I'm still written off by this chest thing. Feel about 75% but any kind of exercise triggers a coughing fit with a load of junk sitting in/on my lungs. Have actually thrown up a couple of times from coughing so much, once this morning when I got to work. Have given up, I'm reaching the 3rd week of it and have booked myself into the docs... In 3 weeks time (earliest appointment ffs!).
Skipped the turbo this weekend as low on sleep but really need to do something. My fitness has taken quite a hit, I was making nice progress after my holiday but now that's all been thrown out the window. The last 8 months have been a constant peak->trough with illnesses, holidays and crappy weather. Maybe I'm asking too much with having a youngster, but without setting some ride aims I hadn't got any challenges to look forward to. The two imperials I had lined up this year, one has been cancelled anyway. T
he other is next weekend and I really don't think I'm going to be healthy enough to even attempt it.
Or the 70 mile version I did last year.
Weather is just so odd and localised currently down this way which is probably the most frustrating thing. Could head out in bright sunshine and by the time I'm over the hill (no jokes please) it's damp or raining, then 20 minutes later nothing. Luckily it's quite warm so if it is only light then don't need to wrap up as drying off relatively quickly!
Very similar to here, with Hereford in a bit of a 'bowl' the winds tend to swirl around bringing differing weather with them from the various surrounding hills. We've got Wales to the west, the Shropshire hills to the north (Clee), Malverns to the east and the Black Mountains/Brecon Beacons to the south. Makes for some fantastic riding but you can get all seasons in some of the longer circular rides...
I think your kinda stuck if that is your BB Roady as the cranks are fairly bespoke to Praxis.
Different size crank axle one side to the other hence the 28 and 30mm ID bearings.
The width of the BB doesn’t really change much now as most are press fit 30 or some variation on that. And the sleeve if it isn’t part of the construction of the BB (like BB manufacturing/infinite etc which thread together and expand) doesn’t really add anything anyway.
If the cranks were BB30 you could just throw away and fit just about any PF30. You’ll have to get Google as to who makes M30 Praxis compatible ones!
Yeah I know I'm stuck with this BB:crank combo so that's kinda why I was asking about frame compatibility when it comes to switching BB's. I think this Praxis is just a 'normal' BB just the NDS bearing has the shim/spacer to make it 28mm ID. The cranks with the NDS step down to 28mm are where the 'problem' is with compatibility. The bearings are the same both sides. So I could replace the BB with a 'normal' BB (the
Wheelsmfg PF30 is looking the likely one, it's very well regarded and they even do spacers for it to be used on Specialized OSBB carbon frames like mine). So that would open up the cranks I can use to anything with a 30mm spindle - I just need to decide which. To be honest I could do that with this Praxis BB - just change the NDS bearing for a normal one without a shim in it, presto 30mm ID.
To be honest part of me thinks I could long term use Shimano adaptors on the wheelsmfg to make it a 24mm spindle as I have Ultegra cranks on the turbo bike I could then use. I could then fit a Stages/4iiii crank arm PWM to it with the bike becoming my commuter/winter bike. BB on Turbo bike being 24mm ID I could refit the original FSA Gossamer as it's 110BCD 5 arm so would be compatible with my Powertap C1. I could get new 30mm cranks (Quarq Dzero/SRAM Red) to use in the medium term on the Diverge (before the Ultegra swap) with the intentions for them to move to a new bike...
With the BB being the focal point, but having lots of options, the cranks I use will really have to decide it. For now it looks like 30mm cranks are the way forwards rather than stepping down to 24mm Shimano. There's just more options! I may even have found some Specialized carbon cranks for a reasonable price, but the guy is over in the states and I've no idea how much shipping/import will cost!
Still a bit of a lurker / reader / non poster in this sub forum, but here goes
Me and two mates have a bit of a (relatively) regular Sunday morning casual / social ride which usually involves a coffee / breakfast stop and plenty of banter we average 40-50 miles but got up to 70 odd in the summer months of last year
Anyway way out last weekend and about 25 miles in, just going through Macclesfield and intending to go up to the cat and fiddle when a nasty grinding sound and skidded to a halt to find my mech hanger snapped catapulting my rear derailleur into my back wheel ....<snip>
Ouch! Glad it happened on the flat/easy riding along and not a descent. Hanger looks quite a weak design, as it's really thin where it snapped?!
Great pics btw, greyscale really works well with filthy components, although that RD does look really really clean...!
the bike had recently had a good clean including the cassette, chain and jockey wheels so was a blessing when working on the Fixie conversion
