Converting an old mountain bike for touring - Tubus front ra
Converting an old mountain bike for touring - Tubus front ra
I've adapted my old steel mountain bike for touring. Front rack mounts provided by Tubus external rack mounts. Not tested these as yet. Does anyone have experience of using them?
The bike has two bottle cage mounts, but I could do with a third under the downtube for my fuel bottle/Bike Buddy.
I've looked at a couple of options and the Monkii one looks interesting. Has anybody used one of these? Any thoughts on how sturdy they are? I can't afford to have any movement because of the close proximity of the fuel bottle to the chainset.
I want to mount the fuel bottle below the downtube in case of spillage. I use unleaded petrol for cooking.
The other option is to have bottle cage mounts rivetted into the downtube itself. The frame is double butted Tange. Again, has anyone done this?
Cheers in advance

If you mean these sort of things for clamping to the fork when you don't have a braze-on halfway up the leg, then yes. I've been using them for about 25 years on a couple of different bikes without any problems.

My front rack is a copy of the Blackburn one in the picture and is currently on a converted mountain bike.

The clamps look fine to me, I can't see the rack twisting around as it's held in place by the eyelets at the fork ends.
With reference to the bottle cage my old winter bike used to have only one set of mountings for a bottle and I used something like thing below for a second bottle. You could use the same for an under down-tube bottle. Not the prettiest thing but cheap and simple.

Nice idea but it wouldn't work well with the Bike Buddy. I'd have to undo the retaining springs each time I needed to access the fuel bottle.

I fitted front rack mounts like yours on our old tourers to be able to fit Tubus racks. They are still working fine nine years later.
As regards a third bottle cage mount I have used these on the same bikes. http://www.rosebikes.co.uk/article/klickfix-bottle-klick-bottle-cage-adapter/aid:254953
The fixing comes with two straps a short one and a long one - the long one easily went round the large downtubes on those bikes. The only thing to be aware of is that the bidon holder is a couple of centimetres from the frame so you might can run into clearance problems with a long/large bottle hitting the front wheel. There is a bit of movement between the two parts of the mount but not much. I always mount my fuel bottle within the frame/above the downtube as under the downtube is rather too exposed for my liking. Only things I can do without go there.
So long and thanks for all the fish...

These sort of clips to hold an extra cage are neat, unobtrusive, inexpensive and were used for many years when braze ons weren't usually fitted. http://www.ebay.co.uk/itm/Velo-Orange-B ... 2ca0f27df8

Reassuring. Cheers

This is the same one that another poster suggested. Unfortunately they won't work too well with the Bike Buddy.

I followed the advice of someone on here and did something similar - good old fashioned jubilee clips gripping onto the wilkinsons cheap but perfectly decent bottle holder - you need a bottle holder with metal in the right places for the jubilee clips to clamp around.
Worked fine for me for the price of the bottle cage - i already had the jubilee clips.
Oh, have also used those tubus mounts on the front forks - they are fine.

I fitted a bottle cage under my downtube using rivnuts: they cost pence (ebay), easy DIY job to fit into a 7mm (IIRC) hole.

Think I'd leave drilling holes in my frame to the experts... and minimum.
I had mounts brazed onto my forks and drop-outs (by an expert ), but my positioning of the mounts on the forks wasn't so great and resulted in a sloping Tara. Couldn't blame the frame-builder as I only gave him the removed forks and not the rack either. Silly me. Anyway, the forks were a spare pair and can still have more mounts added another time... There'd still be far less than the clutter on Thorn forks!
As for bottle cage mounts, I got a super cheapo rubber thing from Decathlon the other day for the Brompton, which could be used temporarily, but would be no good for your purposes over time. Monkii could be good, dunno.
Nice bike, btw. Is it a Marin? Actually looks a bit like the Park Pre Mme used to have. I like the tyres too- Big Apples? I want to get some of those.

That was my view too, until I noticed that the rack mountings on my seat stays look remarkably like rivnuts. 7mm hole in an 18mm diameter tube? I'd have called that reckless, but Mr Dawes has made a lot of bike frames, and I assume he knows more about it than I do. So I consulted - informally - a friend who's a chartered structural engineer, knows nowt about bikes but a lot about structural beams and tubes. He said he thought the effect on the strength would be negligible, so I've now got bottle cages on my downtube, and also on both sides of my front fork (44mm x 24mm cross section, roughly). Granted I'm not overweight, rarely ride offroad, and generally treat the bike fairly gently, but it's done a good few thousand miles since with no hint of a problem, so I feel it was an OK call.

Not sure what the brand is. I bought it second hand minus decals (other than the Tange sticker). I suspected Marin, but it's got quite distinctive grooves in the top tube. Not something I've ever seen on a Marin - or any other bike frame for that matter.
Yes, Big Apple tyres. They're great for suspension and they roll really well. I've picked up some folding Mondials for my next trip, but the Big Apples are pretty good on both towpaths and tarmac.

Re: Converting an old mountain bike for touring - Tubus fron
Some old GT frames have a groove on the underside of the TT, but that is clearly no GT.
Colnago do tubes with kinda fluting, and IIRC a friend has an older Merlin (UK) with shaped tubing, maybe grooves, not sure.
Seems a few bikes had ribbed downtubes and some had spirally tubes;

Seems from reading that thread, Tange made some of the spiralled tubing, so perhaps they made grooved tubes too.
