hrmf. i may be the exception, but i just got a 2018 frame and the only thing i needed was a new rear hub and a wheel rebuild. if staying 26 is too low, i’ll get new rims and tires and be done with it.
what bike did you get? I sort of missed my opportunity to do this with my new-to-me transition patrol last summer. I would have tried my existing 26" wheels in it, but the new bike was 11-sp with an XD driver, and the old bike was 10-sp with a "shimano" freehub. So I couldn't just swap wheels over despite some hub dimensions (142x12).

New fork as well maybe? ...or do you already have a 27.5 fork with 26 wheels?

I'll be interested in hearing about how you like your 27.5 bike with 26" wheels. My current bike is built with super high-end parts and it's unlikely I'll have the funds to buy a similarly spec'ed bike when I'll need to replace it. Buying frame only and transferring most of the parts seems like an interesting option. Let us know how it goes.
I'm 2 for 2 on doing that happily. It's still a bike.

Same here. Two 27.5 frame/fork combos running 26" wheels. No issues. Granted, am running both forks 10mm taller than "stock geo" numbers, and relatively largish tires which helps with the patented YurgonnadieBBH.

Plan is to keep doing the same until my stock of 26" tires is used up.

I'd expect sram to change the clamp on their shifters next so it only fits on some new Truvativ bars that are .5mm bigger in diameter.

and said shifter will also include the lock on clamp to the SRAM grip with biometric reader, needed to unlock your SRAM system to actually work.
it's the N.O.E.M - no other equipment, man.

So it all boils down to Trek and their stupid PF92 BBs, and SRAM not being able to sell them cranks because the BB30 spindle is too short. That's why YT kicked them out and went straight to a Shimano/E13 combo.
SRAM GXP cranks fit PF92 just fine. It's a 24/22 mm axle.

Sram could have just kept on making BB30 specific cranks (narrower spindle thank their GXP and WON'T fit in a PF92 shell width) and their GXP cranks.

Instead they looked for a way to make one cankset but keep the bearing / seal quality of their GXP cranks.

RaceFace, E13, FSA, and others are the ones that have been making a 30mm spindle wide enough to fit with the width of PF92 bb shells and have been running bearings with almost no sealing. These is a shitty solution.

To eliminate chain slap. That's not a trade-off I'd take for the extra friction but to each his own. The pictured bike design does have an annoying amount of chain slap when paired with a Sram derailleur. The simpler solution is switching to Shimano and cranking up the clutch.

Edit: On second thought, it might eliminate the need for a guide at the top of the chainring so, while inellegant, it wouldn't add weight and is maybe a better solution than what I'm running now. How much friction it contributes (and aethetics if that matters) would be the deciding factors but I'd love for my fleet of Santa Cruzs to be quieter on rough downhills.

Last year, while building my Spartan, I drank the lizard piss and bought an oval ring. After hours of reading what I'm certain are paid-for reviews by the lizards, I bought an Absolute Black ring. "The machining is gorgeous!" and "works flawlessly", turned me to spend $70 for a piece of 90% missing aluminum. When I opened it up and took a look at it, I just saw a N/W, offset ring. So what's the big deal? Does it work? Yep. That about sums up my review.

For my Big Pig I'm building up, I wanted to go back to my bright, mismatched, yet clean looking builds to avoid the "boring black" build I did on my Spartan. I looked at Raceface, but they're all black anymore. I found out that Hope is now offering cranks and rings.

To get to the point- Wow! I'll take pics later, but there's "divots" in the valleys of the teeth that was made with a ball mill allows the aluminum to be thicker/stronger without interfering with the chain. It -might- be a little bit heavier than a One-up or AB, but we'll wait and see how it works. If I get a chance I'll weigh them later.

Or was it Charge and their 3d printed Ti dropouts? How the hell was that nearly 5 years ago?
https://www.bikerumor.com/2013/05/20/charge-bikes-3d-printed-titanium-bike-parts-production-begins/

Doesn't look like they're using them on their current Ti bikes.

IIRC Fabric was originally spun off as Charge's saddle brand - apparently bike manufacturers didn't want to spec a competitor's saddle. But call it the Fabric Scoop instead and they were perfectly happy to do it... o_O

I think you'll find it actually stands for, No Other Equipment, Moron.

Tool path. Prob done via kellering (2d steps to make 3d profile).

This?



Probably just shaving a few grams of unstressed material off.

I see this device, and I hear your thoughts.....I just use 3M rubber mastic tape on my stays to quite things up and a small upper only guide (full guide on v10) and all is good, this thing looks too fragile or tangly or potentially frictiony

Yep, them's the ones.

I thought it was because the material was thicker than most rings to add strength and milled there to allow the chain to clear the eccess material.

I had one of these rings. Didn't work without a chain device. Curious about your experience will be.
