I have been scouring the forum for posts regarding front end geometry and shock length specifically for the TT1. I hope to replicate (in time) the Jimmy Adamo TT1 so I guess the best person to ask is Lou or anyone who helped with the restoration, I would like to know the shock length and triple clamp dimensions used on the Adamo bike.

Hi Ducfan, that frontend was a rare 38mm Marzo mag fork set. 195mm center to center on the triple clamps. 320mm shock length center of the shock eye to center of eye. What forks and wheel combo are you going to use? Nothing ever really fits first try! Lou

Hi Ducfan, nice combo. Just got off the phone with Steve Munro and he is fitting M1R's as well. If you are using the 195mm clamps (which look good and seem to make fitting the fairing a little easier) you will probably have to mill about 2mm off the inside of the fork legs to clear the floating rotor buttons if in fact you are using floaters. This is also dependent on the width of the campy hub you are using. This width dimension is from the face to the face of the hub where the rotors mount. I have seen these vary a lot from campys I've used. Do you have the size for these 18 inch campys? With the last wheel I fitted I had to remove .250 inches from either side of the actual wheel hub material which was quite 'meaty'! That being said the wheel I am fitting today needed no changes to the wheel or forks but I had to mill down the brake hangers to bring the calipers further in towards the hub. This is always a challenge when building these little machines as these were never a 'production' bike and we are using spares that we can 'find' from different sources. This is all assuming you are using 41.7 mm M1R's, they did make 38mm versions as well. Good luck. Lou

Thanks Lou I have the 195mm clamps some of the parts I got from Steve a while ago he did warn me of the disk clearance problem I was looking at the Adamo pic in your reply. The top clamp looks very much like my bevel 750 sport top clamp for the 38mm Marzocchi's. Do you know what offset the Adamo bike clamps have?

Hi Ducfan, I am pretty sure they have a 25mm offset like the early F1A. Lou
