Marc do you have any suggestions for seating the bead on a tire? The front is being stubborn.

i'm guessing that it is a tight fit? there is only really one way. pump it up until it pops into place. if you get to 100psi and it hasn't popped yet, let the tyre back down to about 15psi, try and pop it out a bit by hand (to do this you have the bit that isn't sitting in place facing towards you then grip the tyre and try to roll it off the other side of the rim) then pump it back up again.

i am only using 100psi as a guide as it depends on what the max reccommended pressure of the tyre is. if the max pressure is only 60psi then you wouldn't want to go much past about 80psi. however if the max pressure is 90psi then you can go to about 130psi (although it will usually pop out about 110psi).

you can also try wiping a few small amount of washing up liquid around the bead of the tyre before pumping it up this will make it a little bit more slippery and pop into place better when it is pumped up

Just got my first road bike on the weekend for $100

The brand is Xtreme and it's pretty much new

popped both tires on the first day cause the outer said 100psi

and the inner probably couldn't take anything over 80

gonna be hitting the Centennial Park tracks every weekend

to see if I'm fit enough to do the Syd-Gong MS ride :P

pretty sweet hog for the price... dunno if i'd do sydney to gong on it myself though!!!

marc - what's your take on "slimes" i got a pair the other day and i'm very unimpressed with them =( only fitted one, not happy at all so returning the other today and swapping for just a regular tube.

i'm glad you onlt paid $100 for it, cause i certainly wouldn't have paid anything more for it. that isn't entry level. an entry level road bike is worth about 5 times what that is. probably the cheapest, nastiest road bike on the market (since it is a supermarket bike), and that's why you would've popped the tubes. the tubes should take higher pressure than most tyres. they tyres are what determines the pressure. tyres with weak sidewalls won't take much over about 90 to 100 psi (when rated to 60psi) before they tear the sidewall apart. a tyre rated to 100psi will take up to about 140psi before it starts to tear. also cheaper tyres punture much more easily due to lower density casing. and they are heavier.

just have a look and see where the punctures occur. often on those cheap bikes it will be on the inside because they have used a thin rubber rim stip and the tube buldges into the spoke holes and creates a thin spot which then pops.

personally i think that any road bike that doesn't have intergrated shifters (shifters in the brake levers) is a waste of time. that bike would be much heavier than any other road bike, and more than likely be much more uncomfortable to ride as well as a rougher ride. you would've been better off paying another couple of hundred and and gotten something a bit older but much better quality. if you plan on doing long rides expect to be having to replace the wheels in a few months after the hubs shit themselves. also if it is a 6 speed (can't tell from the pic) and the freewheel isn't a shimano one, immediately take it to a bike shop and get them to fit a shimano one. it will save you being 20km from home and have the freewheel pack it in and leave you without any drive (you will pedal but the wheel won't turn).

sorry to rain on your parade, LOL

rowan, not a big fan of slime tubes. they often don't seal the hole up until they have let most of the air out of the tube, and after a while they just don't seal it up at all.

yeah nah got rid of the slime tube - the shop let me swap it over for a hutchison one...

and yeah - that bike will be suitable for riding to the shops and such, but for actually riding long distances ie syd/gong... no... if you can do it then that will be awesome

infact

i'll fedex you a can of coke!

you will only get road tubes with presta valve (french valve). yes there is an adapter to make them a car valve. they should only cost a dollar or 2. they are a brass adapter that screws on.

as for good tubes, pretty much any tube will do. with those tyres, don't go for any lightweight tubes. go for somthing like CST, innova, maxxis, tioga, etc. basically any brand from a bike shop ecxept swallow. they are shit tubes, LOL. something like the michelin airstop butyl are a good tube. not too thin and made of better quality rubber.

they aren't a bad tyre. and at that price you can't go wrong. unless you do lots of kms on dodgy roads. then make sure to carry lots of patches or get a tyre liner. tyre liners are good things. we run them in cherie's bike. my tyres have them built in.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
