    Hmmm...something seems strange here...

    Something's not quite right with my Sweetspot...

    No brakes and 650b wheels ... look how high the BB is on that thing
    I used to ride to Win ... Now I ride to Grin

    While my guitar gently weeps, my bike sits there mocking me

    It has brakes now, but still no real test ride yet. The SID definitely does not accommodate this size of tire. BB raised 0.375." I'm curious to see how it all works together. Eventually...

    So I finally got a ride on the new wheels. I had to swap out the front fork, so the ride was done with a 2008 Fox F100R on the front. Bike gained about 2 lb with this conversion, but at least one pound of that is in the tires. The Cobras are heavy compared to what I had on the bike in 26er. Short review is: This was a success! I rode on a trail where I have never used this bike, so I can't really give a great back to back, but the bike rolled well (perhaps one sees what one wants to see?), and the geometry changes (higher BB, more trail) took away that bit of twitchiness that HG's have in stock form. Bike was still very nimble (trail was very tight) and very stable. If you're a hardcore fan of the very quick steering of the Sweetspot, you might not like this. I prefer the linearity of this setup so far - looking forward to a ride on my official test trail to learn more, but so far, so good. I like the changes and probably will keep the tires even though they are heavy. We'll see.

    Interesting CTB! I've been considering running 27.5 on my 4Banger too as there's a fair bit of clearance on it.

    I still need to write an update on this (much to say), but I would say no way, no how on a 4-Banger. The 26" rear tire on mine already contacts the carbon arm at full compression.

    4banger would be a tight fit.. even for the rocket 88 would be stretching it i think

    I'll do a test fit at some point and show some pictures, but the problem is that you'd have to crank the BB up so high for the tire to not hit the carbon arm that you'd end up with a bike that probably doesn't work at all. Of course, I've wondered the same about the folks that have Straight 6's - I'm running 4.7" of rear travel on mine, and to run any more, I'd have to make the head angle very steep (it's about 69.5 now) and raise the BB a ton. The wheel path on a Lawwill suspension moves it closer to the seatstay yoke as it moves through the travel, so bigger wheels don't package well at all.

    I've learned in my Sweetspot experiment just how much slapping on 650B's with no other changes slows down a bike's handling. Great if you felt the bike was hyperactive initially, but not so great if you are looking to maintain race speed. Again, I do need to post an update on this. I've done a bunch of test runs and changes. Stay tuned.

    Looks great. I have similar plans for my sweetspot.

    Thanks. I'm horribly delinquent with posting a ride review of the change, which I'll probably change back.

    Ok, so I’m about a year overdue on this…yikes.
    Last year I decided to get a 275 wheelset to play with, just to see what bikes it would fit on, how it changed them, etc. Since the Sweetspot frames are fairly low-travel, I thought they might benefit from the 275 wheels more than some others. Thus I picked my HG Sweetspot Monogear as the guinea pig for this.

    First iteration took some time. The 275 wheel with 2.25 Hutchinson Cobra tires fit fine on the back, but the old 2000-ish SID100 fork I had up front would not fit this combo at all. It didn’t clear either the arch or the crown at full compression, so it had to come off. I installed my 2008 Fox F100R fork onto the bike.

    First impressions were that the bike rolled well and was maybe a little bit smoother-riding overall, but the higher BB and increased trail actually stabilized the bike a little too much. I don’t like quick-steering bikes, but in this configuration, the bike lost a little bit too much of the nimble, agile feel that is a big part of the Sweetspots. This configuration also added about 2 lb to the bike – wheels and tires are heavier than what I had on there in 26, and the Fox fork was heaiver than the old SID.

    I then installed a 10mm travel restrictor into the Fox F100R, reducing travel to 90mm and thus steepening the head angle somewhat. A side benefit is a slight lowering of the BB, but not much. This brought back some of the old feel, and the Fox fork felt pretty good on this bike as well. Of course, it didn’t do anything about the extra 2 lb.
    In the end, I put the bike back to 26er with the SID100 back on there. I prefer more travel over less, so I liked having the 100mm back up front and the light weight. I think the nimbleness of the Sweetspot suits the idea of a monogear setup on this bike very well.

    It was a fun experiment, but to me, the gains in rolling weren’t enough to offset the change in handling and weight for this bike. Might be a different story on a bike with a different mission – I’m currently using that same 275 wheel on another 26” bike of mine to slow it down for handling. It was WAY too quick for its mission (5” trail bike), so it is working well in that application.

    Bottom line, 275 isn’t necessarily “better” as all the hype would have you believe. It is “different.” “Better” depends on what you want from the bike. I’m thinking my 4-Banger with a 275 up front would be pretty nice, given that I don’t want that bike to be overly quick. I actually did ride that combo, but I hadn't yet taken the 10mm spacer back out of the Fox fork on it, so the bike ended up pretty much at the same geo as 26", but with a bigger front wheel.

    Great review, thank you.

    How did the 650b compare to a 26 with a 2.2 Race King on there, since the Race Kings are such tall tires?

    I've never had the big Race Kings on the front of the Mono. I rode RK's on the front of a bike (HG4B) once and decided that was enough of that. Normally I run a 2.0 Race King on the rear and a 2.2 X-King on the front on this bike. The Hutch 275's are still taller than the 2.2 Race Kings, though.

    I'm COMPLETELY full of crap. The rear tire on my Monogear is and has always been the 2.2 Race King Supersonic, other than when I tried the 275's. The front, though, is indeed the X-King Racesport 2.2 that I mentioned, which is more like a 2.0 in size. Not sure why I thought I had bought a different Race King.

    What I found most different was the feel of the Cobra vs the Race King since the Cobra has square corners and the RK is very round. I generally prefer round profiles on the rear, and this was no exception. The Cobra isn't a bad tire, though.
