On One Pompino owners...

Haha, it's a Cannondale one that didn't match the bike. I enquired in to hydro-dipping it, or I thought I might spray it but in the end I opted to Sticker-bomb it! There's something quite therapeutic about doing it, I kind of want to do it to my whole garage wall now!

Looks great. I always find it interesting to see bikes with a combo of rim and disc brakes :)

Love it!

Thanks :-) I'll finish it off at some point and get some finished photos up.

I'm selling my green Pompino frame (check back a few pages for photo), size L, if anyone is interested. Stronglight chainset and corresponding bottom included also. LMK if interested. Not sure what it is worth. Located Bristol.

dayum why no medium v4?!

I have DM u :)

Dusted off the pomp after a few months of riding other bikes, and finally got around to putting on a in-line post.

Hi everybody. I bought a new pompino raw frame a week ago. I have a miche primato crankset. Does anybody have this combo? What size 68mm bb compatible this? I have a 107 mm but the crank almost enter the frame both size.

I had that combo on a V2 (or V3?) and it was fine...

Do you have a picture please?

I had the same problem with a V4 and a Omnium. For me a S300 solved it.

I don't sorry. You mean of the crank arm/chainstay gap?

With Primato's you need a Shimano UN55 113 mm bottom bracket

yes

or campa 111 maybe?

Would be even worse/require an even longer BB spindle; Campag/ISO taper is (same angle but) smaller at the end than JIS. Would position crank similar to a 103 or 105mm JIS BB.

111mm Campag ISO.

Token make one I think.

Oh shit yeah. Miche switched to jis didn’t they?

Which type are these cranks?

Cranks are the same, the bb was the only change.

Ok. What a kludge.

Pomps don’t seem to have the claimed 42mm chain line.

I’ve used Campag taper 111 and 109mm on other frames.

I think the cranks stay the same anyway.

I guess maybe where the chainring sits in relation to the taper might have changed?

Does anyone know if the stock bb length changed when they changed taper spec?

When you say “Pomps don’t seem to have the claimed 42mm chainline”... it’s be teaching you suck eggs to tell you that a frame doesn’t determine the chainline right?

I mean if you use a normal, regular length crank you can get problems with 42mm chain line. Therefore the frame isn’t suitable for a 42mm chain line.

A 109mm Campag taper gives a 42mm chainline on my (10 year old) primato cranks.

Otp bikes using Miche used to use the Campag 111mm. Not sure if that’s still the case.

I know we have used 107mm Shimano (and other jis) bbs with them at work and we have done so with cranks that’d have been made when the stock bb was the unflanged one that was (I think) iso taper and with newer crank sets for which the stock bb would be the far better, flanged jis one.

I have no idea what length those unflanged iso bbs were but we have still got them in the smallest bikes so could measure one.

I can’t be sure but I think the new flanged Miche B.B. is 107mm so all points to there having been no change in the crank when they changed B.B. taper.

Re chainline: I’d say it sounds like 42mm chainline is possible but only with selected cranksets, guess that’s the price you pay for large tyre clearance plus 120mm rear end (and the q factor etc that comes with that) minus lots of money being spent on things like design and manufacturing tolerances.
