I've come through to my parents home and in the garage is my trusty old Raleigh M-30 mountain bike in all it's (former glory) BACKGROUND I got in when I was around 11/12 (so around 1997) and it provided me with hours and hours and hours of good times. I raced people with it, tried going off road, fell MANY times, and even went airborne more than I should have. Let's not forget the skids I did that weirdly did not destroy the tyres. It's HARDY! Steel frame Shimano 15 speed (3x5) Shimano calipers 26" wheels When I realised it was a 26" my eyes lit up as I realised I can actually do something with this bike!! The bike will be used for some gravel riding, road riding, and some riding down the promenade. Gravel tyres seem to give the best of both worlds and I'm keen to try this as a build. MY IDEA The plan is to obviously turn this into a GRAVEL bike or something like that. Wheels These obviously need to be changed as the wheels are warped and the rims are rusted. This is also the major elemt that I will change. As this will be used as a gravel bike, I wanted something thinner, sleeker, and not as MTB like. There are a few options: Do a straight swap with another 26" tyreTry to fit in a gravel 700c type tyreBe smarter and use a 650b or similarThe clearance looks like I could squeeze in the 700. The 650 may be a smarter idea. Tyres I want to put in something that's not very MTB like. Haven't made up my mind yet. Brakes, Gears, Drivetrain When I said that this is hardy, I meant it. These honestly do not need to be changed! They work extremely well, Even the brakes stop things DEAD. All I want to do is: Wash and LubeTest out the cables to see if these need to be changedChange the brake pads as the rust would have eaten into themGet a gold chain (not really)The 3x5 is ancient and is a relic of a kids bike but it really works and since it still functions really well, I want to keep it. Handlebars Keep these for now but consider upgrading to drops. Seat This looks old so will change this but this is not a priority. QUESTIONS TO YOU... What do you think? Am I insane? Is this a great little project to go ahead with? I would also like some advice on: What are the best wheels and tyres to use?Any advice on how to go about fitting the wheels in with this setup?Any practical challenges you may have solved previously with something like this?Is keeping the drivetrain etc. a good idea?Would I be able to change the handlebars if I wanted to?
