[Closed] SPD-SL's on an MTB ?

As long as you never have to get off the bike at any point, it should be fine,

This

shouldn't be a factor really, it's only going to be a local XC ride, I may have to stop and fall off in the woods on my own... but apart from that, shouldn't need to stop at all. No roads, junctions etc.

Good luck with that then... 😕

SL's are crap when introduced to mud.

elaborate on 'crap' please. fall to bits ? don't work from a clip-in perspective ? don't go round well ?

Slightest bit of grit/shit in your sl cleats and you ain't clipping in. I have to tread carefully in the winter when venturing into the hedge for a piddle.

More likely to not be able to unclip when they get dirty.

There's a reason why you don't see people with them on Mtb's they don't work.

Have you actually tried?

If you stay clipped in you'll be fine, I'd suggest it'll be a pain if you put your foot down in some mud, but they're not gonna explode when you go through a puddle!

A friend used them for some XC races with no ill effects.

You can get entry level shimano for £16, pedals and cleats, if you look online. Do it properly otherwise you'll not know whether they really work, and if you don't like them you'll get £12 back for them ho issue - I'll buy them off you for one!

May need shoes too, and frankly if road shoes are the only option I'd rather use SPD-SLs than SPDs.

Don't see why it would be an issue for occasional use. They will obviously wear faster with the grit and mud but it I cant see you not being able to unclip after just 1 ride.

As above, they MIGHT be sticky if they get mud in the mechanism or between cleat and pedal but they'll more likely be fine for the riding you've described. I don't think that the cleats will last long though if you do it regularly.

Between mud and pedal is where it'll cause issues, as the tolerances are quite tight, moreso than SPDs, however they're a very open design, so they won't clog per se. The issues will be grip if you put a foot down and having to kick the pedal over to clip in. I've used Keos on the MTB a few times and not died.

Can you make it up all the hills?

If you have to get off and push any bits, the cleats can die very quickly on rough ground.

Don't ask how I know that.

I've recently adopted SPD SLs on my Road bike, there's no way they would be a good idea on my MTB, there is a reason Shimano, Time and co have two different systems for on and off-road use...

Go shopping for some m520 or M424's I'd even say you could probably get a decent pair used as they're nigh on indestructible IME...

Then for cheaper MTB SPD shoes I've found Decathlon's basic trainer style ones aren't actually too bad at all for the money.

Shop around, it doesn't have to cost you a fortune...

I don't care if it costs me £10 LOL... thats' £10 more than I'm prepared to throw at it today. I've not got on with SPds in the past, so it was a fleeting idea rather than a lifestyle change.

If it's not a great idea, i'll stick with flats and 5 10s

I'd say fine for the odd ride when you're confident you won't be walking, but not a long term solution. Ignore the doom mongers who've never tried it telling you they'll explode.

Also be aware that road shoes generally don't have reinforced toe boxes like MTB shoes, so any rock strikes or anything could hurt more.

njee20 is correct. It's not an ideal solution by any means but if it is a ride with no walking and minimal chance of needing to put a foot down you'll be fine. Try it, got to be worth a go before you thrown any money at it.

I tried it once, clipping in is almost impossible with even the slightest bit of mud.

They don't float as easily as SPD's (more allowing the foot to find it;s natural posiiton and stay there, whereas SPD's allow constant movement) which feels wierd in corners/jumps.

They don't unclip very easily in a crash evenont he lowest setting the release tension+friction is much higher than SPD's tension.

The cleats wore out to the point of not staying in the pedals before the ride was over (and cleats cost more than entry level SPD's).

You'll just bollox your Road shoes, so stick with the 5-10's...
