Hi MachineeBay. I purchased mine for about $100 under what QBP (wholesale in the US) sells them for. If you don't need them right away, just set up an alert.
Hi PeterI still don't understand why anyone would choose T47. It makes no sense.
Regardless, in the US, I just purchased a set of taps for a repair (paid for by them) and they cost about $400 wholesale. Now I have them but can't see why I'd ever use them.
I agree that it's a worse bike, weaker in certain areas and definitely a pain to change cables/hoses. But some people like the aesthetic appeal of internal cable/hose routing. For those that do, the T47 is a convenient option, but I agreed not the best technical option.Why build a worse bike around the routing? That makes even less sense.
1. It's very large and heavy when there are more compact and lighter shells freely available.* can opener and worms at the ready *
Can you explain why it makes no sense?
Hi Peter1. It's very large and heavy when there are more compact and lighter shells freely available.
2. It's threaded, which is an incorrect interface on the frame.
3. It's expensive to produce
4. It forces bad geometry in mountain bikes
5. It solves no problems.
RE:I'm really interested to understand more on 2 & 4 if possible, just for my learning in terms of the bad geography and incorrect interface?
5 I guess is whether you think it helps internal routing if that is what a customer wants and whether it helps to solve that. Not fundamentally a problem to solve as such.
Good info, thanks Peter.RE:
2 - Bearings are not located using threads. That is not how engineering works. Bearings are located with bores. Show me a bearing on a car, motorcycle, airplane, machine tool, submarine, etc that is located with threads, you can't (baring some insane special case). Definitely not for a simple spindle.
4. Most quality hardtail mountain bikes will have 400-410mm rear centers, a little longer for very tall people. There is very little room between the tire and crank shell when using 622-62 tires and a 1.75" shell. Going to a 2" shell only makes this worse. I just don't see it pulled off well.
5. Internal routing is not a solved problem. Internal routing is a problem. Internal routing is a very low performance choice. It's sick on Instagram, not so much for folks that take the bike seriously. I'm sure folks want it but then again, I'm not interested in low end bikes.
The engineers aren't debating this. There is just one answer. It's the kids in bike shops that imagine that they know anything about engineering or mechanics that seem to think that threads make any sense. Really. Show me another example anywhere where spindle bearings are threaded into place.On point 2, I'm sure there is more than plenty of anecdotal evidence for and against threaded and press-fit BBs on bikes...
I've been using the Wheels Mfg BBs. They are super solid and dead quiet.PVD where do you get you BBs from?
