Originally purchased 3/2014 some upgrades were done in the following months. Currently undergoing additional upgrades & retrofit. Replace the brake levers, bar, seat, front & rear calipers (red anodized bearing covers - ceramic/metallic pads) & rotors, chain & dérailleur. Also installed Acera 7 speed trigger shifter. More about the Tourney TX75 dérailleur later but note in the pics there is no cable hoop at the back of the bike. This Tourney is straight pull and redesigned articulation. Mounted the Devistator tire up front & Vee Mission on the rear. Regreased & adjusted the BB & front wheel bearing. More on the brake kit later too. Very pleased with the bike & still have less invested than the revised sell price at Walmart :mrgreen: Currently undergoing additional upgrades & retrofit.

3 years later in it's current form & pending retrofit. First batch of part for the Dolo. That's the latest straight pull Tourney that replaces the TX series. Note the cable receiver is turned up toward the seatstay to eliminate the debris catching cable loop. Yeah I paid 6 bucks a piece for the Surly rim strips. Wanna see if they resist fade or cracking any better than DIY jobs. And that's the SunRace version of the 7 speed 34T Mega freewheel. The other is a Sun Race 8 speed 32T freewheel that I previously tried with the original crank, but the chain rubbed the back tire. Might try to fit it again since the chain line changed with the 22/32T FSA crank it's got now. With the "4.8" Surly Knard back there I won't hold my breath. Do they make freewheel spacers I wonder? Anyway, I'm happy with a 2x7 anyway so no big deal. Oh yeah - yes, that's the new optional shotgun flashlight derailleur attachment Shimano is offering...

I've discovered you're not an initiated fat bike owner until you've installed a set of rim strips. I've read on other forums that people have cut them to get 'em on the rim. Don't. The Surly 50mm strips are nylon, not rubberized material, so they don't stretch much. It's one of those things that if you did it more frequently it wouldn't be an issue. HOWEVER, the first time is rough. It's tighter than Melissa Gilbert on the Little House back lot. I used tire levers - only after realizing that bare hands & a crossbow-cocking stance weren't gonna do it. Make sure to line up the valve stem holes before you start...(Yeah I know - "that's what she said!")

Headset retrofit - For folks that may not have done this before, here's few shots of the easy way to do it. After you have the fork off, you'll want to remove the bearings from the housing. The Dolomite comes with captive bearings so the balls won't fall around the work area.
You can use a screwdriver or pipe & whack around the edge of the bearing cup but some are really tight & might bugger it up. May not be an issue if you don't plan on saving it.
I opted for a removal tool from Bike Hand. Think it was $8.00. Makes life easier even if you don't use it often.
I tried a dry lube last summer. Any grease just acts as a carrier for grinding media - that would be the sand out here that just wont stay out of any unsealed bike bearing. These will be saved in case the stock fork goes back on or is used on another project.
This is the new headset with "sealed" bearings. $10 on egay so we'll see how it does. Want to keep the low budget theme for this rebuild. Will install it tomorrow & post photos.

a good tool is always a worthwhile investment. i have gear pullers i've used once and will likely never use again, but i don't regret getting them.

Finally getting back to the Dolomite this weekend. A personal record for taking the most time to rebuild a bike Having a second fat bike seems to have lowered the priority meter a bit. Running the new cables, installing 180mm rotors & new pads, axle bearings, chain & rear derailleur. OK, at least 4 out of 6 of those tasks...

this could be interesting. Afraid not. Just a dead refrigerator & scrambling to save food, decide if it could be fixed or buy a new one, etc. AND placating the dear wife so she doesn't pull her hair out fretting about it. As any married guy knows, that last part is really the first priority.

the big holes in the rims are to save weight? Yes. Negligible on a 45-50lb bike. But it looks cool too with a color contrast rim strip showing. That's the way these rims came but take a look at what blown did with his rims in his Beast thread. Great rim work but I'm 225 -230 lbs so I'm not sure how comfortable I'd be giving them a workout on rocks & XC. I guess lots of guys have drilled out the rims on Walmart fat bike with no issues. Or those that did have problems didn't fess up.

Repacked front bearings on the Dolomite wheel, which is actually on the Hitch. Bearings & outer cone looked OK. Some minor wear on inner cone in hub. As a note, my Dolo was made in 2013 & has 8ea 1/4" (aprox) balls per side. Another forum reported 9 balls but I question if he added one when replacing his axle. Curious if any other Dolomite owners have looked at the front bearings.
