- what tyres for….. fully rigid?
I have no problems running at 25 psi on my rigid bike but that’s probably down to me being 55kg. I use Mud X 2.0 because it’s generally my winter / bad weather bike. I’m running 2.2 Racing Ralph on my hardtail and wouldn’t mind trying the 2.4’s on the rigid bike in the summer. Personally especially on a rigid bike I’d go for a bigger volume tyre before upping the pressure on a narrower tyre.Posted 4 years ago
been out on my newly build rigid xc bike and i have to say i blody love it but the 2 times iv had it out iv ended up with a pinch first ride was just the rear but last night was a double bubble and left me with a 20 min walk
spec wise im running mavic crossrides with 26×2.0 sb8’s with kenda tubes running around 40psi
iv never had a problem with this setup on my full susser so is going hard on a rigid just to much for these tyres?
if so what lightweight tyres do u recomend that can take a beating?

I have a 2.5 nevegal singleply in the front of mine 🙂 Amazing how much difference a bigger tyre makes. And it’s not too heavy (650g or so, so barely heavier than the 2.25 etc I’d use), or very draggy. Bit pingy/reboundy though! Stick-e model would probably work better with the slow rebounding rubber.Posted 4 years ago
tbh i only weigh 11st myself and ride pretty smooth with unweighting the bike not being an issue,at the time i happend to be railing quite high on a berm on the man made leigh woods trails and just bottomed out amd both went instantly i do have some panaracer razor 2.3’s i could try and have 1.85 trailraikers for when it gets messy but they dont roll to well on the smooth newly made trails so need a fairly smooth tread patternPosted 4 years ago
anyone run crossmarks front and rear?takisawa2Subscriber
After overloading & breaking the weighbridge at the local Quarry, I havent the means to weigh myself but I’m up there are 95kg I reckon. 😳
Anyhow, 2.35 Racing Ralphs here running at about 25psi. Comfy & grip well, but I’m no rad-gnar merchant of skillz anymore so they dont exactly get a hard life. I sold the summer only Small Blocks because the Ralphs roll so well the SB8’s became my year round tyre.Posted 4 years agoshermer75Member
I also agree with above comments re changing riding style. I think about things like line choice a lot more than I used on a fs, which for me is part of the fun of a fully rigid. I had become bored of my local trails, and now they all have a new lease of life as they are a lot more challenging.Posted 4 years agotonydMember
Riding style no doubt contributes but this:
40 PSI is way too much on a MTB
would be my first port of call. I don’t think I’ve ever run a tubed tyre above 35psi and I’m heavier than you so I’d be playing with tyre pressures before fitting new ones.
Also, you mention they both blew at the same time? How did they fail exactly? Can’t be pinch flat at that pressure. Are they new wheels? Have they got rim tape?Posted 4 years agocurlie467Member
Anything and whatever pressure is in them really. Most of all, like others have said is to take line choice carefully and get weight off the bike, manuals etc
I actually tell people not to ride to close to me as i may suddenly shoot across the trail to avoid something.
Only ever had one puncture in the 18 months I have ridden with rigid forks and that was a thorn in the back.
Oh yeah, get the lightweight thing out of your head, it really doesn`t matter that much.Posted 4 years ago
Re pressures, I run bugger all in my 2.5. Basically the lowest amount my Joe Blow can register as being pressure, so I reckon in the 10psi ballpark. Did contribute to me knocking the tyre off the rim at the gt7 while doing something silly, mind, but it usually works fine.Posted 4 years agomaurizioMember
another plus one for the Conti Mountain Kings!
I run mine at 40 2.1 rear 2.2 front configuration and the only time i’ve pinched was in CyB and i’m hefty enough at 90ish! Low pressures are prone to problems if your doing jumps to rocks. Imho.
Also (no hijack intended) running rigid isnt about picking the biggest tyres at the lowest pressures for comfort – for that get suspension or a 29er 😆 . 2.2 will see you fine unless your doing dh courses fast and your amazing skills will see you fine elsewherePosted 4 years ago
ok new tubes in and the razor mx’s are on 26×2.3 comes up almost the same size as the sb8’s but with a thicker carcus and sidewall but more of a rounded profile will see how they feel on Fridays ride (was given them in a massive tyre mountain).
the whole reson for going back to rigid for me was after trying a lightweight cube xc bike a couple of years ago it was so easy to lug up hills in a race compaired to my f/s trance that is set quite slack altho if I can pick up a 100mm fork cheap then will prob opt for that to take of some of the hitsPosted 4 years ago
just come back from a superb ride on the razors griped like shit to a sheet on all surface even at mid- high presures also gave me allot more confidence to stay off the brakes and bank over on the sides more so currentley a happy bunny will be trying the m/kings on my next purchace tho, are they a good all year tyre or specific?Posted 4 years ago
