Fatter tyres and modified seat
Permalink  
 

Regular forum readers will know of Robin Webb of Salt & Gold video fame.

Anyways up, Robin has recently had his wheels rebuilt to take wider tyres and also rebuilt the seat himself to better suit his needs ahead of shipping it out to the USA for his next desert/mountain adventure in a few weeks time.

The wheels were rebuilt with wider rims by Doug Richardson of Devon Wheel Building.  They have been converted to tubeless.

Robin wanted the fattest possible front tyre almost touching the gaiters.

After trying many tyres he has settled on the Mitas XT644 as best/favourite all rounders.

The new saddle is wider and fatter at the back for all-day touring comfort.

He has a big petrol tank fitted and has made new mounts for it so no petrol gets left in the corners biggrin

He has also  replaced the split pin on the rear axle nut with an R clip.

Good luck on the trip Robin!

Brian, Does Robin have a site/blog?

And do you know where in the US he's headed? Desert would be out west but I'd be interested just to know in general how he gets on.

How big are the tyres .

Why would you need such big tyres .

I always thought you could fit any width that will not rub without changing rims .

The one place i always foungd the ttr lacking in power is soft sand where it would only pull 2nd gear at high revs ,  very hard on the engine .

Soft sand is where u need big ccs .

Bike looks great very nice .

Very nice like that seat 

I've tryed the RClips but haven't had them stay in for a full ride . Vines here tend to pull them out .

Nice Tires nice looking bike well set up just put a new set of 644's on today after 5200 miles on the old set and I could have got a thousand more with just road work or dry lanes but it's getting muddy an sticky out there. will say this time round the front is more worn than the rear. on the BMW f650's you would go through 2 rears to one front in about 7 - 8 thousand miles

Fronts last quite a long time anyway so I will prob keep an enduro tyre on the front of mine. I would love a set of those tubeless rims!

 I have tubliss,s in mine...

can run them down to zero psi...

have removed the valves from mine

& gone for a ride on the seal.... handles

funny but would get yer home still ...sit on

100kmph...

but easy to fix on the trail with tubliss repair

tyre plugs ...

Even with tubeliss tyre yer still need air to keep tyre to

rim seal & stop the rim contacting the ground & getting dented...

but the 100psi tubliss bladder has 360* rim lock on

both sides even at zero psi in the tyre it is locked against the rim

the rim just can't contact the ground...

Great dam things.......

 ps..

on the dirt a half worn tyre with a tubliss gives

as much traction than a new tyre with a tube...

Yeah tubliss is pretty attractive idea. You could run about 12psi on a tubeless converted rim without too much tyre creep though I think. Tubliss isn't full proof though is it u can still puncture the bladder etc..

thinking pretty hard about getting some tubliss for my bike. AC10's are on my spares rims so don't spend a lot of time on the road with them anyway. I gather they are fine on the bitumen but just not DOT certified?

No they're not, and may not get your annual roadworthyness certificate if you have them, that's the risk you take.

Pretty cool to be able to ride with such low psi's though, mega grip.

I'm in Hobart so no annual roadworthy, which is handy. Plus I have spare rims for the road with D605's on. Yeah I like the idea, I think a lot of people overlook the traction that can be gained with low PSI's on a bike and these remove the risk of pinch flats. Which has happened to me when lowering pressures a bit too much.

Why are they not legal for the road? I guess the company just haven't had them ADR approved so to speak? Or other reasons

 tubliss themselfs say not for road use..

but they are made in the land of the law suit...

yer could just see some brain dead morron coming off

the dirt with 3 psi in the tyres & trying to get his leg down

on the first corner.... then blaming everyone ealse because

he came off... 

can't blame tubliss for playing it safe...

we use them here on the road with normal road pressures

with no issue at all....
