What have you bought/upgraded today.

Post-script: I broke my new carbon front wheel second day out. Lost traction just before a creek gap, I cleared the gap, but my bike didn't. Broken spoke and rim sidewall damage. Happened Sunday, pics submitted Monday afternoon, new wheel shipped out Wednesday morning. They want me to send the old wheel back, but nice to get the new one on the way so fast.

Bontrager apparently is releasing an updated Line Pro 30, which they are sending me. Pretty sweet. I think the first gen (which I broke) had some durability issues. Perhaps proving the adage of light, cheap, strong...choose two...

New rubber too. Trying the dual compound DHR2 in back, standard DHF up front.

STOKED



Oh, and I've got a set of Stan's Flow MK3 with DHF/DHR2 coming to market soon :)https://uploads.tapatalk-cdn.com/202...740d083cbc.jpg

Flat pedals, concave side to side and front to back. About 18mm thick, Should be sub 400g. I’ll post some installed pictures once I get them and install the spikes and axle and put them on the bike. Fun project

Sick. Let us know when we buy some!

Yeah, designed around the fooker (race face Chester copies) pedals’ axles from amazon. Pedals are cheap, and the axles use a solid 3 bearing setup which is nice.

Picking up mine tomorrow...only decision left is traditional xt clipless pedals which I always had....or with small platform added like you have

I'm not in it for the platform. My old ass knees need the Crank Brothers float, and you can pick those guys up for about $30.

Finally...wow what a ride too. Does everything better than my previous hardtail, especially climbing. Settled on shimano saint pedals, like those so far too. Attachment 334280

First ride with that giant 52 cassette yesterday. So nice to go from 30x42 1x11 to a 32x52, I can actually ride up hills again!

the one and only ride since i got it last friday where i took some jarring hits on decents and now lower back has been shot. might need to add a fork already.....can't think of anything else i did to put the pain in my back.

Are you using the newish Shimano Deore 11-51 11-spd cassette? Like it?

I'm considering picking one up to get a wider range than the 11-42 SLX cassette on one bike.

I'm on XTR 10-51 and it's amazing. My buddy's on SLX 10-51 and he concurs.

Just cause she's not a dentist doesn't mean she can't be treated like one :cool:

Pike w/ Push ACS3
XTR drivetrain and brakes. Yes that's a 28x51.
Chris King/Santa Cruz Reserve wheelset
Chris King HS & BB
Raceface carbon cranks and bars

Thanks. I'm not likely to swap to 12-spd Shimano on this bike (not sure if it's possible to get a micro spline freehub for the Race Face Trace hub), but a wider range 11-spd for cheap sounds good.

I didn't read your post correctely. I'm not sure the new Shim 11sp option uses standard 11sp spacing. Since it's an option for the new 12sp, I think it uses the same 12 sp spacing, you just lock out the uppermost limit screw.

There's a way to look that up instead of just guessing or whatever

https://productinfo.shimano.com/#/co...432&acid=C-434

All the 11s cassettes still listed as compatible with all the 11s shifters/derailleurs including new m5100 and they still fit on a 10s freehub.

That's a good chart, thanks.

Just bought a Camelbak Chase Vest. Loving it thus far. My hip pack always drove me crazy.

All you folks with 30+ tooth chainrings wanting lower gears - why not just downsize the chainring? Anti-squat worries? Need that 30x10 top end?

First thing I did when I got a 1x bike (with 10-42 cassette) was to swap out the 32 tooth chainring for a 26. I occasionally spin out the 26x10 but mostly just on the road where I don't really care how fast I'm going.

HG has 11t as the smallest. 96bcd chainring smallest is 30t. If you don’t have XD hub or direct mount chainring, it’s a little limiting, thus the large climbing cassettes.

Speaking of which, anybody have an 11-46t 11s HG cassette laying around? Doing some 50+ mile backcountry rides with 10k climbing and want a bailout gear.

Check out the gearing on the Deore 11-51 -- it's available online for $65-70ish if you look around. I'm pretty sure I'm going to grab one. I bet it weighs a decent chunk more than, say, an XT 11-46 -- but I think the cog spacing is much better.

That's a huge difference in gearing for where you are. a 46 in the back on the 1x11 with a 30, unless you're super burley or a single speeder by nature is a must.

Yeah, I don’t want to also buy an SGS (long cage) derailleur. My SLX mid-cage won’t shift that big sucker and if I were spending that much more, I’d just go full SLX-12.

Yeah, I mistakenly thought you were referring to the Shimano option of using an 11sp cassette with the new 12sp RD+ platform.

Exactly. First ride out I was over 12,000' three different times. And finished on a slightly downhill road where I normally would have spun out. I'm a fan.

The last climb up to the top of 401 will always be a granny gear bar for me to judge my ratios and my fitness.

Interesting, how does that work?

I do notice in the chart that the m5100 and 4100 rear derailleurs are listed in both the 10s and 11s charts so that's kind of handy. Which kind of implies that maybe other shimano 10/11 mtb stuff can interchange?

I’m on a five year old 27.5 trail bike with 32t and 11sp 11-46 and climb a lot. I wouldn’t mind a touch easier granny gear but I’d far rather gain more top end at this point. I’m spinning out on flat single track and bike paths. I can’t imagine a 28t or 26t in those situations.

A 29’er with a 28 tooth front chainring and 10-42 or 10-50 has a higher top end gear than your setup ;) that’s why some people are good with a 28 tooth ring.

10 tooth vs 11 tooth is a big difference and wheel size matters. I have a 32 tooth front chainring and 10-50 on a 29’er and can easily spin into the upper 20’s. To replicate the same top end on a 27.5 bike with 11 tooth you’re likely looking at a 38 tooth chainring.

They are sweet but be careful what u put in the chest pockets. I’ve lost more than a few things on descents.

Ahh ok that makes a lot more sense. I should’ve consulted the gearing ratios chart! I’ve been wanting to switch to a 29ers so that’s good to know.

It’s both gear ratio AND inch gears to consider.
There are many factors involved but to simplify it:
A 32x10 on a 27.5 gets you 88” of forward movement for one full rotation of the cranks.
A 32x10 on a 29er gets you 92.8” of forward movement for one full rotation of the cranks.

Same gear ratio of 3.2 but different inch gears.
Pedaling at a cadence of 100 in 32x10: (simplified)
27.5 = 26.2 mph.
29er = 27.6 mph.

They offer an 11sp 10-45 cassette with the same 12sp spacing for the XC race crowd. You just use the limit screws to lock out the derailleur. Saves a few grams and gives tighter gearing if you go 2x.

If you can borrow a 28t before buying one, or find a cheap one, It would be worth it. Most FS bikes (at least the ones I've owned/looked at) are designed around a 32t chain ring, 30t at the smallest. That 28t is gonna increase the antisquat in most cases. It may or may not bother you, but the difference is noticeable.

I’d really recommend rolling out your wheel/tire combo as well when figuring out your gears. Tire size will make a huge difference.

2020 Switchblade PRO XTR.

Mostly stock at the moment but I added:
Ridewrap (poorly)
Shimano XT Crank with Wolftooth Boost spaced chainring
Swapped on a 2.5 Aggressor in the rear

i9 wheels and stem on the way. https://uploads.tapatalk-cdn.com/202...8923ac97d2.jpg

XtrPickles sighting! Glad to hear your bones haven't disintegrated and you're riding bikes.
