovers so far. doing antipolo soon). bo: neat setup with the 2x2 (or is it double SS). The Magura hydros I am using have been bombproof so far...just a few pad changes.

yep my hab is ti- i guess its a step above generic really but nice and solid. famous for its lack of flex where it counts which is important for clydes like me oh they also do custom builds for a grand USD. not bad ey?

newbie question, i've always wondered: if i use a standard mtb hub. where can i get cogs to go SS? i'm only familiar with the threaded type like those used in BMX. These are the shimano cogs that I use. BMX type with tall teeth, not designed to shift and won't derail unexpectedly on the trail. They fit on shimano mtb hubs... store.airbomb.com/items.asp?CartId={E7F7616C-EVEREST2518-4562-985D-9E97C802EF10}&Cc=706%2DT%2D367&iTpStatus=1&Tp=I'm putting in an order for a 16T. Does anyone else need one? I'll be in Phils in two weeks and will deliver by hand in exchange for a guided tour of the local trails near Pinas. They have 14T, 15T, 16T and 18T available.
