    rear dropout width - 122mm on GT outpost

    You can cold-set the spacing yourself. That's a fancy term for "bending". I've done it before using a plank and it's not difficult. Here's some methods. Also, you will need to do this to make sure you get it centred. Bit of patience and it's all good. Grumps

    Would you be a MTBer now?

    I started MTBing when I was 20, after coming from a BMX and then road background. It was a combination of being a cyclist, and loving nature and bushwalking and wanting to be out there and explore and see more of the bush near where I live. I'm 53 now. Would I take up MTB now if I was 20...

    How much do you trust an old bike

    Steel and ti I have no problem taking out for a rip around the trails. Vintage carbon - not so, and aluminium - nup. I have a Mountain Cycle Moho which is wall art once it had become an exhibition of multiple hairline cracks in the CNCed chain stay yoke. I also have a Raleigh Technium and...

    Restoration advice on 1996 Kona Kilauea

    Re: Re: Yep. Rear derailleur and cranks are early to mid 2000s. Can't see the front derailleur or shifters to tell. V brakes not original so assume the brake levers are more recent as well. Not that any of that is a criticism - would rather see a vintage Kona being kitted with new bits to...

    Neighbours child has forks on backwards - do I say something

    Re: Re: Like how breakfast cereals have helplines you can call. I had the same situation once, up the park riding with my kids and a kid had his forks on backwards. I spoke to his Dad and said "Mate, I don't want to be "that guy" but your sons forks are on backwards which is actually...

    Protecting patinated parts with clear coat

    Not sure - most of my experience has been in restoring cars so I'm good with paint and steel and not so much on aluminium. There are some spray on clear coatings for intake manifolds (Eastwood, I think) though I've only used it on cast al and not high polished stuff. I think with al the better...

    Protecting patinated parts with clear coat

    Clear coat generally doesn't bond well to bare metal, it needs a base coat to stick to. There is a product available in Australia called Easy Phos which is a clear phosphate coating to protect bare metal. Car builders use it to protect bare metal while they get the panel gaps and other...

    Shimano XTR m900 paint code?

    In the absence of anyone giving an answer yet - have you tried an auto paint shop? They have spectra-something-or-other gadgets for analysing finish colours and identifying the code or matching with a custom brew. They can even mix it up and pump it into a rattle can. I doubt there is a paint...

    need an LTS / STS guru!

    A quick look at the 1998 catalog: http://www.retrobike.co.uk/gallery2/d/1 ... 1998-2.pdf Differences between the STS DS and DH appear to be: - the DH has a slacker seat post tube with a different lug at the top tube/seat tube junction - the DH came in S, M L sizing whereas the DS came in 4...

    The top 10 Retro Mtbs of all time ...according to GMBN

    I LOL'ed but then I went "yeah, that's about right". 1. GARY FISHER KLUNKER I'd replace that with one of the original Breezers. 2. JOHN TOMAC DROP BAR YETI It's a Yeti, with drop bars. Tomac made it what it is. I'd love the Yeti, but not the drop bars. I'm not Tomac. Tomac could outride me...

    Bearing free headset ??????????????????????

    You know how high end bikes come without pedals, because when you're buying a high end bike you're likely to have a preferred pedal system? Well... this is kind of like that. You know, ceramic bearings and stuff. Grumps

    Someone keeps letting my tyres down

    Re: Re: Ordinarily I'd say "yeah" but by the sounds of things, this peanut might not notice a bout of delirium or confusion. Sounds like he's suffering it already. Hang some advertising for a local kickboxing gym off the bike. If I was tampering with someone's bike and I found out they may...

    Lacing your own wheels ...

    Hell yeah, give it a go. I build my own wheels and I've had a set of (disc mtb) wheels last me for approx 50,000km of trail riding, endurance racing and general faffing about. It's a rewarding job. One piece of advice I would give is read up on the basic principles from the late Sheldon Brown...

    I disagree with most of the sentiments here. You've snapped a chain. That could have been fatal. This retro biking caper is not for you. Send me the RTS and never look back. :) Grumps

    Help identifying mystery GT bike

    And responses like that just add to the length, if not the boredom, but thanks, now we're up to 2 additional unhelpful posts. Apologies. I thought I was giving some assistance to the OP as a starting point. Next time, unless I'm 100% certain of a guaranteed accurate answer, I'll keep my...

    Help identifying mystery GT bike

    Nah, it's just a low end GT Arrowhead, truuust me. Send it to me and I'll dispose of it for you. ;) Seriously now, it looks like a 1991 Zaskar. Not sure about the markings though. 1991 Zaskar would be a good place to start researching. Grumps

    Cook Bros post V frame!

    It's okay to build a bike around a component. I had a set of Campy Delta road brakes. Built a De Rosa around them then found that the brakes were more show than go (or stop) so replaced them with Record brakes. Then I thought "it would be nice to build a bike around those Deltas, just...
