mid school profile cranks

[20to26]

I know that in 1992 Profile started stamping the arms of their cranks with the logo - has that stamp changed since then?

[thecaptain]

nope, pretty much stayed the same, sometimes you'l see a tiny 'TM' stamp somewhere around the 'profile racing' stamp, other than that they havnt changed a thing

Piccies of a GT stamped and of a 'TM' stamped crank arm that the captain refers to above - any ideas what year these are from btw?

I always thought that the newer cranks were stamped onto the rounded face of the arm as opposed to in a flattened off section of the rounded face as per the second photo.  I could have course be talking complete bollox mind

That GT made Profile crank is early 90's for sure. The bottom one is what I'm interested in - does that 'TM' addition to the logo relate to a certain date? ie are early 92 Profile cranks with or without the 'TM'

[thecaptain]

I've no idea about the TM stamping relating to a date, would be best emailing profile direct, all I know is that profile havnt changed the 'profile racing' stamp since the mid 90's ish

I had a set of profiles, I got around 94 and it had no stamp on at all - maybe they had been in the store a while.  Was well happy with them, up till then I'd always ran 1pc - they felt so solid in comparison.  Shame, profile as a company seem to be a set of shuffle munsterers - well the UK lot are anyways.

gt/profiles ran from 91-99
the non stamped profiles were somewhere in the early 90s,cant recall exactly when they started stamping them. 92,93,94 somewhere around there. ive always seen the tm logo on stamped cranks.
they also had the fusion cranks for haro with no stamp around 95,pretty much the same as the earlier unstamped ones.

Powerlite stamped Profiles are the same era as the GT stamped Profiles too. Apparently the Powerlite stamped Profiles are getting harder to find....I'm running a set of them on my 1992 Holmes.

Just had a look at mine after reading this, have 3 sets of profile cranks and one set is stamped MT instead of TM....

They might be quite valuable

LOL Betty - that's pretty weird -somebody must have put the stamp in the wrong way round or something...

So the bottom line is a new set of Profile cranks is going to be correct on a mid-school bike then as they haven't changed in 18 years

I've got some on my OS Haro racebike and I'm very happy with them.
