BMC AC01 off road
Postby pjtn » Mon Apr 24, 2017 1:59 am
Would it be ok to take this bike off of the sealed tracks? I'm not sure if it's very well suited to this kind of riding or if it could get wrecked. We would not be riding fast or attempting jumps.
I have seen some of the road bikes being marketed for off-road riding like the Focus Paralane and they have the same rims and tyre size.

I'm 70kg and currently run the tyres at 70psi.

I have had one flat, but that was after launching air off a washout and landing on a rock on a MTB track in the dandenongs lol.

I will have to check what the tracks are looking like, they can get quite rough. But everyone's advice has made me more keen to give it a go.

I've now changed to a rigid fork but offset that with tubeless Schwalbe G-One tires at ~45psi - heaven!

I have been thinking of changing to 32c tyres if we decide to ride off-road more often. The current tyres are quite new so it's probably best to try them out first.CycloTron wrote:My commute includes a fair bit of gravel/fire trails and my commuter is a flatbar with an Alfine hub and I used to have 28c Marathon Plus tires, which proved adequate but slightly dicey on looser sections of dirt/gravel, so you should be fine. Ride was harsh though, even with a front Headshok fork.

I don't want to lose performance when on the sealed tracks too much, though.

Indeed you'll find that your current setup will do just fine. If and when you do switch over to wider tyres, I would recommend seriously considering going tubeless. The G-Ones I now use are 35mm but handle road riding just fine, I can't say they're any slower or roll any worse.pjtn wrote:I have been thinking of changing to 32c tyres if we decide to ride off-road more often.

Tubeless is very appealing because you can repair punctures without taking it off. Which would make it much easier with the rear hub.
And 32c tyres should be less likely to get a puncture in the first place.

So, tubeless setups require sealant inside the tire which stops air from leaking and plugs small punctures on the go. The sealant eventually evaporates and will need to be replenished. You may need to do this around every 6-12 weeks or so, according to the manufacturers of the sealant.pjtn wrote:What is the maintenance like with the tubeless tyres?

Tubeless tires with sealant will seal off small (usually <5mm) punctures with sealant without you having to do anything. However, if there is a large enough hole that the sealant is defeated, you'll still have to remove the tire and install a tube to get you home, generally. I haven't had this happen to me, but then again, I don't ride through rock gardens etc. on my commute!

I rode my old steel roadie on fire road equivalent stuff plenty of times on 23mm tyres. Just had to be more careful than when riding something with fat tyres.

Tubeless tyres require a liquid latex sealant, which usually needs to be topped up once or twice a year. The required quantity of sealant varies depending on tyre size, but I generally put 30ml in roadie tyres, 60ml in 26x2.1" MTB tyres & up to about 90ml in 29" or fat MTB tyres.pjtn wrote:What is the maintenance like with the tubeless tyres?

Sorta, but not quite. If it's a small puncture the sealant will "self heal" the tyre before you even realise you've punctured. If it's a bigger slice that the sealant can't deal with it's just like a normal tyre; remove the tubeless valve & fit a tube. If it's a big enough hole, chuck a patch or tyre boot over it just as you would with a tubed tyre.

That's good to know. I've only been on the tubeless for about 4 months and you're right, every time I check, there's still sealant there, even though the manufacturer (Orange Seal) says the average life of the sealant is 30-45 days.
