On-One Il Pompino frameset

I'd wanted one of these for a while, and when I saw they were going to do a limited run with a TAF neon green glow in the dark finish I had to have one. Since I come from a more road-ish background I wanted a more roadie-type frame for cross that was fairly cheap and could take some abuse and this seemed perfect.

It took a long-ass time to get here from the UK, but shipping costs were not outrageous. It arrived in a minimalist box, but was well packed. No issues there.

It took me a while to build it up, but in my usual style it's a mix of leftover, scrounged, and bargain bin parts. Everything went on pretty easily. The head tube was nicely milled and the BB threads were in pretty good shape. There are thoughtful touches like a pump peg, chain hanger, and stop for an internal gear hub. One minor complaint is the cable stop on the monostay is not perfectly aligned, but in practice it's not an issue. I do wish the frame shipped with bolts or something to plug the rack and fender mounts, but electrical tape works. After purchasing a fork mounted cable hanger I realized the fork was only drilled and tapped at the back. Doh! Since I wanted to run the fork mounted hanger I took the fork into a local frame shop and had them drill it out.

I've always run 32-ish cross tires on this frame, so I can't comment on the handling with skinnies. At low speed on pavement the steering is a tiny bit squirrely, but riding dirt/grass/mud it feels great. On loose terrain like fine gravel the squirreliness shows itself at times, but overall the handling is predictable and solid. I recently switched from a 120mm to a 130mm stem on my XL frame and I feel like that's helped balance out the bike and given me more confidence cornering.

Ride quality is where this frame really shines in my opinion. It's nice and stout without being harsh. I've raced it 5 times so far and have ridden it on some pretty bumpy courses. I'm still learning how to stay loose on the bike, but I've never come away feeling beaten up by this frame. It's a very confidence inspiring ride, and the stoutness means you get good feedback from your tires. On the street the stoutness translates well to climbing.

There are a few things I'm not a fan of. My biggest peeve is tire clearance. From what I understand On-One's intent for this frame was more burly urban commuter/sw8 fixie than cross bike. The assumption being that the user may want to run a bigger chainring. Unfortunately they accomplish this by bringing in the chainstays so they meet the bb at a fairly narrow point and the outside of the drive side chainstay is not crimped or manipulated in any way. The chainstays are crimped on the inside which affords some room, but not much as they narrow quickly. In theory the long track ends should be a good thing for frequent gear changers, and that's probably true for use with more road-ish tires, but cyclocrossers who are hoping to run a 17 freewheel one day and a 20 the next will probably want to look for other options. The crimps are short and there's only so much room to slide the axle around in the track ends before the tire rubs.

So how big a tire can you fit? I've run Continental Twisters ("32") and Michelin Mud 2 ("30") so far on TB14s and both *barely* fit with enough clearance that I don't feel like I'm going to eat shit if my rim gets bonked a little out of true. I feel like the clearance could be improved without altering the geometry or basic character of the bike, but it would probably increase the cost.

My other minor complaint is the fork. It would be nice if it came drilled on both sides. Most fenders (Honjo, etc... excepted) come with hardware for this. The hole on the back is tapped, so I guess it would look cleaner, but in the interest of sturdiness and mounting lights and other accessories it would be nice for it to be drilled all the way through. Finally, the fork is a bit of a pig. The unicrown doesn't bother me, but I think it could have been done a little more attractively and with less material.The upside of that is it's burly and inexpensive.
On-One deserves credit for making the fork optional, but it would be nice if they posted all the specs so the customer could make an informed decision.

I have had some issues with throwing my chain on bumpy terrain (chainline is good), but some $8 Origin 8 chain tugs and a new chain seem to have taken care of that.

120mm spacing in the rear is kind of a mixed blessing. The upside is with the sw8 fixie boom (and its tapering off) there are lots of cheap and decent wheels and hubs to be had (my rear hub is a $20 IRO). The downside is you are not going to find a neutral rear wheel at a race, prebuilt tubulars are a bit harder to come by, and you have to swap freewheels instead of cogs on a freehub body.

