Off-road / gravel / mud fixed-gear bikes (whisper: tracklocross)

I guess not! :-)

shame as it does indeed look like a 52ish and is nicely ratty!

Yeah I was wondering about that. I was planning to go square-taper, for the axle-length flexibility, and hope I can get some cranks in close enough before hitting the chain stay.

I'd be keen. What size is it? Also, what was the clearance like with the mudguards?

It's a large.
Those are 33.3 Jack Browns, I dare say 35mm slick at most (can't say better than that at the moment as the back is rubbing horribly because I lost the brake bridge).

Nice! Midnight Special fork?
What's the front brake? Magura Marta?

Yeah midnight Special fork and I’m not sure what brake is in that photos, but he’s got a klamper on it now I think.

Legit! Brklss dynamo, not sure I've ever seen that. Sense and Insensibility

I spotted this which might be similar to what you're after looks like a prototype mulo with disc mount and 135 spacing and tapered ht, on the planet x ebay. https://www.ebay.co.uk/itm/404260355124

Oh cool - thats interesting. I wonder if they'll end up selling a disc tab Mulo?

Cheers for thinking of me! I've actually picked up a Day One one, which im currently waiting on a wheel set for.

I did try to UTFS on this thread but weirdly couldn’t find anything:

What kind of gear inches do I want to be pushing on a rad fixed pengycross rig?

My track bike is 70something when I’m riding it on the road, but I’m assuming a fair bit lower off-road? I’ve currently got a 44t chainring and sprockets 14 thru 18. Hoping I can assemble something useful out of that…

Its a little dated now, but 63xc.com/ was named after the supposed ideal ratio for off-road fixed. Perhaps start around 66 as you'll be used to higher from road?

Ah ok, cheers. yes that sounds about right. I was just playing around with bikecalc, and it looks like need to get myself a 19 or 20 cog, or get a smaller chainring.

63 is a decent all around gear. If you have the ability on your rear hub spin a cog on the other side for off road. My best fixed off-roaders use ~63 for a primary get around gear and in the mid 50s for trail gear. It’s steep and twisty in the single track here.

I run 42-19 with 700x34c (60 1/4”) on the pest, spiny as all fuck on the road, but perfect for SFAB and playing in the woods.
