I have not tried but would a older 26" specific frame be big enough to accept 29er wheels? I tried a 650b front wheel on a 26" fork and it didn't fit. It had knobblies on and I know you mentioned tiny slicks but would it make much difference?Not being difficult, just interested to know. Some 26ers could fit 700x23c wheels and tyres. My CAAD4 F3000sL did
dirtypot Posted October 17, 2019 Posted October 17, 2019 I'd go with the 29er. Bigger wheels will roll better.I did a roadie ride on my 29er full sus a couple of weeks ago - 100km with knobbly tyres and only a 34T up front and I still managed over 25km/h average. 29er wheel also gives you the option to run a 700c road tyre if you really want the maximum advantage. It looks weird, but it works.

The right answer if you want maximum speed advantage. On 10/17/2019 at 7:16 AM, Long Wheel Base said: That would depend on the frame?

See if your 29" wheels with any road 700c tyre will fit in the frame, it may well do. See above. BUT: Remember the maximum pressure on a 29" MTB rim. It may not like the 10Bar you like to run your 23c road tyres at if that is the biggest that will fit.
matthieup Posted October 17, 2019 Posted October 17, 2019 I did my first CTCT last year on my trail dual sus 29er (Trek Fuel EX8). I did put slicks on and put back to original 2x11 for better gearing. For this year I'm considering getting a light hardtail 29er that I might use afterwards or get a road bike (not sure about the V brakes), all of it on a budget. The main reason is that I'd like to do the MTB argus and don't feel like making to many changes to the bike too often for the various training.

The wider hubs do fit the cannondale but you need to stretch that frame and it really isn't ideal. The narrow hubs don't fit the burley at all, you need to squash the rear triangle and then the skewer takes a lot of outward pressure.

The frame was disc specific. You need a disc brake frame and fork for this to work. V brake bosses are not positioned to accommodate 700c rims brake track
Super Sywurm Posted October 17, 2019 Posted October 17, 2019 In this case, I would use the 26" bike. I have one 29" dual susp bike I use for road and off road riding. I have two wheel sets, one with slicks and one with nobblies. Works for me. This is what my bike did the past weekend (29" dual susp, with slicks, +- 15kg bike) New Bitmap Image.bmpFetching info...

I did the CTCT twice on 29" hardtails with nobblies. My time was around 4h20 for both races.
Schmorglebot Posted October 17, 2019 Posted October 17, 2019 My 2c: It's unlikely that you're going to need your easiest gears for any of CTCT's climbs, but you will need top end along the M5 and on the descents. If you don't have top end you are going to lose any ground that you made on the climbs as soon as the road flattens out and you'll spin out on the descents. Definitely get slicks, and consider a smaller range cassette, you wont need all those easy ratios. With a 26t upfront you can get away with an 11-25 The 26" will certainly be comfortable enough, certainly more comfortable than any road bike.
ridr Posted October 17, 2019 Posted October 17, 2019 Personally, I prefer the feel of the bigger wheels of my 29er full-sus compared to the 26er hardtails I have (no science involved in my opinion).
JohanDiv Posted October 17, 2019 Posted October 17, 2019 Enter the CTCT MTB Challenge, do it with the 29er..then the following weekend do the CTCT on the 26er. That way you get to enjoy both your bikes
