erm, are you 1st? no, keep pushing
Haha ffs. Guy from my club just took the long standing KOM. 13:57. Outrageous.

David Millar did 13:35 a few years ago
There is no benefit to ceramic as a material over a steel bearing.
The benefit of ceramic is that it can be machined to a smoother surface than steel to create a smoother rolling bearing. It still needs all the precision machining work put in to make it a better bearing though so a cheaply made ceramic bearing will likely be worse than a properly machined steel bearing.
(ok, maybe ceramic doesnt rust so that would be a benefit over steel but if your steel bearings are dry enough to start rusting then you're probably not all that bothered about rolling resistance anyway)
Giant website says it takes a standard shimano external threaded bottom bracket, so that's hollowtech ii to you and me.
my shoes are finally going kaboom after around 8k miles in all weather got a hole near my thumb, peek-a-boooooo

Somewhat baffled how we're concluding a 2015 defy 3 takes a press fit bb when the giant webpage for the 2015 defy 3 says it takes a htii bb
Bottom bracket posted won't fit no. If you want to renew the actual BB you need new pressfit bearings.
They look like this: http://www.chainreactioncycles.com/...mHwjLpPZdUaW7eKMsSwf0aAu-v8P8HAQ&gclsrc=aw.ds
The crankset will fit though.
15:35 Lap of RP tonight, perfect conditions.
Ceramic ball bearings might potentially be better but the cage will still be metal and could rust or tarnish.

a 2015 Defy 3 100% takes a HT2 bb, its only 201 Defy 2/1/0s that use the AluxxSL frame with pressfit bb shell.
So, my legs are still pretty knackered from the weekend. Damn recovery :/ Also, without being as detailed as Roady might be in this situation, saddle-soreness is pretty bad. Possibly having to ride the last 150 miles on a broken saddle didn't help...
Really? I bet it's all downhill amirite?
I've done less than 2k and my shoes are starting to burst at the seams
edit: Dodgy Tioga Spyder saddle is great but yeah, it broke... Still, I got two replacements for $12 so it's not too big a deal.
how did it break? mine's still going strong! plastic is a little shinny but it's geeewwd otherwise!
The original saddle I bought was the more expensive Chinese knock-off and the plastic on that version is thinner/softer. Not more comfortable though. It started to break a little bit about a week back and then on the ride it just got destroyed. Probably didn't help that I was carrying a backpack filled with food and spare bits.
If you look on the map then Manc > London is all down but London > Manc is all up - way harder
Lol, that bit exactly...maybe...who knows
OneMoreSolo rode London to Manchester a year or so ago. Looks pretty gruelling
