    My DIY builds: GMAC, BBSHD, 9C RH212, CYC Photon, ToSeven DM01, Grin All Axle

    Well actually I have been trying it myself since I first got into mountain biking in the early 90s (before suspension forks) and having continuously upgrading frames/forks (more travel) ever since. The general rule of thumb is adding 10mm of travel slackens the headtube angle by 1/2 degree...

    Soma Juice ToSeven DM01 install I got my m5 turnbuckles (5 for $13) but they dont have the adjustable thing out lined in red in the attach pic.. See the other attached pic for the turnbuckle I have. I have been modifying/bending the mounts but they are now at an angle that I need to ovalize the...

    My DIY builds: GMAC, BBSHD, 9C RH212, CYC Photon, ToSeven DM01, Grin All Axle

    Soma Juice ToSeven DM01 install I have started the process of installing my new unused ToSeven DM01 onto the Soma Juice replacing the CYC Photon. Both the CYC Photon and BBSHD have a chainline of 52mm when installed with driveside bb spacers to clear the chainstay. The DM01 with 42t offset...

    Surly Ogre GMAC After about a year without the GMAC Ogre, I decided to get it back on the road to sell since I had all the parts and a now spare ogre frame. This was replaced by the CYC photon as from a thermal perspective they seemed to be the same on my rides and the CYC had better torque...

    Soma Juice #2 (BBSHD) I like my CYC Photon Soma Juice so much, I decided to build a second one(BBSHD) for off days where I just want to go faster or for the windy days we have out here in the plains north of denver. Scored a Fox 34 AWL shock (ebike approved..thicker wall stanchions) for $300...

    Tubeless or Mr Tuffy and sealant in tube for goatheads?

    Stans sealant in tubes has been working fine for me since I started using it in 2007 with only 2 flats since (due to dried out stans, adding stans fixed the flat) Tried tubeless many times and its just not worth the effort and mess, especially if you have a quiver of bikes. I live north of you...

    The Soma Juice 29r has a little longer top tube and slacker head tube angle (see attached pic). The Ogre is a a commuter based do-it-all bike and the Juice is a MTB based do it all bike. Took the Soma out for a ride today and LOVE it. Only issue was it was super windy which isnt the best for...

    Soma Juice 29r Update Finally got the Soma Juice 29 build built about 5 minutes ago and did a quick 5 minute ride. Many parts came off the Surly Ogre its going to replace. I did put on a RockShox Gold 35 ebike certified fork ($269, on sale from $459). It also got a new 9 speed 11-46t cassette...

DM01 Fitment on Surly Ogre and Soma Juice 29r The DM01 fits both the Surly Ogre and Soma Juice 29r using a 1mm spacer The chainline is around 57mm with a 1mm spacer to allow motor...

    Tubeless or Mr Tuffy and sealant in tube for goatheads?

    Yes, I have had that happen with tubeless setups as well (weeping thru the sidewalls) on several tires (some tubeless ready, some not). Not too cool if you store the bikes inside during the winter. Best tubeless setup I ever had was on a 2019 santa cruz tallboy which came with sealant...

    Bought another photon and this one failed also.

    Sorry to hear yours stopped working so soon. My Photon has 2k miles and is used every other day without any issues. I dont use a throttle on this setup (not required and just causes motor to overheat). I also always monitor the temps while riding I also have run two BBSHD with a combined 10k...

    Tubeless or Mr Tuffy and sealant in tube for goatheads?

    So many opinions and experiences here so I will add mine. 99% of the reasons I get flats is because of goatheads. I started using stans in tubes around 2007 and have only had two flats since (stans had dried just added more stans). Im guessing I have 10+ goatheads on each of my bikes at the...

    Soma Juice 29r Initial Frame Impression Just received the Soma Juice 29 frame and must say Im am totally impressed. The Desert Metallic paint matches the Surly Ogre Champagne Supernova which I totally love. As can be seen from the pics, it has tons of mounts just like the Surly bikes I have...

    My DIY builds: GMAC, BBSHD, 9C RH212, CYC Photon, ToSeven DM01, Grin All Axle

    New MTB/Bikepacking/Touring frameset I originally picked the Surly Ogre (and Troll and Bridgeclub..sold awhile ago because I prefer 2.35+ 29 wheels) because I needed a 42t chainring to be able to pedal at 90rpm cadence at 28mph. While the two Ogres are excellent bikes and have served me well...

    California ebike states somewhere that the 42t chainring can only be mounted on the outside of the spider. Nothing said about the 46t so might be able to get a better chainline with the 46t mounted on the inside of the spider. I emailed california ebike on getting a 46t offset chainring and...

    Torque or Cadence -- which do I have?

    You would need the torque sensor (obviously) and a controller and display to go along. Might Even need a different motor (that would be compatible with motor controller) Best bet is to contact Grin at ebikes.ca, they have a video on converting a Rad to torque sensor

    ToSeven DM Series Mid Motors

    I was aware of such issues being an early adopter of the DM01 and was willing to take the risk, whats the fun of blindly following someone else, that would make you a lemming 😀 . I really didnt see the bad chainline thing coming though, totally caught me offguard. I was in the final stages of...

    ToSeven DM Series Mid Motors

    As always thanks for all the info: The Linkglide 9 speed is actually pretty reasonable My two high power high mileage bikes (Surly Ogres with CYC photon and BBSHD) previously had KMC e9 chain($40), SRAM X5 9 speed shifter($32) and derailler($50) and HG400 11-36 cassette ($30) for a total of...

    ToSeven DM Series Mid Motors

    I have used KMC e specific chains in 9/10/11s exclusively and have never had an issue for likely 20k miles. But yes, they are $$$ I am now transitioning to the Linkglide system on all my bikes. All 9/10/11s are compatible in that cog spacing is basically 11s. In addition the cassettes have a...
