Re:
Resurrecting this thread as stumbled across it whilst doing a search for "Phil Sherwood".
Strange that no-one mentioned Venom/Sabre as the possible origin of the frame when there is a "Venom" sticker on the down tube.
Venom were a Midlands based company who operated in the 90's before disappearing, perhaps due to some management difficulties or maybe the booming popularity of aluminium and carbon as materials for race frames.
They built with both Reynolds and Columbus tubing and perhaps did "designer select" type builds appropriate to the rider/usage. As a result they may not have had a decal applied denoting the tubing.
Team Sabre were a racing team they supplied frame builds, so frames might show "Venom Racing Cycles" or "Sabre Racing Cycles" or even just Venom or Sabre.
I currently have three (alleged) Venom/Sabre frame builds. The first I bought is a Mick Kowal (heralded as perhaps building 7 frames per day when supplying Ribble Cycles), but in Venom livery and I haven't been able to establish if Kowal did frame builds for Venom or if this was a one off, merely painted at Venom cycles. The standard of build is very high, imho, and it features a Cinelli BB shell and race number hanger.
The second is a training frame with clearance for guards, has eyelets for same but rides very spritely and feels like 74 parallel. The seller said it had been built to order for winter training but in racing geometry. The fork crown appears the same as the one in the pics above, and there are some other similarities. Brazing is a little rough about the seat cluster but "It's held together, hasn't it?", as Bob Jackson's pointed out when I had it refinished there.
Lastly is the low profile TT frame which has shot-in rear seat stays like the frame above and is also finished in the Bianchi Celeste colour.
Unhelpfully, none of my frames are serial numbered.
They ride brilliantly apart from the lo pro, which is scary as hell, perhaps how it should ride...
If anyone has any information regarding Venom/Sabre, please feel free to add here or pm me with the info: I've not been able to get much online.
Many Thanks and sorry for boring you....
