I'd just put it in the garage and say nothing. In a months time she'll say "I thought your bike was black" or whatever. Just say you've put stickers on it

mefo mx master is really good, but to be perfectly honest when it's so muddy on a heavy bike I suspect anything will be a struggle really..maybe try 20 psi first? you could do worse than have a chat to gwyn at treleborg tyres. he runs an HP2 and My 630 is shod with tyres from him (mitas ef07) and t...

Since this is my back garden I probably ought to join you but you always pick the dates of the rallies . So I can't. Could give you some routes though, haven't checked them all, but you can let me know what they're like.

All packed and on the way to the Pyrenees for the HUMM.

Welcome, I'm from just up the road at Great Ayton. So if you're up for some laning at some point, let me know.

Yep, I use them, beats carrying a compressor. Normally I carry a small bike pump just for finding holes in the tube to avoid wasting a cylinder.

Unless things have changed recently I believe you must have a guide, and I think you have to register the bike in china too. When I last looked at it, it looked like more trouble than it was worth.

Don't want to put you off trying though.

The 4.50 is the width in inches. I'm running 130 tyres on a 4.5" rim so would have thought 4.5" tube should be ok.

The lowest psi I'll dare run even with UHD tubes is about 20-21 in the front with 17-20 in the rear. The rear isn't so bad but I have no rim locks at present so don't want to risk ripping the valve out. If you're going be more brutal, then time for some mouses (spelling?)

The steel probably comes from china or Russia though
