Anyone know of a similar cheapo minivelo that's steel? I want to make a seperable bike and have brazing gear but no Alu welding equipment/experience

Measure the outer diameter and inner diameter with vernier calipers. The outer diameter is the critical measurement, 51.8mm or 52.0mm would be my guess, 40mm inner diameter. Any good bike shop will have such a thing, take your old bearing shopping with you

If the difference between the parts is 0.1mm or more you'll never get them to fit with a rubber mallet unless the hammer is comically massive. Metal hammer, hit it like it owes you money Measure first though, if the difference between the parts is greater than 0.2mm something is wrong. Crown race se...

On the bike's drive side a 40 wide tyre is almost (but not quite, and I have no safety concerns) touching the chainstray, whereas on the other side it is quite some distance away. It's very easy to damage a frame from the tyre rubbing a chainstay. If a spoke snaps or your wheel is buckled while on ...

Previous generation Shimano 11 speed front derailleurs needed a daft amount of force to get them moving, especially if the cable routing is wrong (there are two clamp positions depending on cable entry angle). The newer ones need less force but are a bit of pain to setup, especially if you don't rea...

If you mean to cycle off road in Holyrood Park, then it is not allowed. The usual land access laws don't apply there as it belongs to the Queen. Information leaflet: https://pub-prod-sdk.azurewebsites.net/api/file/7a547642-2116-4305-9c22-aa6f010bbaa0 Historic Scotland confirmed in a tweet last mont...

I had a complete Shimano FF System but a colleague, perhaps correctly, thought it was junk and threw it out.
The description of your springs sound like Hope and Campagnolo freehub springs. Part numbers HUB504 and FH-RE014 respectively, worth a shot as readily and inexpensively available
Good luck!

There were definitely some people working at Dawes UK that only bothered to get braze around the joint, rather than all the way through! The later TIG welded Dawes bikes were quite different to the lugged and brazed bikes, miles tougher and stiffer because of the bigger tubes, especially the oval do...

Hi Thanks for the reply......was trying to use spare parts to build this which included a short cage R8000 rear mech and and matching 11-28 cassette. Don't think the mech can take larger than 30 teeth. Defo don't want to but a new RD and cassette. Was also thinking about removing one of the cogs (p...

Have you changed the BB or the crank? Maybe the outer ring is too far out for your derailleur to shift to.

Can't use P clips because it's carbon....
If it has a round seatpost you could use a seatpost mounted rack.
Probably not the best bike for cargo carrying!
If you started out with a solid alu through axle you could drill and tap either end and bolt your rack to that. Seems wrong...

I think these are the type fitted to Mirage, Xenon and Veloce. https://cdn.shopify.com/s/files/1/0858/4882/products/0000006273_203abd01-79e7-4d9e-90cc-fa4bac6f0587_grande.jpg?v=1595596249 https://www.condorcycles.com/products/campagnolo-veloce-vl600-pack-of-4-brake-blocks?variant=33378608522 I bet i...

I'd third band brake - terrible squealy hard to adjust things. Best avoided

Either way, fill that hole with a screw to prevent it filling up with water and corrosion

Fork rack mounts are either two water bottle bosses or one long boss that goes through a hole on either side. British frames are usually the former, Surlys and other Taiwanese frames the latter
