yes, no problem with that.
>follow up question...

8 speed chains are a bit wider than the 9 speed ones, and are potentially stronger. I've had no problems with my IG51.
>will an 8-speed chain work with my setup (LX '03 cranks)? how much weight will >i gain (i think 8-speed chains are heavier than 9-speed chains, hehe.)?
weight is negligible - for peace of mind i'd go with a heavier, stronger chain that has a lesser chance of snapping under power than a WW one
no such thing as a dumb question...just ask away!

>what's the advantage of using those wing shaped bars on an SS rig? sorry if i >haven't been doing my own research. if there's an existing thread/post, please >point the way.
in general, the wider sweep of these handlebars create a more relaxed riding position - especially if you run a rigid front end - this lets your arms and shoulders absorb the bumps better. the width also helps in giving you more leverage when you need to use your body weight to make it up a climb
>right now the setup on my SS is a standard flatbar with a slight sweep more >designed for XC bikes with bar ends. will this type of setup do? what are the pros >and cons. TIA.
it all boils down to personal preference. there's no rule that you have to use swept bars, flat bars with bar ends, or even riser bars with bar ends. the important thing is the setup has to work for you, your style of riding, etc. I've since flipped my Mary bars, because it helps me "get in between the wheels" - I guess the best way to describe it is that my weight is lower (and not forward), than when it was right side up. it took me a lot of trial and error to find a position i was comfortable in for the majority of the riding that i do

thanks for answering my questions 32by18. i was thinking of changing my gear ratio kasi whenever im at the trails. right now its 32X18 but i find it a bit harsh at times especially if were talking about the trails in maarat where the gain in elevation is really something to be scared of when you're talking about SS. im thinking of going for 32X20 on offroad but for regular urban stuff, 32X14 should do, i think.

Go for it Maybe you can set up 2 different sets of rear wheels and chains and just swap them out when necessary?

yes every time to use the chain tool it weakens it. but if you want to have two different gear ratios for your bike, a spare wheelset is a solution.
you can also run a dual chainring/dual rear cog set up, with different ratios for each. You just have to calculate the ratios that will require the exact amount of chain, but yield different gearing. A bit of math work but some people (in the States) have done it.

But then it won't be an SS anymore.

Its still an SS Bruce as long as theres no RD or FD. Just like a flipable old school bmx wheelset ;D
How about this guys, I was thinking of making an SS with an RD (?) shifting between a fakie gearing (spacer so that the cranks doesn't engage or backpedal) and a rear chainring. Any ideas how do I approach this?

Any ideas how do I approach this? I'm assuming you will be running a fixed gear system? If so then the your spacers have to be the same (teeth/outside) diameter as the rear sprocket you are using to allow the chain to disengage and re-engage as needed, tuning the RD will be the easy part, ensuring the chain does not go bonkers in another, I'm guessing you want a neutral + drive setting on your SS that is not similar to coasting freewheels. Man this is gonna require some machining! but I think it is doable.

Peeps,
I'm planning to setup a single speed bike. Is it okay to install a 1.25 tire and a rigid fork? By the way, my planned gearing will be 36T front and 16T rear.
Salamat...

If you plan to ride roads most of the time, that would make a sensible set up! If you plan to do a little trail riding, just switch to 1.95 knobbies for better traction. 36 x 16 is a good gear ration, not so tough on the climbs and you can power through the flats with minimal over spinning. ;D

@ungas...thanks sir got lucky with the choice of gearing...38x19 went in with little trouble. lloyd the gearing is a good choice the wheel size howeve even for paved roads, the size may still get through road cracks and grates easily and you know what that results to, I use 1.75 nimbus which are good for metro manila lubak!

I don't mind walking (biketaineering along w/ my bike during the uphill. But once goin' down... the ride is sweet... I'm a convert now... Thanks... Sorry for the pics... wala pa eh...

Sir Jack,
Thanks... had tried to bomb down the rig on small drops... 3 to 4 feet to tranny... its smooth... no clang... clang noise made by the chain and the chain stay during landing. I really love it.
Again thanks...

jacklero-- saw your post of the Look roadbike, indeed minimalist, it will be fast on the road... very good for chasing and overtaking jeepneys, garbage trucks (specially when they stink!), and taxis hehe
I think it can also handle mild XC, except probably on steep and continuous uphill, it's too tough on the legs you can't help but to stand and give all your effort. But as it goes, it's not about the bike, it's about the biker hehe

lloyd, i suggest you put the tensioner in the "push up" position, with the roler pushing the chain up towards the chainstay. the chain will be tighter and will not come off the cog even on the rough stuff.

Nice bike lloyd!!!! Yup I agree with king use the tensioner in push-up mode, this gives the chain more teeth to engage, you may need to shorten the chain a bit though as push up mode requires your chain to be the shortest number of links possible with your axel fully seated. then just use the tensioner to create the necessary chain tension without binding, the chain pull/action should also be smoother most specially if you run a single-speed specific cog.
PS. is that the single speed kit from sir ben?

Sirs, Had installed before the tensioner in a push-up position but the chain has a sag. So I, change it to the opposite direction - push down position. The chain is tight. Had tested it on very rough descends and its okay. Had bomb down the rig at least on a 5ft drop to tranny and 5 ft big air... the drive train had stand up to the beatings. No clang2x noise . So far, the chain hadn't come off. Thanks for your inputs. I'll again try installing the tension in a push-up position. Sir Jack, Yap, had bought the crankset from Sir Ben. For the Da bomb 9 to 1 converter & tensioner, had bought it here in the Cebu (Aison & YKK).

hitebeer - your cannondale has now been Single Speedified!!! Will post pics soon.... Got the WMI SS kit from sir Bee last night and all I could say is "PERFECT CHAINLINE" yeah baby yeah...I now have two bikes running tensioner-less setups on vertical dropouts....swerti!!!
