No, the Freestate is famous for its hills... When I first moved to Bloem I was told the joke that the Freestate is so flat...; you and your wife would have and argument and she leaves. 2 Days later you can still see her on the horizon

But... The SS is not out of my mind yet........

A lot of great info thx guys. The euphoria has worn of a bit I am afraid (wife's). But you did give me a good idea. I might change the front x3 with the oval Rapide cog and make it a 1x9 system. Too many gears confuses her and she almost always goea to the front to change when things goes south. This would make it less complicated.

Gotcha

Ok cool. Just had a look on Rapide and I see what you mean with the distance. Thanks for that. You mention the chain will keep falling off. Is that because the derailer is not present anymore? So I will have to buy a new chainring that can work without a derailer

So far the discussion is about the front chainring. you guys are suggesting 32t or 30t. Looking at the Rook Cycles site they are selling 44t and 48t chainrings. Why would they only focus on these big sizes?

Will do so over the weekend

Thanks RW Look the riding she will be doing is mostly urban with the kids either following her or with a kid on a bike seat (current setup). Nine out of ten times the bike will not see a 'trail'. But I will keep the oval chainring in mind when the time comes and she wants to do a bit more adventurous stuff. you mentioned: "Now that you know which it is you can then measure the BCD of the chain ring (This basically only applies to 4 bolt chain rings) - the way you do this is by measuring the distance between two diagonal bolts. Now I can guess with probably a 99% certainty that the 3x has a 104 BCD" Educate me why is this needed? The bike is a 650b.

Thank you very much for the info. Maybe a mod can move the thread to the Single Speed section. Thx

Hi While keeping busy during the lockdown I am browsing bike sites. Found Rook Cycles https://rookcycles.com/ My wife fell in love with the colors and what not. So...I am planning on converting her bike to a single speed. Now, I have ZERO experience in building and speccing bikes. Thus assistance will go a looong way in assisting me with the project. Info on her current bike. She has an Avalanche Prima Donna (year unknown). As I was upgrading my bike she got my old parts to upgrade her bike also.(the Prima Dona is a VERY basic bike!!) So far I have upgraded her gearset (my old 3x9 from my big nine 500) and she has a upgraded fork and hydraulic disk brakes. With the gearset change I also had to replace her rear hub as her old hub was not compatible. It's a Shimano 36 spoke hub. Ok so the idea is simple. I want to put a freewheel cog on the rear. and the front setup needs to change to a single chainring. 1st question. Can The cassette just be taken off and the freewheel be added? Or will I need to replace the rear hub also? 2nd question. The front (3 chainrings); I see people are mentioning that mtb cogs have 4 bolts and standard cogs have 5 bolts. Does that mean that I will have to replace the entire crank system for the conversion? OR, can 2 of the chainrings be removed to only leave the big one? (this might be a dumb question shedding further light on my ignorance on bike upgrading) **Note to self, I am too reliant on bike shops** 3rd. question (if I need to replace the crank). Will I need to replace the bottom bracket as well or will the new cogs work on the current one (assuming its a square bb)? https://rookcycles.com/collections/parts-and-components/products/crank-set-chain-ring I can't find decent specc info on the Prima Donna to know the ins and outs. What I can tell you is that the complete groupset came off my Merida big nine 500 (2014) if that helps. I think that's about it. Fire away!

People in Stellenbosch are chops thats why ???? Hard tail kicks ass