Finally, the name is stupid. Naming a bike the Italian word for blowjob is some 5th grade shit.

Overall I am quite happy with this frame. I'd give it a B+. With better tire clearance it would be an A no question. As long as you understand its limitations I think it's a fantastic deal. IMHO the ideal user is someone who wants to pick their parts or has a bin of stuff already and wants a bike that can take some abuse. It would be great for a mix of cross/commute/sweet fixie duty. It's not 100% ideal for a cross-specific bike, but for the price it's pretty solid.

On-One has recently started selling in the U.S. through Titus, but they routinely have good deals on parts, clothing, and other stuff on their UK site so if you're considering a purchase and are in the market for some other items I'd check both options and see which is the better deal.

What he said.

I love mine, I find it very predictable and it goes where I want it when i want it. Feels lighter than it is too. Plus it is really comfy, I feel like it absorbs bumps better than my steel Jamis.

that's for the notice, going to pick some up

Also as far as the prices, it looks like everything is around 50% off right now, is this the kind of deals you're talking about or does it get much cheaper?

Update: Apparently On-One has lengthened the chainstays on the current version. Claimed tire clearance is now 35mm.

Euan, thanks for the offer! I've actually ridden a Pompetamine briefly before, which I assume is pretty much the same thing as a Pompino. It was enough to get me really interested in building one.

Def need a large. A current fit told me my road bike with a 58tt only really fits me with an <90mm stem. I'm all legs with no torso and no flexibility. The Fit Kit told me 7 years ago that I needed a 55tt, but I never really believed it until now.

You can still get the kaffenback, but it's been derped up with SS/geared and disc/canti swapouts. Nearly bought an original one (with dragons painted on it!) a little while back.

I have been let down by the swap out design, let alone the color choices.

I built this up for my Aunt last year.

My ex a while back had one colored to match the namesake better.

My white one should be here in a week and a half. Didn't know there was a sparkle. Bonus! Now all my road bikes will be blue and my cross bikes will be white. All I need are some red mtb's and I'll have the colors of the czech flag.

I have a compact crank, bars, post, levers and I'm gonna use my sweet fixie wheels (formula to cxp22, 32 hole) for now. I need a saddle, brakes and a fork. And probably another set of pedals so I don't have to swap them between races again this year.

Finally built mine. It went together very smoothly. I've only ridden on the road and I'm just getting the fit dialed in, so no real impressions yet. Gonna race it tomorrow and will have a better idea of how it feels after that.

built up the pompetamine (disc version) to mess around with and use as a vehicle to take up a bunch of parts cluttering my garage.

there isn't much clearance for the disc brake with a 160 rear. don't know if the bb7 mountains i'm using are bigger than most other mechanical disc brakes, but it did take some creativity to get working.

really like how the bike handles. has a bit of that sweet fixie responsiveness, but fat tires and disc brakes. took it on some mellow singletrack and had an absolute blast.

i'd really consider keeping it, but i built it up for the express purpose of selling it and have to move it on.

Does it have the rear disc tabs within the frame? If so this and BB7s are a known issue with some On Ones (like my inbred).

I'm about to pull the trigger on the current version. My Cilo is a 55tt and fits pretty well, am I looking for the M with this?

Also, it says it clears 32's or 35 slicks. Any chance it'll fit 32's studded and fenders? Coz otherwise, I'm out.

Not sure about studded tires, but mine fits 35s (compass bon jon jovi pass on TB14s) under fenders (SKS P45 longboards)

FYI you'll have to drill the front of the fork crown yourself if you want to mount anything there -- already drilled and tapped on the back of the crown though.

Have no personal experience with the current version, but the geo is slightly different.

I had my framebuilder drill the fork on my neon green one so I could run a fork crown cable hanger. Works great.

Man, I really want to get some fancy tires for that bike for spring and summer.
