acera is generally 8 speed, deore is 9 speed. (pretty sure they are interchangable, but never tried. i know the 9 and 10 speed stuff isn't interchangable). there isn't much price difference between them these days. if the bike is 9 speed then shimano do a 9 speed alivio rear derailleur these days which is basically the deore mech from a few years back.

Sweet, cheers for the info Hugh.

Appreciate it! Time for some shopping.

_{Bought a Giant Roam, but had to get it in a 2XL frame. Not a bad bike, havnt really ridden a bike in about 8 years. Drivetrain seems to be ok too, got ACERA paddle gear in it. Now the question, anyone know of any good tyre and tube combo's for 700 series rims? Must be largish and pavement/road bias as its my new work veehickles}

[mad082]

If you're only going to be riding on the road, then get a slick. How skinny you want to go will depend a bit on the rim (how wide it is). The skinnier the faster you will go. As far as tyre choice, something like a maxxis refuse is a good everyday slick. They are pretty puncture proof without being super heavy. They go up to 700 x 28 (28 being the width). There are other tyres in the maxxis range that are a but wider while still being slick if need be. Something like the overdrive. They are both pretty cheap tyres while still being long lasting. There are cheaper tyres, but they may not last as long.

It would be worth taking a trip to your local bike shop and seeing what they have. And take your bike along so they can see how skinny you can go on your rims

Got it from my local bike shop, but they dont stock 700 series tyres usually lol. They are a good tyre(the ones on there now) but im just a little concerned with the wieght vs. contact area of the tyre at the moment. The shop owner(good friend of mine) should be back after this coming friday so ill go have a chat with him and not his workforce next time.

[mad082]

Ok if you are of the slightly larger build (which if you're riding a XXL frame I'm not surprised. You must be at around 6'5 - 6'6), then definitely go a 700 x 30 or 32 tyre then. Something like the overdrive or maybe something from the michelin range. Just make sure it is a tyre that will inflate to about 80psi or so (most will). And them just make sure you check the pressure every few days (or before every ride if you aren't riding that often). The tyres will lose pressure faster when inflated to higher pressures, and as the pressure drops you will be more prone to pinch flats

I go the ultra gatorskin tyres for my daily commute to work on road and foot paths.

They advertise it as really good for punctures. Unfortunately however with all tyres there always will be punctures. Have had about 4 in total on these tyres, i do think they work though, so no doubt if i had other tyres could be in excess of 8.

Lomg story short, I have continental tubes with the Ultra gatorskins 28. Ride normally once to twice a week 36km round trip.

[mad082]

gatorskins are a good tyre for preventing punctures. of course any tyre can get a puncture, but some are better than others at stopping them. at work we recommend the maxxis refuse tyres as a good everyday tyre because they are good for preventing flats, and cheaper than most of the conti tyres.

on my road bike i run either michelin pro race 3 or 4 tyres, or bontrager R3 or R4. all of them are a light weight race tyre, but they have a higher thread count in the canvas, which helps a little bit. but they are still more prone to punctures than heavier tyres. i check them every few rides for cuts. the biggest killer for my tyres is glass. if i find cuts that go through the canvas (but thankfully haven't popped the tube) i will put a small patch on the inside of the tyre. if it is just a small cut in the tyre then i just use a drop of superglue to fill the hole.

there are tubeless setups coming on the market for road bikes these days. i haven't had any experience with them yet (have plenty with mtb tubeless though). from what i have read though, they are pretty good, but i don't see them being the end of the tube.

[33GTRV]

yeah mad, im 6"3 but pretty heavily set, if you know what i mean. The 2xl frame was a perfect fit for me and it rode near perfect sight unseen and untested, so i trust maccas judgement (owner reccomended it for me, as he is nearly identical to me)

I think ive got 700 28's at the moment, but they are up around 70psi, so the rougher pavement can be a little uncomfortable.

[Nee-san]

3 punctures in 1 month on my conti's !

[mad082]

I've only had 2 or 3 punctures in the last 3000+kms on my light weight tyres. Always when going over that loose gravel you sometimes get at intersections.

[25GTT]

You can never pick it when your going to have a bad run of punctures, gives me the shits!

Hmmm might have to buy me some of those Maxxis refuse. Also what's a good tube to go with it

[xALmoN]

i'm looking for a rockshox reba from 05/06. marc, do you have any old stock lying around in the storeroom at your work?

[mad082]

Not that old. Really doubt you will find any shop with some in stock. Ebay would be your best bet.

[xALmoN]

lol yeah thought so. none of my mates have it anymore.

was my favourite fork of all time. them fox traitors.

[Down_Shift]

Bought my Scott Scale 80 2012 model for a pretty cheap price, picking it up on Friday.

hydro or cable discs?

[Down_Shift]

hydro.

Owner gave me a free water bottle and bracket, love it when they're friends with my mum.

[xALmoN]

i like hydro brakes too.

[Down_Shift]

Yeah, my old one was cable discs. Never liked it, hydro feels so much better imo.
