of course. here come two pictures. hope they're clear enough. The brand is "simplex"

Hi,

my rear tourney broke a few days ago on my 80ies roadbike. Does anyone know if just buying a new 6-7 speed shimano one would fit, or if I need something more 'special'.

Many thanks!

hi, having to juggle work and family I'm very slow at fixing this bike. Thank you all for the help this far! I'm currently wondering if it is possible the exchange the the entire "cone" stem, with a "quill" stem such as: https://www.ebay.co.uk/itm/333148173457?ul_noapp=true.

I'm having a hard time measuring if my current stem has a diameter of 22.2 or 22 mm as the two are so close together. My current stem's circumference seems to be very close to 7 cm, which should hopefully make it a 22.2 mm.

Also, should there be any reason why my fork should not "take" a quill stem?

Many thanks!

oh, now I see. that makes perfect sense.I misread part of your previous post. Thanks again for being so helpful

thanks! not sure if the photo shows it Ok - the dark spots are mainly dirt, which i didnt manage to clean - but the crucial bit of course is that the 'pip' is missing.

Are those things coming in universal sizes? Would something like this work: https://www.ebay.co.uk/itm/Quill-stem-b ... 100623.m-1

Dear all,

thank you for the informative replies and apologies for my so incredibly slow answer! I unscrewed the the expander bolt and noticed the following (photo attached):

1. the bolt's top is slightly damaged - I barely managed to unscrew it with a 6mm allen key, but it seems like it needs to be a 6.5 or 7mm key to loosen and tighten it properly - is it possible I'd need an unusual key like that?

2. I couldn't find any 'pip' on the sides of the wedge, neither any trace that there was one. Only on top of it there is a tiny "something" (barely visible on the photo), but I am unsure if that's what we need.

3. Apart from the above, the bolt and wedge seem in OK condition. there's no major rust or anything similar.

Do you reckon things could work out with this bolt and quill stem or should I rather try and get a new one?

Again many thanks!

thanks for all the replies. I assume it was in this condition since I bought the bike second hand. I didnt notice it at the beginning because it is only apparent when more pressure is put on. I'll remove it completely and have a look in the next days and will let you know. Again, many thanks!

Hi, my Peugeot Clubman's handlebar is slightly lose - meaning if I hold the front-wheel still and invest pressure to the handlebar it turns left and right. I tried tightening the hexagonal bolt at its top - and managed to tighten it a bit further - yet still the problem persists.
Any idea where the problem might be?
Many thanks for any advice!
