Which ever size the mousse I just bought fits correctly, seriously I have a selection of sizes of tyres stored away and find a tyre the mousse fits because mousse sizes are all over the place, its like pick and mix, I have put pictures up before of mousses that are supposed to be the same but a blind man on a galloping horse in a thick fog could see they are massively different in size.

I am well aware I could make a bike set up better for one small section of a track but anyone who had ridden proper enduro and especially rally will know you can be blatting down a fireroad (all lee ever does:rolleyes:) one minute then in a section of track that looks like it should in be an extreme enduro through bogs over trees, big hills you name it the next. You usually do not know what is around the next corner, it rearlly could be anything believe me I have done a few. Much easier for the rider to shift his lardy arse around the bike to make it work on what ever appears in front of him and with what ever he has under him.
Getting back on topic the same applies to tyres, no matter what you have got fitted there will be sections of the course that are not best suited to what you have fitted, what is very important is the mousse is a good tight fit in the tyre hence me saying I pick the tyre size based on the mousse, the last thing you want is a loose mousse breaking up and allowing the tyre come off the rim, you could be stranded for hours or overnight.

I totally agree. But having a bike that is well set up for the majority of what you're riding (it's always a compromise) is a good starting point - hence the choice of front tyre - I stick with a 90/100 because 90% of my riding is rooty/rocky/snotty technical riding - and in that, it makes a difference. Same with mousses/tubliss. I run tubliss because having 4-6psi in the rear makes a much bigger difference than removing the tiny risk/impact of having a puncture. Should I ride a rally, then mousses are the ticket.

Point being, these things DO make a difference. Never going to make someone go from 10th to 1st but might make a big difference in enjoyment and confidence.

And like you said, there is a hierarchy of effect - correct mousse is probably more important than tyre profile. Correct springs and sag are far more important that a full revalve. New tyres are far more important that whether it's a maxxis or a michelin. etc.

For tyre size and moose fitting? [emoji85]

I’m with Lee on his point above... that’s how you need to set your suspension and pick your tyres for the desert terrain... XC type setup is probably the sweet spot.

You can set your bike up for all sand but first high speed detour through some rocky sections, you’ll be leaving the desert in a chopper... same for tyres, scooped knobbly sand tyres are great but usually toast after a couple of trips to the petrol station. Just need to pick somewhere in the middle that works and go for it.

I am utterly shit off road (having taken it up in late 40's) and kind of a competent above average road rider, but I still know when I like the feel of a bike and will play with suspension until I like it.

Off road is harder for me to judge as its not as simple as riding the same section of road as you never hit exactly the same bumps / tufts / ruts from one pass to the next (well I don't!)

Having spent a chuck of change having FE suspension professionaly serviced / reworked for me what I have noticed is it "feels nicer", I am more comfortable, my dodgy arthritic thumb joing hurts less and I no longer feel like I have been whacked on it when hitting bumps...

.. Very much doubt I am much faster, but the extra comfort and confidence means I ride better, plus spend more time looking where I am going rather than scanning the ground for bumps to avoid.

I also think it is harder to setup an Enduro bike as most of us will ride a lot of very varied terrain, regardless of if trail riding or doing an Enduro.

Am wondering if the taller tyre might help with comfort for us old folks with buggered joints?

I went from 90/100 to 90/90 for first time last tyre change and for shits n giggles I ditched Tubliss and went mousse same time.
Not quite as comfy at Cowm on the marbles but was fine. Didn’t notice much at Tong. I’d say I felt like was easier to catch the front before it washed out but could be bollox.

I used 90/100 Michelin Enduro tyres for years,but my 500 came with a Metzeler 90/90 front.
It didn't give as much comfort as the 90/100's but was more accurate,could change lines faster and best of all I hardly ever lost the front end.
I guess it's all about confidence in not losing the front end and the 90/90 always feels planted to me.
Cheers

I’m same as you Smiler. Been on mousses for two years so no idea what Lee is actually on about other than being wrong again. I to fancied a change. There isn’t as much traction now but I also can’t have the race ending puncture I never had with Tubliss. Mousses are simple though. Buy. Fit. Ride. They are expensive though.

I simply can not understand why people can’t feel differences whether it be tyres, mousses, gearing, brake pads or something like bars. They definitely do improve your comfort or confidence even if you are at the back. I’d wager that it’s even more important for a slower rider to find improvements. It’ll make them safer and more confident and let the explore better technique etc. Fast guys seem to be able to use anything.

I’d certainly not take any advice of someone who is happy to use a well fucked fork tube.

A few simple measurments (more accurate than the water bottle ;)) tell me using the damaged fork tube will be ok until the new one arrives, need to get some riding in before the many covidiots get us back in to lockdown again.

Pindie you have clearly been selling your soul again, get some discount in exchange for promoting products/services, getting people to spend when all they need to do is look in the mirror to see the problem.
I have nothing to sell prefer to pay my way and be stright with people:)
